It is well recognized that lithium dendrite formation within polymer-based separators severely compromises both the safety and electrochemical performance of lithium metal batteries (LMBs). To mitigate this issue, the development of separator materials that exhibit superior electrolyte wettability and high ionic conductivity is essential. In this work, a novel nanofibrous separator composed of a phthalocyanine-based covalent organic framework (Pc-COF) and polyacrylonitrile (PAN) is fabricated via electrospinning and is denoted as PAN@COF. The resulting PAN@COF separator possesses a nanochannel array architecture enriched with lithophilic C=N groups originating from the phthalocyanine-based COF, thereby promoting homogeneous Li⁺ flux distribution. Density functional theory (DFT) simulations indicate that the COF can interact with electrolyte solvent molecules to form a desolvated Li⁺ structure, thereby enabling rapid Li⁺ transport. In situ optical microscopy visually monitored the lithium dendrite deposition during cycling, underpinning the theoretical simulations and kinetic analyses. The separator exhibits exceptional ionic conductivity (1.72 mS cm-1) and a high Li+ transference number (0.78). When applied in a Li||Li symmetric cell, the separator enables uninterrupted cycling stability exceeding 3200 hours at 0.2 mA cm-2. Furthermore, the corresponding pouch cells maintain stability under extreme shear, highlighting their practical reliability. This study presents a novel strategy for developing dendrite-free lithium metal batteries, offering both significant scientific implications and promising application potential.

Expanding the charge/discharge voltage range of the high-nickel cathode material NCM811 is one of the most cost-effective ways to increase the specific energy density of lithium-ion batteries (LIBs). However, carbonate-based electrolytes fail to adapted to the high-voltage environment is susceptible to objectionable oxidative decomposition. Therefore, two widely used electrolyte additives, lithium difluorophosphate (LiDFP) and adiponitrile (ADN), were combined to enhance the performance of LIBs at 4.5 V through their synergistic effect. The results show that the specific discharge capacity and capacity retention rate (CRR) of the Li||NCM811 half-cell with 5ADN electrolyte at 150 cycles under 4.5 V are 161.9 mAh/g and 76.5 %, significantly higher than the 118 mAh/g and 60.1 % of the standard electrolyte cell (STD). Similarly, graphite||NCM811 full-cell also has high specific discharge capacity and excellent CRR compared with STD cell. Further confirmed by physical analysis methods, the LiF-rich interfacial film between the cathode and the electrolyte called cathode electrolyte inter-phase (CEI) film, is more robust and denser. Thereby, the integrity of the cathode material is well protected, effectively inhibiting the dissolution of transition metal (TM) from the cathode material, and, ultimately, resulting in excellent high-voltage electrochemical performance of the battery. In addition, theoretical calculations show that LiDFP and ADN have larger adsorption energies for Li+ and Co4+, which can effectively reduce the deposition of Co4+ to the anode and increase the dissociation of lithium salts. This work provides a novel insight into the effective application of high-voltage electrolytes.

Pre-curing time is a critical factor influencing the properties of concrete; however, investigations into its effect on recycled concrete incorporating binary and ternary cementitious systems remain limited. This study investigates the effect of pre-curing time-varied from 1 to 6 days-on the carbon sequestration capacity of recycled concrete incorporating cement-fly ash-slag blended systems. The results indicate that the optimal carbon sequestration performance for different cementitious systems in recycled concrete is achieved with varying pre-curing time. Specifically, controlling the pre-curing time accelerates the formation of CaCO3, which constructs a dense microstructure and consequently enhances the mechanical properties. At an equivalent replacement ratio, slag-based recycled concrete achieved optimal performance after a 4-day pre-curing times, attaining a unit carbon sequestration amount of 19.41 g/kg and a 33.19% increase in compressive strength. A correlation between the unit carbon sequestration amount and compressive strength was established, defined by the equation y = 11.50x0.38 (R2=0.86). Notably, ternary cementitious systems were observed to reach carbon sequestration saturation more readily. This study aims to provide novel approaches for enhancing the carbon sequestration performance of recycled concrete in binary and multi-component cementitious systems, thereby supporting the development of sustainable, low-carbon construction materials.

Covalent organic framework (COF) membranes have garnered significant attention as a promising separation technology for dye wastewater treatment, owing to their meticulously ordered pore structure and exceptional chemical stability. The Polyamide COF (Amd-COF) membrane, characterized by amide-linkages, exhibits excellent hydrophilicity and chemical stability, whereas the polyamine COF (Amn-COF) membrane, featuring amine-linkages, demonstrates remarkable flexibility and resistance to chlorine. In this study, we present the synthesis of defect-free Amd/TA-PVA/Amn COF composite membranes with large area and continuous structure through multi-interfacial polymerization. The incorporation of an intermediate layer (TA-PVA) enables stable formation of strong hydrogen bonds between Amd-COF and Amn-COF, thereby enhancing the durability of the composite membranes. Due to the unique structural features and functional groups of the Amd/TA-PVA/Amn COF composite membranes, they exhibit not only high water permeability (119.24 L center dot m- 2h- 1 bar- 1) but also exceptional rejection efficiency towards Rhodamine B, achieving up to 96.55 % removal. Specifically, the membranes treated with a chlorination intensity of 2000 ppm exhibit stable permeance and dye rejection performance. Moreover, these membranes exhibit exceptional stability in both structure and performance over multiple cycles. This can primarily be attributed to the highest density of amino moieties and phenolic hydroxyl groups on their surface. This work underscores the significant potential of COF membrane incorporating amide and amine functionalities for high-performance separation and anti-chlorine applications.

Noted that electrolyte additives containing either B-O groups or nitrile groups are being capable of lifting battery capacity, but there is little literature on the ability to combine the advantages of both B-O groups and nitrile groups to jointly contribute to the capacity enhancement for NCM811-based lithium-ion batteries. Therefore, in the current work, a novel Lithium salt 4-benzonitrile-1,3-double (trimethylboric acid) lithium (LBTA) additive including two types groups (B-O and nitrile groups) is designed as a interface film promoter existed between the electrolyte and electrodes mainly to boost electrochemical performance in lithium-ion batteries under the highvoltage conditions. The results show that the capacity of the battery improve from 94.4 mAh g(-1) to 162.2 mAh g(-1) after 200 cycles at 4.5 V by adding 0.03 LBTA to the conference (1 mol/L LiPF6 with the solvent: DMC: EMC: EC = 1:1:1, vot. %). Further investigation of the mechanism for the capacity enhancement of the battery evidenced via characterization and computational methods showed that LBTA can preferentially sacrifice on the the electrodes' surface over other carbonate solvents to form a more stable and dense passivation layer, which derived from decomposition of LBTA can better stable electrodes' microstructure and alleviate the decomposition of state-of-the-art batteries electrolytes, subsequently enhancing the stability of the rechargeable battery in the high-voltage conditions.

Increasing the cutoff voltage for charging lithium batteries can increase the capacity density of lithium-ion batteries. Still, it is also accompanied by some adverse effects, including electrode material corrosion and electrolyte loss. To mitigate these adverse effects, this article reports on a high-voltage catholyte additive, 2,4,6-tris(4-fluorophenyl)cyclo-boroxine (PFTB). Calculation demonstrates that the HOMO energy level of PFTB is lower than that of typical solvents. Consequently, PFTB can decompose selectively to generate a robust and conductive protective CEI membrane. This reduces the occurrence of interfacial side reactions and thus protects the electrode material's structural integrity. The outcomes of extended cyclical assessments demonstrate that the capacity retention rates are 83.7% (4.2 V), 89.0% (4.3 V), 80.4% (4.4 V), and 81.8% (4.5 V), respectively, when 1.0 wt % PFTB is incorporated into the standard electrolyte. The results of the physical characterization demonstrate that PFTB undergoes preferential decomposition on the cathode, forming a CEI membrane rich in F and B elements. These elements can effectively enhance the conductivity and stability of the CEI membrane. Therefore, adding PFTB to the electrolyte as an additive provides an economical and effective method for studying high-energy lithium batteries.

Lignin demonstrates significant potential for the efficient treatment of substantial quantities of radioactive iodine produced during the development of nuclear energy. However, its application has been hindered by issues such as poor solvent stability, low capture efficiency, and a limited range of applications. To cash in on the potential of lignin for iodine capture, we employed the electrospinning process to convert lignin from a powdered form to fibrous structures. This transformation not only mitigates the poor solvent stability associated with lignin but also broadens its applicability in iodine capture. Additionally, we implemented a method involving the preembedding of COF growth sites within lignin-based nanofibers. This approach facilitated the in situ growth of numerous COF structures within the lignin nanofibers, thereby enhancing the iodine capture capacity of lignin to a certain extent. Compared to pristine lignin, the lignin nanofibers with COF structures (L/TFB(X)NF) exhibited a marked improvement in their ability to capture radioactive iodine across various environmental conditions. The optimal iodine capture performance was observed in the L/TFB(1.2)NF, which achieved an iodine vapor capture of approximately 274.05 mg/g, an iodine capture of about 438.93 mg/g in n-hexane solution, and a capture of around 267.34 mg/g in aqueous solution. Furthermore, L/TFB(X)NF has been identified as a reusable ligninbased iodine trapping material. This study substantiates the hypothesis that bulk phase transitions, along with the incorporation of COF, can significantly improve the iodine trapping efficacy of lignin and expand its potential applications, presents novel insights into the development of lignin-based materials for iodine capture.

Phthalocyanine-based polymers are promising for energy storage due to their tunable redox-active sites, robust frameworks, and conjugated properties. However, the structure-property relationship between phthalocyanine content and electrochemical performance remains unclear, hindering the rational design of high-performance electrodes. In this work, the influence of phthalocyanine content was systematically investigated by controlling the molar ratio of N,N,N',N'-tetrakis(p-aminophenyl)p-phenylenediamine (TPPDA) to tetranitro-nickel phthalocyanine (NiPc-(NO2)4) (2:1, 1:1, 1:2). Three TPPDA-NiPc azo polymers were synthesized, revealing that higher phthalocyanine content enhanced structural integrity, azo bond density, and polymerization degree, while incorporating more reversible redox sites. The TPPDA-NiPc (1:2) electrode exhibited superior cycling stability and rate capability, delivering a maximum capacity of 970.5 mAh g-1 at 100 mA g-1- 453.6 and 238.4 mAh g-1 higher than the (2:1) and (1:1) electrodes, respectively. This performance stems from the optimized polymer network and shortened ion transport paths enabled by phthalocyanine incorporation.

Layered transition metal oxides are promising cathode materials for sodium-ion batteries due to their high specific capacity and low cost. However, the practical application of P2-type oxides is constrained by complex structural degradation mechanisms, particularly the P2-O2 phase transition and detrimental Na+/vacancy ordering during long-term cycling processes. To overcome these challenges, Rare Earth (RE) elements are innovatively incorporated into a high-entropy material configuration, yielding a P2-type high-entropy oxide (HEO; P2-Na0.72Mn0.66Ni0.22Y0.02Ce0.01Sc0.02O2), which is synthesized via the hydrothermal method. The inclusion of RE elements into high-entropy system effectively suppresses Na+/vacancy ordering and mitigates the Jahn-Teller distortion of Mn3+, thereby enhancing the structural stability and improving Na+ diffusion kinetics. The synthesized HEO cathode demonstrates excellent reversible sodium storage performance and rate capability, delivering a specific capacity of 113 mAh g-1 after 100 cycles at 1C, and achieving 81 mAh g-1 at a high current density of 10C, indicating remarkably enhanced performance. In situ X-ray diffraction and kinetics analyses demonstrate that the synthesized high-entropy system inhibited the P2-O2 phase transition while significantly boosting Na+ diffusion. This study elucidates the structure-performance relationship governed by RE elements and high-entropy engineering, providing valuable insights for developing high-performance sodium-ion batteries cathodes.

In order to solve the problems of insufficient adsorption electrolyte capacity and small specific surface area caused by the smooth surface and few pores of Super P spherical conductive particles, this work uses concentrated sulfuric acid (H2SO4) for surface etching of Super P conductive particles to explore the influence of different etching time on the micromorphology of SP conductive agent and the behaviors of LiNi0.5Co0.2Mn0.3O2 (NCM-523) batteries. After etched by concentrated H2SO4, the surface of SP conductive agent changes from “capillary” structure to fluffy “plush” structure, effectively improving the conductivity specific surface area of the conductive agent particles. Compared with the pristne SP-0H conductive agent, the batteries using 1.5% of concentrated H2SO4 etched SP-1H, SP-2H and SP-20H conductive agent have smaller EIS impedance value, larger area of CV curves, and smaller potential difference of the redox peaks. As a result, the initial charging/discharging capacities of SP-1H, SP-2H and SP-20H conductive batteries were 178.7/183.0, 187.6/183.9, 178.9/180.8 mAh/g with corresponding ICE of 102.4%, 98.0% and 101.1% respectively, which were much higher than the pristine SP-0H conductive battery (182.0/173.7 mAh/g with ICE of 95.4%). In addition, the SP-1H, SP-2H and SP-20H batteries also show significantly improved cycle performance and rate cycle capabilities, showing more superior comprehensive behaviors, which can provide a new modification insights for the exploration of new conductive agent in NCM-523 of high-performance lithium ion batteries.

To fully leverage the potential of lignin for capturing radioactive iodine, this study first involved cross-linking lignin using the nitrogen-rich cross-linking agent diethylenetriamine to obtain a modified product. Subsequently, we employed electrospinning technology to transform the modified product into a fibrous, thereby enhancing lignin's solvent stability and broadening its application scope. Notably, we introduced COF growth sites, para-phenylenediamine (Pa), into the spinning solution. Finally, the Pa-containing nanofibers were reacted with the COF growth ligand 1,3,5-tri(4-formylphenyl)benzene. This reaction facilitated the self-growth of TFB-DB COF on the fiber surface, ultimately yielding lignin nanofibers embedded with TFB-DB COF (L/TFP(X)NF). L/TFP(X)NF is regarded as a reusable iodine-capturing material. L/TFP(1.2)NF exhibited the highest performance, capturing approximately 475.0 mg/g, 4451.7 mg/g and 2191.2 mg/g of iodine in steam, n-hexane solution and aqueous solution, respectively. This study significantly enhanced the iodine capture efficiency of lignin through the synergistic effects of nitrogen cross-linking modification, fiber preparation, and COFs.

In this study, nylon-6/nylon-1012 (PA6/PA1012) composites with varying glass fiber contents were prepared via twin-screw extrusion. The compatibility of PA6/PA1012 was significantly enhanced by the incorporation of 1.5 % ethylene-octene copolymer-grafted-maleic anhydride (POE-g-MAH), as evidenced by SEM analysis demonstrating uniform dispersion of PA1012 within the matrix. The addition of glass fiber (up to 30 wt%) led to a substantial enhancement in tensile strength, flexural strength, and thermal deformation temperature by 153 %, 305 %, and 275 %, respectively, in comparison with pure PA6. The optimized composite exhibited a melt flow index of 26.7 g/10 min (260 degrees C/2.16 kg), which is significantly higher than that of ABS/ASA by 180 %, thereby enabling efficient molding of complex components. Moreover, the incorporation of anti-UV additives (UV-234/ HS-944) resulted in the retention of over 79.3 % of impact strength after 500 h UV ageing, surpassing the performance of conventional ABS/ASA. The composite's low equilibrium water absorption (1.20 %) and high dimensional stability (HDT= 210 degrees C) underscore its suitability for automotive rearview mirror brackets. This study presents a novel strategy for the development of high-performance composites through interfacial optimization and functional additive design.

In situ Schiff base reaction is utilized to grow phthalocyanine covalent organic frameworks (TFPB-NiPc) on carbon cloth (CC) to obtain the composite material TFPB-NiPc@CC, which is used as the anode for the binder and conductive agent free Li/Na-ion batteries with enhanced active materials loading. What is more, CC acts as an excellent conductive backbone while reducing the stacking effect of phthalocyanine frameworks (Pc-COFs), which enables TFPB-NiPc to realize the self-exfoliation effect during the in situ synthesis process. This strategy shortens the migration path of Li+, efficiently resulting in improving the migration rate of Li+ in the electrode. Consequently, the TFPB-NiPc@CC electrode not only shows improved electrochemical behaviors of high capacity and long cycle stability but also displays superior flexibility and folding stability. The specific capacity achieved by the TFPB-NiPc@CC electrode is 1090.2 mA h/g at 200 mA/g, and after 500 cycles, the specific capacity of the TFPB-NiPc@CC electrode can also be maintained at 994.5 mA h/g with a retention ratio of 91.2%, which are all much higher than those of the TFPB-NiPc electrode. Moreover, TFPB-NiPc@CC also shows a high specific capacity and stable cycling behaviors in Na-ion batteries. The strategies designed in this work provide new ideas and methods for preparing practical, high-performance flexible organic anode materials.

Precisely regulating the reaction pathway to produce desired products is a major challenge in electrocatalytic carbon dioxide reduction (eCO(2)R). In this paper, the wet chemical method was used to adjust the microenvironment between surface morphology and crystal planes of copper-based catalyst to accurately modulate eCO(2)R pathway, and to achieve the switching between methane (CH4) and ethylene (C2H4) products. In high concentration acidic CuCl2 etching solution for 80 s (Cu-3.6M-80s), the surface of copper foil formed a nano-groove structure with exposed Cu (111), which exhibited remarkable selectivity towards CH4 production. In contrast, when subjected to a low concentration acidic CuCl2 etching solution for 60 s (Cu-1.8M-60s), the copper foil surface exhibited a nanosheet/cube structure exposing Cu (220) and CuCl (111), resulting in the main product switched from CH4 to C2H4 with 57.03 % at 1.0 V versus reversible hydrogen electrode. In-situ attenuated total reflectance infrared and density functional theoretical calculations demonstrated that the Cu-3.6M-80s effectively enriched proton donation and lowered the energy barrier for *CO hydrogenation, while the Cu-1.8M-60s enhanced coverage of *CO intermediates, thereby promoting subsequent C-C coupling. This study presented a promising strategy for modulating the local microenvironment of catalysts, enabling precise control eCO(2)R pathway to achieve distinct target products.

A planar layered MOF material, PTCDA‐Ni, is prepared through a coordination reaction of PTCDA (3,4,9,10‐perylenetetracarboxylic acid) with Ni ions, and the PTCDA‐Ni is activated by solvent exchange activation with trichloromethane (TCM), acetone (AC), and co‐activation with AC and microwaves (AC&Mw) to obtain three MOFs materials ( PTCDA‐Ni@TCM, PTCDA‐Ni@AC, PTCDA‐Ni@AC&Mw ). The results show that the activated PTCDA‐Ni has a different degree of enhancement in the specific surface area, the size of the pore size, and its stacking aggregation compared with the unactivated PTCDA‐Ni . Meanwhile, the activation strategy can reduce the content of guest molecules in the pore structure, exposing more active sites and then improving the electrochemical properties. As a result, the capacity retention of PTCDA‐Ni electrode before activation is 60.8% after 200 cycles at a current density of 0.1 A·g −1 , while under the same conditions, the capacity retention of PTCDA‐Ni@TCM , PTCDA‐Ni@AC , and PTCDA‐Ni@AC&Mw electrodes are significantly improved to 92.1%, 96.9%, and 96.9%, respectively. The results of the GITT test and the CV curves at different scanning speeds similarly show that the activation strategy can increase the migration rate of lithium ions and further improve its electrochemical performance, which will open up a new idea for the design of anode materials for high‐performance LIBs.

Due to their inherent interfacial properties and structural instability, the cyclicity and reliability of singlecrystalline LiNi0.83Co0.07Mn0.1O2 layered oxides (SCNCM83) remain unsatisfactory in practical applications. Hence, we present a La/Al competitive doping strategy to address the instability of SCNCM83 cathodes, effectively mitigating side reactions and suppressing surface phase transitions. The La doping induces surface lattice reconstruction, transforming the layered structure into Li/Ni disordered layers while introducing robust La-O bonds. These bonds optimize local oxygen coordination and establish a reinforced crystal framework. Additionally, the formation of LiAlO2 enhances surface stability and charge transfer kinetics, further inhibiting parasitic reactions. Electrochemical testing reveals that the La/Al competitive doping SCNCM83 cathode delivers 94.1 % capacity retention after 150 cycles at 1C. In a practical application, a pouch-type full cell SCNCM83/ SCNCM83-2LA cathode with a graphite anode achieves over 1000 cycles within the 3-4.25 V range at 1C, retaining 93.5 % of its initial capacity. These results underscore the efficacy of competitive doping in stabilizing Ni-rich cathodes, offering a promising approach for developing durable, high-energy lithium-ion batteries.

Broadening the charging and discharging voltage window of high nickel cathode material NCM811 is the most expected method to improve the high specific energy density of batteries currently, yet the cathode-electrolyte interface (CEI) formed by the oxidized and decomposed products of carbonate-based electrolyte under high voltage are always so unsatisfied. Therefore, a voltage-stabilizer, TPFPB (Tris(pentafluoro)phenylborane), added into baseline electrolyte (1 M LiPF6 in EC:EMC:DMC=1:1:1 vol%) to promote the electrochemical performance of the battery at 4.5 V. The results interpret that the TPFPB-contained NCM811-Li half-cells exhibit high specific capacity (167.10 mAh/g), excellent capacity retention rate (CRR) (75.37 %), and high rate performance (173.3 mAh/g at 5C) during 4.5 V. Meanwhile, through the analysis of the physical characterization techniques. the Band F-rich interfacial layer, named as CEI film, existing at the interface between the cathode and the electrolyte, produced under 4.5 V, is superior, resulting in impeding the structural collapse of the cathode material and the continued dissolution of transition metal ions (TMn+) n + ) from the cathode material, as well as, ameliorate the electrochemical polarization of the battery, ultimately, it can stabilize the electrochemical performance of the battery under high voltage. Therein, the present work elucidate a new and substantial approach to enhance the high-voltage performances of rich-Ni cathode materials.

Although many researchers continue to pursue improved battery capacity, battery safety remains a major concern. The main cause of battery fires is the flammability of the currently available commercial organic liquid electrolytes, which are mainly composed of 1 M lithium hexafluorophosphate (LiPF6) and EC-containing carbonate solvents. Herein, a flame-retardant co-solvent tris(2,2,2-trifluoroethyl) phosphite (TTFP) was applied to improve the flame retardancy of a battery. It could improve the battery's discharging capacities at both 4.2 V and high cut-off voltage (4.5 V). Specifically, at a common voltage of 4.2 V, the cells' 100th discharge capacity without TTFP was 130 mA h g-1 by 0.2C with a capacity retention (CR) of 69%. In comparison, under the same conditions, the capacity of the 10% TTFP-containing cell was 162.3 mA h g-1 with a CR of 73.9%. This increase in the electrochemical properties of the cell is clearly due to the addition of TTFP. When charging and discharging at 2.75-4.5 V, the capacity of the battery with STD after 100 cycles at 0.2C was 118.7 mA h g-1, and the corresponding CR was 60.93%. Meanwhile, the discharged capacity of the battery containing 10% TTFP was 150.0 mA h g-1 with a corresponding CR of 65.39%. Through combustion test with and without the TTFP electrolyte, it can be concluded that the TTFP-containing electrolyte is difficult to ignite. This result indicates that TTFP can efficiently enhance the safety performance of the battery. Thus, the incorporation of TTFP can be beneficial to improve the flame retardancy of the electrolyte. Moreover, TTFP does not affect the electrochemical stability of batteries. Thus, the present work may provide a good direction for the next generation of high-performance and high-safety lithium-ion batteries. The incorporation of TTFP not only improves the flame retardancy of the electrolyte, but also does not affect the electrochemical stability of the battery, resulting in the formation of a superior B- and F-CEI layer.

Covalent organic frameworks (COFs) with abundant redox-active sites are prospective electrode materials for lithium-ion batteries (LIBs). Nevertheless, the sluggish lithium diffusion kinetics, lack of electrical conductivity, and low active point utilization rate of most known covalent organic framework materials limit their further applications. In this work, TACoPc-PDC/MnO2 composites are synthesized by efficiently exfoliating twodimensional covalent organic frameworks (TACoPc-PDC) via a strong oxidant intercalation strategy. The insitu growth of MnO2 nanoparticles is also realized during the exfoliation process. The MnO2 nanoparticles are similar to a "spacer", which allows the TACoPc-PDC to maintain their original few-layer structure in the continuous charging and discharging process, further preventing the re-aggregation of TACoPc-PDC. The prepared TACoPc-PDC/MnO2 exhibits a less-layered lamellar structure, leaving more active components exposed, which is more favorable for electrochemical performance. Compared with the bulk TACoPc-PDC, the exfoliated TACoPc-PDC exhibits higher capacities, stabler cycling performances, and more outstanding rate capabilities. The initial capacities of the TACoPc-PDC and TACoPc-PDC/MnO2 electrodes of the LIBs are 194 and 932 mAh/g, respectively, with a current density of 100 mA/g. After the continuous charging and discharging cycling process, the capacities are stabilized at 648 and 1100 mAh/g at 400 cycles. Even at the relatively high current density of 5 A/g, the TACoPc-PDC and TACoPc-PDC/MnO2 electrodes can realize high specific capacities of 67 and 307 mAh/ g. In addition, the cycling stability performance of the electrode materials has been further explored by performing SEM, XRD, and FTIR tests on the electrodes before and after cycling. Therefore, this work fully confirms that the exfoliation strategy using strong oxidant intercalation can provide an effective solution to reduce the aggregation of COFs electrode materials, effectively enhancing the utilization rate of active sites, ultimately achieving prominent energy storage performance.
