The dependence of the electrochemical characteristics of a layered cathode material containing LiNi0.5Mn0.3Co0.2O2 on the method for applying a protective layer of nanoparticles of the lithium-conducting material Li1.3Al0.3Ti1.7(PO4)(3) with a NASICON structure to its surface has been studied. The surface modification has been found to improve the capacity retention in prolonged charge/discharge cycling (up to 15%) and to allow fast charge/discharge processes. The possibility of using a composite electrolyte consisting of a porous ceramic matrix of aluminum-substituted lithium titanium phosphate Li1.3Al0.3Ti1.7(PO4)(3) with a transition layer of liquid electrolyte LP-71 has been shown. The use of a thick composite solid electrolyte results in a slight reduction (similar to 5-7 mAh g(-1)) in initial capacity compared to laboratory cells with the widely used Celgard 2400 separator impregnated with liquid electrolyte. Laboratory cells assembled with a composite electrolyte showed higher stability during charge/discharge cycling: after 80 deep charge/discharge cycles, the capacity reduction was similar to 12% for cells with a composite electrolyte, while for the reference cell it was similar to 23%.

We have developed composite paint based on graphite, carbon black and some other not expensive components, which can be used as a clay court for sustainable buildings and electronic devices. This paint can reduce sufficiently the problem, which is related to the effects of electromagnetic radiation (EMR) on human health. Cellular and radiotelephones, as well as their broadcast antennas, especially which use of the 5G, 6G communication system, may pose a high risk of cancer, reproductive disorders, memory, cellular stress, neurological and mental disorders. The medical disorders are already often experienced by servicemen working at radar stations, observation posts and other similar facilities associated with high-frequency EMR. The effect of EMR is especially dangerous for children of preschool and school age, so, it is necessary to use similar paints first of all for such buildings.

The effect of EMR is especially dangerous for children of preschool and school-age, so, it is necessary to use similar paints first of all for such buildings. It is also necessary to note the significant impact of EMR on electronic equipment. First of all, this is a well-known problem of providing the so-called "electronic compatibility", when simultaneously operating different electronic equipment (e.g., thermal imager and radio transmitter) interfere with each other. A number of scientific developments have been implemented and work is underway under the NATO SfS international grant in this area.

Based on both the economic and environmental points of view, processing used lithium-ion batteries (LIBs) is of great importance. The valuable components contained in LIB (cathode, anode and current collectors) generate high interest in solving the problem of resource deficiency and reducing environmental destruction due to overexploitation. The starting anode material extracted from a used lithium iron phosphate battery is a mixture of graphite, acetylene carbon black, and polymer binder. Reusing this material in lithium batteries without additional cleaning is impractical owing to poor electrochemical characteristics and the presence of impurities. To achieve effective regeneration, the recycled anode material is first treated in a nitric acid solution to remove copper foil and lithium ions with electrolyte interaction products formed during battery operation. The next step is heat treatment of the material, which allows the removal of acetylene soot and polymer glue binder. The tests showed sufficiently high values of the specific capacity of recycled graphite (~330 mA h g-1 at 0.1 C), which are comparable to commercial materials and meet the requirements of reuse.

Мета дослідження: Встановлення впливу модифікаторів - гідратованого діоксиду цирконію та його композиту із вуглецевими наноточками - на розділову здатність полімерних мембран (перенос іонів та закономірності фільтрування води і розчинів білків) для подальшого використання мембран із найкращими властивостями у процесах концентрування білкових компонентів із рідин біогенного походження. Методи дослідження: Сканувальна електронна мікроскопія (дослідження морфології мембран), гравіметричний (визначення вмісту ZrO2 у полімері), кондуктометрія (вміст солі у водних розчинах), потенціометрія (вимірювання мембранного потенціалу), спектрофотометричний (концентрація білку у пермеаті). Результати: Мікрофільтраційні мембрани (полівініліденфторидну та поліамідну) модифіковано гідратованим діоксидом цирконію, а також його композитом із вуглецевими наноточками, розмір яких становить 8–12 нм. Тестування мембран при фільтруванні води показало, що найменший гідродинамічний опір, який становить (0.48–3.77)´1012 м-1 виявляють полівініліденфторидні мембрани - як вихідна, так і модифіковані. При фільтруванні розчину бичачого сироваткового альбуміну показало, що найбільшою стійкістю до органічних забруднювачів та найвищою розділовою здатністю характеризується мембрана, модифікована композитом: при цьому затримується 100% білку. Цю мембрану використано для одержання білкового концентрату молочної сироватки. При цьому утворення осаду відбувається на її зовнішній поверхні. Для ідентифікації вуглецевих наноточок в інкорпорованому композиті запропоновано непрямий метод, який передбачає вимірювання мембранного потенціалу та вивчення дифузії солі (1,1-зарялного електроліту). Розраховано коефіцієнти дифузії іонів. У випадку полівініліденфторидних матеріалів, що містять одно- та двокомпонентний модифікатори, ці значення становлять відповідно 7´10-12 та 6´10-13 м2с-1 для іонів Na+. Отже, вуглецева складова зменшує коефіцієнти дифузії на порядок. Висновки: Введення до пор мікрофільтраційних мембран двокомпонентного модифікатору, що містить вуглецеві наноточки, дозволяє покращити затримуючу здатність мембран та підвищити їх стійкість до органічних забруднювачів. Мембрани можуть бути використані для переробки рідин біогенного походження.

Мета. Дослідження впливу параметрів одно- та двокомпонентного вуглецевого наповнювача на електропровідність акрилового полімерного композиту у вигляді тонкого покриття. Методика. Приготування зразків композитів відбувалось на швидкісному міксері занурюваного типу. Розміри та форму часточок наповнювачів, а також структуру полімерних композитів досліджували у відбитому світлі за допомогою мікроскопу МБИ-15У42. Електропровідність отриманих зразків вимірювали згідно стандартів ASTM D257-07 та ASTM F1711-96 відповідно до значень поверхневого опору зразків. Результати. Визначено пороги перколяцій для композитів наповнених однокомпонентним наповнювачем – технічним вуглецем, графітом КГП-С1, вуглецевим волокном. В результаті проведених експериментів показано, що перколяційна поведінка провідності полімерних композитів, наповнених однокомпонентним наповнювачем, пов'язана з морфологією відповідного наповнювача та внутрішньою структурою, яку він утворює при взаємодії з полімером. Синтезовані полімерні композити з двокомпонентними наповнювачами КГП-С/технічний вуглець, вуглецеве волокно T300/технічний вуглець, і різним співвідношенням вуглецевих матеріалів та загальним наповненням в композиті 50–70 об. % показали синергетичний ефект електропровідності при певному співвідношенні компонентів наповнювача. Наукова новизна. Встановлено вплив співвідношення складових вуглецевого двокомпонентного наповнювача на електропровідність акрилового полімерного композиту. Практична значимість. Визначено оптимальну пару вуглецевих наповнювачів, їх вміст та співвідношення двокомпонентного наповнювача в акриловому полімерному композиті. Отримані композити можуть бути використані для виготовлення електропровідного полімерного покриття.

Мета: Дослідження впливу фізичних властивостей природних графітів на електропровідність полімерних покриттів. Методика: Геометричні параметри частинок різнодисперсних графітів вивчалися методами оптичної та електронної мікроскопії. Зміна просторової електропровідності графітових порошків під дією зовнішнього навантаження визначалася за допомогою спеціально виготовленої комірки. З урахуванням анізотропних фізичних властивостей кристалів графіту при виготовленні композитів у полімерне зв’язувальне додавався диспергований технічний вуглець. Диспергування здійснювалось за допомогою ультразвуку в спиртовому середовищі. Як зв’язувальне дисперсних компонентів використовувався 10%-ий розчин полівінілбутиралю в етанолі. Товщина композиту на твердій поверхні задавалася за допомогою аплікатора. Поверхнева електропровідність фіксувалася чотирьохелектродним методом. Результати: Досліджена залежність поверхневої електропровідності полімерних композитів від розмірів, форми та полідисперсності частинок графіту. При отриманні полімерних покриттів на основі графіту лакофарбовим методом виникає суттєва орієнтація двохвимірних частинок мінералу, що суттєво впливає на просторову електропровідність композита. Фактором, який обмежує електропровідність полімерних покриттів на основі крупнодисперсних графітів, є мікропори і дрібні тріщини, обумовлені низьким ущільненням таких частинок і великим об’ємом етанолу в 10%-му розчині полімерного зв’язувального. Ультразвук за певних умов приводить до розшарування частинок графіту, що сприяє підвищенню електропровідності композитних покриттів. Наукова новизна: Установлено, що зі збільшенням розмірів і зменшенням полідисперсності частинок лускатого графіту поверхнева електропровідність полімерного покриття зростає. Додавання до композиту дисперсних вуглецевих чи неорганічних добавок знижує дану електропровідність. Практичне значення: Зростання поверхневої електропровідності полімерних композитів у екрануючих пристроях сприяє ефективності захисту людини та електроніки від негативного впливу електромагнітного випромінювання.

This paper considers the dependence of electrical conductivity of a graphite-based composite material on the size, polydispersity, shape and orientation of the graphite particles. The study reveals that these factors exert a significant effect on the conductivity of composite materials. It also shows that Ukrainian graphites can be used for manufacturing lithium-ion battery electrodes and composite screens to provide shielding against electromagnetic radiation.

Models are proposed for describing unequal accessibility of charge–discharge processes in battery active materials (AMs) at different hierarchical levels of the system: in an individual AM grain, in the thickness of porous electrode, and along the height and surface of the battery electrodes. Criteria are formulated for selection of systems of a “sufficiently small size”, in which the unequal accessibility could be ignored and which can be used to determine required parameters of the model from experiment.

ENERGY FACILITIES: MANAGEMENT AND DESIGN AND TECHNOLOGICAL INNOVATIONS Today, more and more attention is paid to non-traditional rechargeable sources of electric current, which are able to quickly charge and discharge (in a few seconds or minutes), have high power (kW/kg) and a long service life (tens of thousands of charge-discharge cycles). Such current sources include electrochemical capacitors (EC), which in the special literature are called supercapacitors, ultracapacitors, ionistors, or molecular storage devices.The principle of operation of such current sources is based on their ability to store and release electrical energy at a given time through the internal redistribution of electrolyte ions in a double electric layer (DEL). The rate of redistribution of ions in the DEL is several orders of magnitude higher than the rate of ion transfer through the “electrode-electrolyte” phase boundary during classical redox transformations in batteries. That is why ECs are non-traditional current sources, they have significant advantages over batteries in terms of their specific power, the rate of charge-discharge processes and service life, although they are inferior to batteries in terms of their capacity and energy density. Particular attention has been paid to EC in connection with the start of production in many countries of the world of environmentally friendly cars and buses with electric motors that require high power at the time of engine start. In addition to being used in transport, ECs are widely used in military and space technology, in energy storage systems at peak loads, for regulating wind generator turbines, etc.The production of electrochemical capacitors requires fairly large capital investments. This is due to the requirements for the environmental friendliness of the production itself, where a significant amount of costs is spent on ensuring safe working conditions for personnel, on capturing harmful substances and their disposal. That is why the issue of developing EC to reduce the cost of production through the use of new materials and the improvement of technological processes becomes especially relevant.The main scientific research in recent years in the field of EC has been associated with the study of new electrochemical systems, electrode materials and electrolytes. To a certain, but insufficient extent, attention was also paid to the improvement of the technology of combining the active material and the current collector. Even less research work is related to the development of environmentally friendly technologies for the production of composite active materials for capacitors, although the development of these components can potentially provide high electrical performance of capacitors and significantly reduce the cost of their production. These circumstances put forward the research and development of environmentally friendly methods for obtaining composite materials for electrochemical capacitors into the category of complex, but relevant scientific and technical problems. ------------------------------------------------------------------------------------------------------------------ How to Cite: Khomenko, V., Chernysh, O., Barsukov, V., Tverdokhlib, V., Berezovskij, A., Slobodianyk, V.

The present manuscript reports on optimized formulations of alcohol-based conductive paints for electromagnetic interference shielding (EMI), which can ensure compatibility and reduce the visibility of electronic equipment, as a continuation of our previous work in this field, which examined water-based formulations for other applications. Graphite, carbon black, graphene, Fe3O4, Fe ore, and PEDOT:PSS in various ratios and combinations were employed in an alcohol base for developing homogeneous paint-like fluid mixtures that could be easily applied to surfaces with a paintbrush, leading to homogeneous, uniform, opaque layers, drying fast in the air at room temperature; these layers had a reasonably good electrical conductivity and, subsequently, an efficient EMI-shielding performance. Uniform, homogeneous and conductive layers with a thickness of over 1 mm without exfoliations and cracking were prepared with the developed paints, offering an attenuation of up to 50 dB of incoming GHz electromagnetic radiation. The structural and morphological characteristics of the paints, which were studied in detail, indicated that these are not simple physical mixtures of the ingredients but new composite materials. Finally, mechano-climatic and environmental tests on the coatings demonstrated their quality, since temperature, humidity and vibration stressors did not affect them; this result proves that these coatings are suitable for commercial products.

The present work regards the development of paint-like composites based on mixtures of carbon materials with magnetite in polyvinyl butyral matrix, and the investigation of the dependence on the electrical characteristics and the frequency of their electromagnetic shielding properties. It was found that high electromagnetic shielding effectiveness requires not only the presence of a high content of carbon components in the composite, but also the absence of an agglomeration of filler particles. Using these paint-like materials, a shielding effectiveness of up to −35 dB of UHF radiation can be obtained. A combination of fillers based on carbon-graphite materials of different morphology and magnetite was found to enhance shielding efficiency.

The development of materials offering electromagnetic interference (EMI) shielding is of significant consideration, since this can help in expanding the lifetime of devices, electromagnetic compatibility, as well as the protection of biological systems. Conductive paints used widely today in electromagnetic interference (EMI) shielding applications are often based on organic solvents that can create safety issues due to the subsequent environment problems. This paper concerned the development of eco-friendly conductive water-based paints for use in EMI-shielding applications. Graphene nanoplatelets, polyaniline emeraldine (PANI) doped with poly(styrene sulfonic acid) (PSS) or HCl or HBr and poly(3,4-ethylenedioxythiophene) poly(styrene sulfonic acid) (PEDOT:PSS) in various ratios were employed in a water base for developing the paints. The target was to develop homogeneous water-based paint-like fluid mixtures easily applied onto surfaces using a paint brush, leading in homogeneous, uniform, opaque layers, draying fast in air at room temperature, and having quite good electrical conductivity that can offer efficient EMI-shielding performance. The results of this parametric trial indicated the optimum compositions leading in paints with optimized properties that can result in uniform, homogeneous, and conductive layers up to a thickness of over 500 μm without deformation and cracking, offering attenuation of up to 60 dBs of incoming GHz electromagnetic radiation. In addition, the structural and morphological characteristics of these paints were studied in detail.

LiNi0.6Co0.2Mn0.2O2 (NMC 622) cathode material is widely used for lithium-ion batteries. The effect of the method of creating a protective layer of Li1.3Al0.3Ti1.7(PO4)3 (LATP) on the electrochemical characteristics of commercial cathode material NMC 622 was investigated. It was found that both methods of LATP coating did not affect the crystal structure and morphology of NMC 622. The prototypes of Li-ion batteries with a cathode based on modified NMC 622 are characterized by significantly higher stability of capacitive characteristics during long charge/discharge cycling, compared with prototypes of Li-ion batteries based on the pristine cathode material. In addition, the protective layer of LATP, applied by the sol–gel method, can significantly increase the capacity of the cathode material NMC 622 at the high current density and reduce the capacity drop during the continuous charge/discharge cycling. Creating a protective layer of LATP via sol–gel method is an effective way to improve the electrochemical characteristics of cathode materials such as NMC 622.

Future technologies for organic photovoltaics include self-organization and self-assembly. Heterocyclic amines, namely sodium sulfacyl, clonidine, and cyanocobalamin, were deposited on four types of carbon-on-paper substrates by the self-organization assembly method. Each organic film was deposited in the chemical bath for 10, 20, 40, 60, and 90 min. Carbon substrates were thin layers of carbon composites deposited on Maestro paper. Compositions of carbon films of thicknesses about 20 mcm included graphitized carbon black “PureBlack@”and graphite “KGPS-1” as the permanent components, as well as activated carbon, magnetite, nanotubes, and needle graphite DBX-010 as variable components. Polyvinyl butyral (PVB) served as a binder for all of these composites. Morphological features of organic-carbon hybrids were investigated using optical microscopy MII-4 of 500 nm resolution with a SLR camera. The injection properties of the obtained hybrids were studied on standard equipment for current–voltage characteristics measuring. The thin organic films demonstrated the possibility of self-organization on various carbon substrates. The best grid morphology was determined for the optimal deposition time between 20 and 40 min with circular-type cells. The best injection properties correlated with the best morphology. These heterocyclic amines-on-carbon hybrids are promising structures for the formation of non-expensive and easily-fabricated solar cells.

The use of new polymeric binder materials on the water and alcohol base in electrochemical power sources is still a relevant and present-day issue. Electrochemical capacitor performances are influenced by binder types and contents in the electrodes. The electrochemical performances of activated carbon based electrochemical capacitors with different polymeric materials such as polyvinylbutyral, polyvinylpyrrolidone, polyvinylflouride and polytetrafluoroethylene were investigated by cyclic voltammetry, galvanostatic charge - discharge and electrochemical impedance spectroscopy. The results obtained can be used for the creation of a new production technique of electrodes and decrease in the electrochemical capacitors prime cost.

Purpose of the research: studying the effect of addition of carbon nanosized modifier graphene oxide on the formation of a porous film during the electrochemical oxidation of aluminum.Methods: UV-VIS spectra of graphene oxide suspension were obtained using a spectrophotometer, the thermogravimetric characteristics of anodized alumina were determined using a thermal analyzer, the surface characteristics were determined by the low-temperature nitrogen sorption-desorption method, the surface was calculated by the BET method, the morphology and ultrastructure of the surface were determined using electron microscope.Results: the possibility of using carbon materials for the electrochemical oxidation of aluminum was shown. The obtained electron micrographs indicate the effect of the inserted carbon modifier (graphene oxide) on the morphology of resulting oxide. As a result of this process we observe the formation of the cellular surface of the aluminium oxide with smaller pores compared with sample after synthesis without the modifier.It was shown that the addition of graphene oxide (0.25%) in the oxalic acid (0,3М) electrolyte effects on the stability of the anodizing process, the specific surface area of the sample of anodized aluminum synthesized with graphene oxide is determined as 35.5 m3/g, and it is three times higher than sample without modifier. According to sorption studies, it could be noted that the presence of nanosized graphene oxide in oxalic acid electrolyte leads to the formation of honey-comb pores with a smaller radius (22 nm), while the total volume of micropores increases. The obtained results allow us to conclude that graphene oxide as modifier is promising material for the preparation of anodized aluminum oxide matrices. In the future, these matrices could be used in processes of solutions and gases separation.Conclusions: The addition of graphene oxide into the electrolyte changes structure of porous anodized aluminum oxide and has shown the possibility of controlling the porosity of films.
