Rechargeable Li-ion full batteries based on one-dimensional Li-rich Li1.13Mn0.26Ni0.61O2 cathode and nitrogen-doped carbon-coated NiO anode materials

To meet the increasing requirements of lithium-ion batteries (LIBs) as energy sources for mobile electronic devices and electric vehicles, great efforts are being made to develop cathode and anode materials with high specific capacity and lifetime stability. Herein, we report a Li-rich one-dimensional (1D) Li1.13Mn0.26Ni0.61O2 (0.3Li(2)MnO(3)center dot 0.7LiNiO(2), LMO@LNO) cathode and a nitrogen-doped carbon-decorated NiO (NC@NiO) anode material prepared from 1D Ni(OH)(2) nanowires (NWs) for application in full LIBs. The as-prepared 1D Li-rich LMO@LNO cathode displays a high discharge capacity (184.4 mA h g(-1)), high coulombic efficiency (73.9%), long-term cyclability, and good rate performance in comparison with pristine LiNiO2 (LNO). Moreover, the 1D NC@NiO composite anode exhibits a high discharge capacity (914.5 mA h g(-1)), high coulombic efficiency (76.8%), long cycling life, and better rate performance, as compared with bare NiO. A full LIB consisting of the nanostructured Li-rich LMO@LNO cathode and the NC@NiO anode delivers a high capacity of over 167.9 mA h g(-1) between 4.0 and 0.1 V. These enhanced electrochemical characteristics suggest that the full LIB configuration with 1D Li-rich LMO@LNO and NC@NiO composites holds promise as a next-generation secondary battery platform.
