Cover Story: Layered lithium-rich manganese cathodes have attracted increasing attention due to their high reversible capacity and high operating voltage. Nevertheless, the development of layered lithium-rich manganese cathodes for commercial batteries is hampered by considerable capacity and voltage attenuation, poor rate performance, and significant reversible capacity loss during the first charge and discharge stages. Effective strategies have been adopted to address these drawbacks, such as ion doping, surface modification and nanostructure morphology. In this work, Li1.2Mn0.54Ni0.13Co0.13O2 nanotubes with conductive polymer PPy coating were investigated. The electrochemical measurements demonstrate that Li1.2Mn0.54Ni0.13Co0.13O2 nanotubes coated with PPy can significantly improve electrochemical performance. View this paper
