A nitrogen-rich covalent organic framework with high conductivity for high specific capacity Li-ion battery cathode
摘要
Rechargeable Li-ion batteries(LIBs)are the most vital energy storage devices[1].However,inorganic cathode materials typically are limited by their low theoretical capacities(＜400 mAh g-1)[2].In contrast,organic molecule cathode materials possess the advan-tages of low density,environmentally benignity,and safety[3-5].More importantly,the atomically precise molecular engineering of organic cathodes enables the high theoretical energy storage capacities through programmable π-conjugated organic molecules composed of multiple redox sites[6-8].The bright perspective of organic cathode materials has been demonstrated for sustainable LIBs.However,practical applications of organic molecule cathodes confront three major challenges including the easy dissolution in electrolyte,low conductivity,and poor ion mobility.
