主 题：lithium batteries organic electrode materials redox chemistry intermediates phase transitions
摘 要：Organic electrode materials have attracted much attention for lithium batteries because of their high capacity,flexible designability,and environmental friendliness.Understanding the redox chemistry of organic electrode materials is essential for optimizing electrochemical performance and designing new molecules.This review aims to summarize the redox chemistry of different organic electrode materials in lithium batteries,including carbonyl compounds,conductive polymers,organosulfur compounds,organic radicals,imine compounds,compounds with superlithiation ability,and azo compounds.The discussions are focused on the evolution of their molecular and crystal structures during discharge/charge processes utilizing various characterization approaches.To date,carbonyl compounds based on the conversion between C=O and C-OLi have been proven to be one of the most promising organic electrode materials for lithium batteries.Future works should pay more attention to the detection of redox intermediates through operando techniques and the further combination of theoretical calculations.This review provides insights into the redox chemistry of organic electrode materials in lithium batteries.
