Organic conjugated carbonyl compounds as electrode materials for lithium-ion batteries

Organic conjugated carbonyl compounds provide potential advantages such as high specific capacity, low-cost, and environmental benignancy. These merits make them promising candidates as electrode materials for next-generation green Lithiumion batteries (LIBs). The research progresses on organic conjugated carbonyl compound electrode materials with particular focus on the mechanism of electrochemical reaction of conjugated carbonyl compound electrode materials, small molecular conjugated carbonyl compounds and conjugated carbonyl polymers are reviewed. The new strategies to improve the performance of the electrode materials are pointed out, and the future development direction is given.
