Organic active materials in rechargeable batteries: Recent advances and prospects

Organic electrode active materials are widely used in the research of electrochemical energy storage devices due to their advantages of low cost, friendly environment, strong sustainability, flexible design and high electrical activity. Although organic active materials (OAMs) are widely studied in organic and aqueous batteries, there are still some challenges to overcome before large-scale commercialization. In this paper, the reaction mechanism of OAM was reviewed, and the application of OAMs including small molecule, polymer and coordination compound in organic battery and aqueous battery and the strategy of improving electrochemical performance were introduced. Finally, the key problems and future research directions of the application of OAMs in batteries were put forward.
