SELF-ASSEMBLED 3D GRAPHENE OXIDE ELECTRODES FOR LITHIUM-ION BATTERIES

摘要

Large-scale energy storage applications, such as renewable energy storage and smart-grid, drive the development of more sustainable and affordable organic electrodes. Recently, it has been shown that oxygen functional groups on the surface of nano-carbon materials can react with Li-ions reversibly at ～3 V vs Li, proposing these organic materials as new rising positive electrodes for the Liion batteries. As the redox reactions primarily take place on the surface of the nano-carbons, with no intercalation reactions involved, these electrodes generally show both high power and high energy density, and good cycling stability.
