Oxocarbon organic compound cathode materials for lithium secondary batteries

The organic compounds as the cathode materials of lithium secondary batteries have attracted wide attenttion because of their high specific capacity, abundant resource, environmental frienliness and safe system in recent years. The progress in oxocarbon organic cathode materials, including quinies, acid anhydrid, nitrocmpound, etc is summarezed. Their structures, electrochemical properties and the discharge and charge machanism are introduced. Meanwhile, their advantages and disadvanges are discussed.The discharge potential and specific capacity of organic cathode material are also compared. Finally, the future research focuse for the oxocarbon cathode materials are proposed.
