Research progress in polymer cathode materials for Li-ion battery

The inorganic sulfides,organic sulfides and poly radical were used as cathode materials in Li-ion batteries and they had many advantages such as high energy capacity,rich sources and friendly to environment.The development of polymer cathode materials in recent years were introduced.In the future development of high specific energy Li-ion batteries,the studying of conjugated organic polysulfide and poly radical cathode materials should be strengthened.
