MIT: hybrid cathodes could boost energy capacity of lithium-sulfur batteries

Green Car Congress

Anion-redox lithiumsulfur (Li–S) is one of the most promising conversion battery chemistries with high theoretical cathode energy density of 2,600 Wh kg -1 based on the weight of Li 2 S, S 8 + 16 e? These cathodes can maintain their structure and dimensions while incorporating lithium atoms into their crystalline structure.

China team develops new high-performance cathode for Li-sulfur batteries

Green Car Congress

Jian Liu and Prof.Zhongshuai Wu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have developed Fe 1-x S-decorated mesoporous carbon spheres as a cathode material for lithium-sulfur batteries. This further causes low capacity and stability of lithium-sulfur batteries.
