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? But that limitation is “not the cathode’s problem”; it has to do with the overall cell design, and “we’re working on that,” Li says.
