Researchers at MIT and in China are proposing a new class of dense intercalation-conversion hybrid cathodes by combining intercalation-type Mo 6 S 8 with conversion-type sulfur (HMSC) to realize a Li–S full cell. Typical sulfur cathodes are made up of 20 to 30 percent carbon, he says, but the new version needs only 10 percent carbon.

Researchers at Jiangsu Normal University in China have devised a boron-doped carbon-sulfur (BCS) aerogel with consecutive “core-shell” stuctures as a binder-free cathode for lithium-sulfur batteries. Good porous structures of BCS aerogel can provide sufficient space for the expansion of active sulfur.

Researchers from Central South University in Changsha, China, have developed a separator with a nitrogen-doped porous hollow carbon sphere (NHC) coating for use in Li-S batteries. The NHC-decorated separator enormously improves the utilization of active material and enhances electrochemical performance. 2015.09.067.
