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

Green Car Congress

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. Intercalation type cathodes, which use compounds such as lithium cobalt oxide, provide a high volumetric energy density.

Vertically aligned sulfur-graphene nanowall cathodes for Li-sulfur batteries deliver high capacity and rate performance

Green Car Congress

1 , more than 5x that of commercial Li-ion batteries; sulfur is abundant, nontoxic, and inexpensive), practical application has been hampered by a number of challenges. S batteries, one effective strategy is to confine sulfur and polysulfides into carbonaceous matrix and meanwhile improve the electrical conductivity of overall electrodes.
