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.

Researchers suggest approach for boosting Li-S performance; conversion of Li2S to sulfur without polysulfides

Green Car Congress

Lithium-sulfur batteries are one of the most promising alternatives for next-generation high-energy-density batteries; however, one of the main obstacles to widespread commercialization that still needs to be addressed is the polysulfide shuttle mechanism between the two electrodes. the “ionic wiring”. Proposed reaction mechanism.

KAIST team develops stable, high-rate Li-S batteries using hierarchically porous titanium nitride

Green Car Congress

A KAIST research team has developed ultra-stable, high-rate lithium-sulfur batteries (LSBs) by using hierarchically porous titanium nitride (h-TiN) as a sulfur host. The hierarchical multiscale porous structure is still retained without any collapse after the conversion to h-TiN.
