PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

At the Spring 2015 Materials Research Conference in San Francisco earlier this month, PATHION presented two new derivative superionic solid-state electrolytes built upon LiRAP (Lithium-Rich Anti-Perovskite). Supported by an ARPA-E grant, LiRAP has proven to be a safe alternative compared to the liquid electrolytes used in most of today’s lithium ion batteries. Lithium sulfur. The second presentation described the use of a solid electrolyte in a sodium-ion battery cell.

New cathode material for Li-S batteries: sulfur-anchored azulene

Green Car Congress

A team of researchers from China and Germany have used azulene—a benzene-free and vinyl-free molecule—to polymerize with sulfur to create a cathode material for Li-S batteries. As described in an open-access paper in the RSC journal Chemical Communications ,the polymer exhibits high sulfur content and offers longer lifetime stability compared to pure sulfur, providing new protocols to develop new cathode materials for Li-S batteries. Batteries Li-Sulfur
