Huawei Watt Lab develops graphene-assisted high-temperature Li-ion batteries

Green Car Congress

Huawei researchers recently unveiled what they said was the first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures. The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as ordinary Li-ion batteries.

Tokyo researchers discover structure and transport properties of intermediate stage in Li-ion batteries; may shorten charging time

Green Car Congress

Researchers at the University of Tokyo and Tokyo Institute of Technology have discovered the structure and transport properties of an “intermediate state” in LiFePO 4 lithium-ion batteries. Lithium ions distribute themselves so as not to disturb this striped pattern. The findings were contrary to expectations. —Prof.

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). PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery.
