Advances in thin film technology could lead to safer and more powerful lithium based batteries, U.S company PATHION claims.
The proposition comes as the Californian company described the role of its Lithium-Rich Anti-Perovskite (LiRAP) in a solid-state lithium sulphur electrolyte.
The research was presented at the Spring 2015 Materials Research Conference in San Francisco.
The privately held company has synthesised a sulfur cathode, which achieves specific energy levels up to 800Wh/kg when used in combination with the electrolyte, it claims.
Along with increased energy, solid-state electrolytes have low expansion, no out-gassing, and eliminate dendrite growth between anode and cathode. All of these can cause lithium-ion batteries to explode, especially toward end of life.
Secondly the company has unveiled details of sodium-ion battery cells, which substitute a liquid electrolyte with – PATHION’s solid-state LiGlass.
LiGlass exhibits ultrafast ionic conductivities at up to 200°C – which the company claims can lead to energy densities in excess of 1,000Wh/kg.
LiGlass has been replicated in the labratory at the University of Texas.
PATHION has an exclusive worldwide license for LiRAP and has acquired rights to key advanced materials under a cooperative research development agreement with Los Alamos National Laboratories.
