SOUTH 8 TECHNOLOGIES, INC. STTR Phase I Award, August 2019

The team at South 8 Technologies is the first to develop a novel and patented Liquefied Gas Electrolyte chemistry for rechargeable lithium metal batteries which meets these Air Force requirements. The proposed non-hazardous chemistry has already demonstrated world-record performance on the lithium metal anode (99.9% plating/stripping efficiency over hundreds of cycles) while maintaining high performance with conventional 4-V cathodes. The ultra-low viscosity and exceptional conductivity of the proposed electrolytes enable the use of thick cathodes while maintaining a high-power capability >1 C rate and will reach specific energy >425 Wh/kg.
