Electrolytes for Lithium Ion Batteries
High-conductivity alkali-metal-ion containing electrolytes comprising viscous liquid or rubbery solid alkali metal salts which obtain conductivity by the domainate motion of cation ions which, when produced in accordance herewith, remain freely mobile at low temperatures. One embodiment relates to molten alkali metal salt electrolytes comprised of one or more alkali metal salt compositions which are substantially non-crystalline and have glass transition temperatures below room temperature.
