Electrolyte/separator system, useful for producing electro-chemical energy-storage systems e.g. lithium metal batteries, comprises electrolytes comprising base component, ionic liquid, water, additive, lead salt and ceramic separator

摘要

Electrolyte/separator system comprises electrolytes comprising: a base component; at least one ionic liquid containing imidazole compound (I), with a melting point of less than 100[deg]C; 0-70 ppm (m/m) water; 0-10 wt.% of an additive; 0.25 mol of a lead salt that is soluble in the base components; and a ceramic separator. Electrolyte/separator system comprises electrolytes comprising: a base component; at least one ionic liquid containing imidazole compound of formula (I), with a melting point of less than 100[deg]C; 0-70 ppm (m/m) water; 0-10 wt.% of an additive; 0.25 mol of a lead salt that is soluble in the base components; and a ceramic separator. R, R 1alkyl group. An independent claim is also included for a lithium ion battery comprising the electrolyte/separator system. [Image].
