Abstract
Abstract A nonaqueous cell utilizing a highly active metal anode, such as lithium, a solid (CFx)n cathode and a liquid organic electrolyte based on 3-methyl-2-oxazolidone in combination with a low viscosity cosolvent, such as tetrahydrofuran, and a metal salt selected from the group consisting of MBF4, MClO4 and MM''F6 wherein M is lithium, sodium or potassium and M'' is phosphorus, arsenic or antimony.
