Abstract
Abstract A nonaqueous cell utilizing a highly active metal anode, such as lithium, a solid CuO cathode and a liquid organic electrolyte consisting essentially of 3-methyl-2-oxazolidone in combination with a low viscosity cosolvent, such as tetrahydrofuran, and a metal salt selected, for example, from the group consisting of MSCN, MCF 3 SO 3 , MBF 4 , MClO 4 and MM'F 6 wherein M is lithium, sodium or potassium and M' is phosphorus, arsenic or antimony.
