A new class of aprotic organic electrolytes in which to cycle the lithium electrode has been developed. Blends of diethyl ether (DEE) and tetrahydrofuran (THF) incorporating LiAsF/sub 6/ have been found to afford Li electrode cycling efficiencies in excess of 98%. In addition, specular deposits of up to 10 C per sq cm may be plated from these systems. The kinetic stability of these blended electrolytes toward Li is thought to be due to the formation of a protective lithium ethoxide film.
