The Effect of Additives on Lithium Cycling in Propylene Carbonate

Abstract

Deposition and discharge of lithium on an inert (nickel) substrate in 1M LiClO4/propylene carbonate (PC) has been studied as a function of plating and stripping currents, cycle number, and electrolyte composition. Water (<1200 ppm), nitromethane, and SO2 were found to enhance the cycling efficiency, which was relatively low in the dry electrolyte without additives. In all cases, marked deterioration in efficiency was noted after 10 to 20 repeated cycles corrosion was investigated. A mechanism of loss of efficiency during lithium cycling and also on open circuit stand has been formulated.
