A small amount of thiophene or ethylene dioxythiophene (EDOT) is introduced into the liquid electrolyte of lithium-ion cells as an additive. These organic additives are electrochemically oxidized to form a thin conductive polymer film on the surface of the cathode at high potential. With the liquid
