Abstract :
Studies have been carried out to improve the discharge rate capability, reduce the anode corrosion and mitigate the voltage delay of the Li/SO2Cl2 cell. Addition of SO2 or SO2/SOCl2 as the cosolvent improved the storability and low temperature performance of Li/SO2Cl2 cells. Carefully purified electrolyte as well as addition of Ca 2+ reduced the voltage delay of the cells. A new catalyst prepared from polyacrylonitrile and cobaltous acetate increased the load voltage by more than 350 mW over that of an uncatalyzed cell, at 25 mA/cm2
