An improved Li/SO₂Cl₂ cell

摘要

Studies have been carried out to improve the discharge ratecapability, reduce the anode corrosion and mitigate the voltage delay ofthe Li/SO₂Cl₂ cell. Addition of SO₂ orSO₂/SOCl₂ as the cosolvent improved thestorability and low temperature performance of Li/SO₂Cl₂ cells. Carefully purified electrolyte as well as addition of Ca²⁺ reduced the voltage delay of the cells. A new catalystprepared from polyacrylonitrile and cobaltous acetate increased the loadvoltage by more than 350 mW over that of an uncatalyzed cell, at 25mA/cm²
