This project evaluates the potential of a new class of cathode catalysts to improve the safety and the performance of high rate Li/SOCI2 batteries. A safer Li/SOCI2 battery with improved capacity, rate capability and voltage delay provides a practical long life energy/power density lithium-based power source. The major objective of the program is to determine whether commercial high rate Li/SOCI2 batteries with catalyzed cathodes have improved safety under pulse load, short circuit and forced over discharge when operated in the temperature range of 0 C to 75 C. A second objective is to forecast the safety, reliability and producibility of larger battery systems. The major advantage of the use of the catalyzed cathode is the change in reaction mechanism away from S02 formation without affecting battery cost. The program approach is to heavily stress high rate AA-size catalyzed-cathode batteries supplied by two commercial suppliers. Battery temperature change, cell and anode performance, and reaction products will be identified.
