The LiSOC12 battery has received attention because of its high theoretical energypower density. However, practical LiSOC12 cells have not provided the desired power density and have suffered from concerns with cell safety on discharge. In previous work, ECO has shown that the use of a TAA-type catalyst significantly improves the safety of the LiS0C12 cell at high rate. The objective of this Phase I program was to determne whether a stacked disk electrode configuration with TAA-catalyzed cathodes would meet a high power-density design goal. Under the program, the effects of cathode thickness, preparation pressure, electrolyte gap and solute concentration on stacked-electrode cell performance and capacity were measured. The results of the Phase I program included the demonstration of stacked-electrode cell performance and capacity at levels suitable to meet a design goal of 400 Wkg with high energy density. Further work in a Phase II program will be required to demonstrate in laser-sealed fully-packaged cells that the results of Phase I can be practically applied to provide a safe high-rate, energy-dense power source for military applications.
