A Safe, High-Power-Density Lithium Battery.
Abstract
The Li/SOC12 battery has received attention because of its high theoretical energy/power density. However, practical Li/SOC12 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 Li/S0C12 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 W/kg 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.
