DESIGN AND PERFORMANCE OF LI--AL/IRON SULFIDE CELLS FOR UTILITY ENERGY STORAGE AND ELECTRIC VEHICLES

The design, development, and testing of laboratory and engineering-scale Li--Al/iron sulfide cells at Argonne National Laboratory are described. The effort is directed toward the development of batteries suitable for utility energy storage and electric automobile propulsion. Results of testing of laboratory-scale cells of prismatic configuration (16 to 200 cm exp 2 electrode area) having electrodes fabricated by hot-pressing, electrochemical formation, or vibratory loading are presented. Prismatic cells were operated with specific energies of 115 W-h/kg at the 10-h discharge rate and specific powers of 140 W/kg at full charge and 100 W/kg at 50 percent discharge. Higher performance can be expected from improved cell designs which increase the ratio of electrode and active material weight to total cell weight, replacement of the ceramic fabric separators presently used by ceramic paper separators, and development of cells with lower electrical resistance. In order to involve industry early in the development effort, contracts to develop fabrication techniques for electrodes and cells were made by Argonne in 1975 with several industrial firms. Industry provides the fabrication development, while Argonne continues to develop the system to reach the program goals. This paper describes the choice of electrode fabrication techniques and cell designs for the second round of industrial contracts. The design and performance testing of the cells to date suggest that the technical program goals for both applications can be met. Testing of full-scale, industrially fabricated cells in battery configurations will be completed in the next two years. Full-scale batteries demonstrating technical and economic goals are expected in about 1981. 3 figures, 4 tables. (ERA citation 02:029883)
