Summary
This report presents highlights for 1975 of Argonne National Laboratory's program on the development of lithium/metal sulfide batteries. The intended applications for these high-performance batteries are energy storage on utilities and electric-vehicle propulsion. The battery cells have negative electrodes of a lithium--aluminum alloy and positive electrodes of FeS/sub 2/ or FeS, and operate at 400 to 450/sup 0/C. During the past year, a new cell design was adopted; the cells are prismatic and are operated with the electrodes in a vertical orientation. Conceptual designs for two types of batteries have been completed: an electric-vehicle battery that could be installed under the hood of an automobile and a load-leveling battery for testing in the Battery Energy Storage Test Facility. Promising methods for fabricating electrodes include loading of powders into porous current collector structures, incorporation of active materials into a carbon-bonded matrix, and hot-pressing of powders. Receiving major attention is a design in which cells are assembled in the uncharged state. Engineering-scale Li-Al/FeS cells of this type have achieved specific energies of 100 W-hr/kg and peak specific powers of 130 W/kg. Cell chemistry studies and materials studies are conducted to provide support to the cell effort. A method was devised for preparing lithium sulfide in a suitable form; studies of cell overcharge reactions led to the establishment of optimum cell cutoff voltages. Corrosion tests and postoperative examinations continue to provide information on construction materials. 12 figures, 3 tables.
