HIGH-PERFORMANCE BATTERIES FOR OFF-PEAK ENERGY STORAGE AND ELECTRIC-VEHICLE PROPULSION. PROGRESS REPORT, JULY--DECEMBER 1975

This report describes the research and management efforts of Argonne National Laboratory's program on high-performance lithium/metal sulfide batteries during the period July--December 1975. The batteries are being developed for two applications: off-peak energy storage in electric utility networks and electric-vehicle propulsion. The battery designs for the two applications differ, particularly in cell configuration and electrode design, because of the differing performance requirements. The present cells are vertically oriented, prismatic cells with two negative electrodes of a solid lithium--aluminum alloy and a central positive electrode of iron sulfide (FeS sub 2 or FeS). The electrolyte is molten LiCl--KCl eutectic, which requires a cell temperature of about 400--450 exp 0 C. Effort was continued on the development of engineering-scale cells with hot-pressed electrodes assembled in the uncharged state (positive electrode of Li sub 2 S--Fe, negative electrode of Al). Studies of electrodes were directed principally toward developing positive electrodes of FeS sub 2 and FeS in carbon-bonded structures and toward improving the performance and lowering the cost of negative Li--Al electrodes. Materials studies included work on improved separators and feedthroughs, corrosion tests of materials in the cell environment, and postoperative examinations of cells. Work in the area of cell chemistry included the continuing studies of cell reactions and investigations of advanced cell systems. Battery design work was directed toward the design of a battery for an electric vehicle, development of battery components, and design and construction of battery testing facilities. Efforts were continued on contractual arrangements with industrial firms to develop and fabricate cells, electrodes, and cell components; the first contractor-produced cells were delivered to ANL.
