HIGH-PERFORMANCE BATTERIES FOR OFF-PEAK ENERGY STORAGE AND ELECTRIC-VEHICLE PROPULSION. PROGRESS REPORT, JANUARY--MARCH 1976

The research and management efforts of Argonne National Laboratory's program on lithium/metal sulfide batteries during the period January--March 1976 are described. These batteries are being developed for energy storage on utility networks and for electric-vehicle propulsion. The present cells are vertically oriented, prismatic cells with a central positive electrode of FeS or FeS sub 2 and two facing negative electrodes of lithium--aluminum alloy, and an electrolyte of molten LiCl--KCl. The cell operating temperature is 400 to 450 exp 0 C. The type of cell receiving major attention is one in which the electrodes are assembled in the uncharged state. The active material in the positive electrode is a mixture of Li sub 2 S and iron; the electrode is formed by hot-pressing this material with electrolyte, by loading it into a porous structure of metal, or by incorporating it into a carbon-bonded structure. The negative electrode is a porous aluminum structure, with which the lithium reacts on first charge to form a lithium--aluminum alloy. Several methods of adding excess lithium capacity to the cell are being investigated. Efforts are being made to develop feedthroughs and electrode separators that meet performance and cost goals. Work is also being carried out on an improved design of a battery for energy storage on utility networks and on design and fabrication of other battery components. Li sub 2 S is being characterized in terms of purity and physical characteritics to determine its suitability for use in fabricating uncharged cells. Work is continuing on the development of alternative secondary cell systems with calcium- or magnesium- based negative electrodes and molten-salt electrolytes. 20 figures, 13 tables.
