High-performance batteries for off-peak energy storage and electric-vehicle propulsion. Progress report for the period July--September 1976. [Li--Al/Kcl--LiCl/Fes or FeS/sub 2/; tests of Li/TiS/sub 2/, Na/FeS/sub 2/, and CaMg/sub 2//FeS cells]
Research and management efforts on lithium--aluminum/metal sulfide batteries during the period July--September 1976 are described. These cells, which operate at 400--450/sup 0/C, are vertically oriented, prismatic cells with a central positive electrode of FeS or FeS/sub 2/, two facing negative electrodes of lithium--aluminum alloy, and an electrolyte of molten LiCl--KCl. A market study and an economic analysis are being performed; cells, cell components, and battery testing equipment are being developed and fabricated by industrial firms under contract; and work is in progress on designs for a 30 kWh electric-vehicle battery and a module for a stationary energy storage battery. Cells fabricated by Eagle-Picher Industries, Inc. were tested as single cells and as two- and three-cell batteries. Design modifications based on evaluations of these tests are in progress. New electrode and cell designs are also being developed and tested at ANL. The concepts receiving major attention include the design of multiple-electrode cells, the fabrication of electrodes in the uncharged state, the use of carbon-bonded current-collector structures in the positive electrode, the fabrication of electrodes by hot-pressing active materials and electrolyte, and the use of additives to the negative electrode. Materials development efforts included optimization of designs of electrical feedthroughs; development of improved electrode separators, e.g., BN and Y/sub 2/O/sub 3/ felts; corrosion tests of construction materials; and postoperative examination of cells. A new type of liquid-lithium electrode, in which lithium from a pool is wicked to the positive electrode, was developed. Investigations of alternative cell systems included tests of small-scale Li/TiS/sub 2/ and NaFeS/sub 2/ cells; a larger-scale CaMg/sub 2//FeS cell is also being operated. 22 figures, 5 tables.
