Research, development, and management activities of the program at Argonne National Laboratory (ANL) on lithium--aluminum/metal sulfide batteries during January to March 1977 are described. The present cells, which operate at 400 to 450/sup 0/C, are of a vertically oriented, prismatic design 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 major objective of this program is to transfer the technology to industry. Testing and evaluation of industrially fabricated cells is continuing. During this period, Li--Al/FeS and Li--Al/FeS/sub 2/ cells were tested. These tests provide information on the effects of design modification and alternative materials for cells. Improved electrode and cell designs are being developed and tested. The materials development efforts include the development of a new, lightweight electrical feedthrough; studies of various current-collector designs; investigation of Y/sub 2/O/sub 3/ powder as separator material; wettability tests of materials for cell components; and postoperative examinations of cells. The cell chemistry studies were concerned with discharge mechanisms of FeS electrodes, with the mechanism of loss of sulfur and iron from FeS/sub 2/ electrodes, and with other transition-metal sulfides as positive electrode materials. The advanced battery effort investigated the use of calcium alloys for the negative electrode and the use of an iron current collector in the positive electrode. 19 figures, 16 tables.
