![]() Eagle-Picher has continued to use two layers of BN felt as electrode separators in its cells, whereas Gould has concentrated its efforts on MgO powder separators, which are believed to offer a near-term cost advantage but are in a somewhat less advanced stage of development. ![]() Development work by the two contractors consisted of cell design improvements to increase lifetime and specific power and the fabrication of cells for testing in contractor laboratories and at ANL. ![]() ![]() Particular emphasis was placed on investigations of alternatives to the present Li-Al and FeS electrodes that would be expected to lead to higher specific energy and power, i.e., investigations concerned with Li-Si, Li-Al-Si, Li-Al-Fe, FeS/sub more ยป 2/. The work at ANL has been concerned principally with the electrochemical and materials aspects of lithium-alloy negative electrodes and iron sulfide positive electrodes, materials research, cell design studies, and the testing and post-test examinations of cells fabricated by two industrial contractors-Eagle-Picher Industries, Inc. This report describes the work done on development of lithium/iron sulfide batteries at Argonne National Laboratory during FY 1982.
