Development of Porous Sintered-Ceramic Separators for Application in a Li--Al/LiCl--KCl/FeS Battery
Abstract
The procedure for fabrication of porous sintered-ceramic separators and the technical feasibility of using such separators in Li-Al/molten LiCl-KCl/FeS battery cells have been investigated. Processing techniques have been developed to fabricate ~1.5-2.5 mm thick, ~35-60% porous, flat, sintered Y{sub 2}O{ sub 3} and MgO separator plates with sufficient strength to allow handling prior to and during cell assembly. These separators performed successfully in laboratory-scale cells for up to ~2000 h and 283 cycles, indicating that the concept of a sintered separator is viable for Li-Al/FeS batteries. The particularly attractive features of these separators are potentially low cost, pre-fabricated form that allows easy cell assembly, and small pore size (average diameter 0.5-1.0 ~m) which provides good particle retention. The test results from the sintered-separator cells indicate that Y{sub 2}O{ sub 3} is probably unsuitable for long-term performance in Li-Al/FeS cells because of its reaction with the positive active material. This is in agreement with the recently reported data on cells with Y{sub 2}O{ sub 3} felt and powder separators. Sintered MgO separators, however, showed good chemical and mechanical stability in the cell environment. (auth)
