High-temperature (450 to 470/sup 0/C) LiAl/FeS cells are being developed at Argonne National Laboratory (ANL) in partnership with industrial contractors, e.g., Eagle-Picher Industries and Gould, Inc. These secondary cells (400 Ah), designated as Mark II cells, are designed for use in rechargeable modules primarily intended for electric vehicles. The cells consist of a multiple electrode stack of two or three positive electrodes with facing negative electrodes which are electrically insulated by layers of BN felt. It is anticipated that modules will probably undergo thermal (freeze-thaw) cycling during their lifetime; therefore, a major factor in the long term sucess of the lithium/iron sulfide battery is the ability of its room temperature without failure or deterioration of performance. A series of LiAl/FeS bicells (300 cm/sup 2/; 65 Ah limiting positive electrode) was initiated at ANL to characterize the effects of repeated freeze-thaw cycling. The cells were to serve a two-fold purpose; (1) to compare known methods of (BN felt) separator pretreatment and their ability to maintain separator wettability, as evidenced by unaffected cell capacity, sical stress of repeated electrode and electrolyte volumetric changes associated with cycling. Results are presented and discussed. (WHK)
