Abstract:

This report details the work performed on Phase I of an overall two- phase program. The aim of Phase I is to select a room-temperature lithium Li rechargeable couple that offers high energy density 60-90 Wh1b, good rate capability C6-C1, and low temperature operability. Among the four cathode systems investigated - V205, Tis2, v2s5 and LixCo02 - the LiV2O5 couple emerged as the best performer capable of meeting the performance goals described above. The other three cathode systems were dropped from further development during the course of the program because of their general instability with ester-based electrolytes, especially the methyl formate MF-based electrolyte. The MF-based electrolyte was selected because of its superior conductivity which is essential for rate capability and low temperature operability.
