Abstract:

The usefulness of tetrahydrofuran THF as a cosolvent with 2-methyltetrahydrofuran 2Me-THFLiAsF6 for improving the low temperature rate capability of rechargeable Li cells has been explored. LiTiS2 cells utilizing 2Me-THFLiAsF6 blended with 15-50 volume-percent THF have shown substantially improved rate characteristics at 0 and -10C. In addition, the Li electrode in such cells has exhibited practically useful cycling efficiencies. Author
