2Methyl-tetrahydrofuran (2Me-THF)/LiAsF/sub 6/ and several diethyl ether (DEE)/LiAsF/sub 6/-based electrolytes have been characterized for their usefulness in rechargeable Li/TiS/sub 2/ cells. This characterization has involved extended room temperature cell cycling at various depths of discharge, evaluation of rate/capacity behavior of cells at 25C and -10C, and storage of cells at 50C for up to one month with subsequent cycling. The thermal stability of the electrolytes at 71C was evaluated by storage experiments in sealed-tubes, followed by product analysis. The performance of 2Me-THF/LiAsF/sub 6/ cells far surpassed the others. The present data further substantiate previous reports from this laboratory of the superior behavior of 2Me-THF/LiAsF/sub 6/ solutions in rechargeable Li cells. The DEE/LiAsF/sub 6/ based electrolytes are too unstable thermally to be practically useful.
