New Electrolytes for Secondary Li/TiS2 Cells

Abstract:

The key to widespread application of rechargeable lithium cells is an electrolyte
which does not undergo reactions leading to cell venting under all likely conditions
of cell abuse (electrical, mechanical, or thermal). This project will synthesize
a number of new lithium salts and characterize their performance as electrolytes
in Li/TiS2 cells. Characterization will include conductivity, stability in contact
with lithium and TiS2, and effects on the cycling behavior of the cell. Promising
electrolytes will be further evaluated in cycled Li/TiS2 cells at temperatures above
the melting point of Li.
A safe, well-behaved lithium salt with high conductivity will make possible the general
use of Li/TiS2 and other rechargeable Li cells.
