Effect of Sulfur Impurities on Li / TiS2 Cells

Conditions leading to the generation of sulfur and hydrogen sulfide from can occur with uncontrolled handling of the active material during the fabrication of cells. These impurities affect the storage behavior of the ambient temperatures rechargeable organic electrolyte cells. An increase in the lithium anode polarization and self‐discharge of the cells is witnessed in the presence of these impurities. A mechanism of film formation and redox shuttle is discussed to account for the observed results.
