ABSTRACT:
An electrochemical cell containing a decomposing electrolyte solvent, further contains small amounts of an additive material such as lithium sulfide which causes partial self discharge of the cathode of the cell with non-reactive products. The self discharge partially deactivates substantially all of the active cathode surface as a reaction site thereby reducing the decomposition of the electrolyte solvent.
