ABSTRACT:
The present invention is directed to at least partially replacing PC and/or DME with a linear carbonate, preferably dimethyl carbonate, and a linear mono-ether, the most preferred being diisopropyl ether, in electrolytes useful for activating alkali metal-containing cells. This electrolyte has improved conductivity and provides electrochemical cells with enhanced discharge performance. A most preferred electrolyte comprises1,2-dimethoxyethane, propylene carbonate, dimethyl carbonate and diisopropyl ether.
