Highly conductive and stable nonaqueous electrolyte for lithium electrochemical cells

   
   

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 comprises 1,2-dimethoxyethane, propylene carbonate, dimethyl carbonate and diisopropyl ether.

La actual invención se dirige por lo menos parcialmente a substituir la PC y/o el DME por un carbonato linear, carbonato preferiblemente dimethyl, y un mono-e'ter linear, preferido el ser éter diisopropyl, en los electrólitos útiles para activar las células metal-que contienen del álcali. Este electrólito ha mejorado conductividad y provee de las células electroquímicas funcionamiento realzado de la descarga. Un electrólito preferido abarca 1,2-dimethoxyethane, el carbonato del propylene, el carbonato dimethyl y el éter diisopropyl.
