ABSTRACT:
The subject invention discloses a novel electrolyte for a solid battery system. Specifically, an electrolyte solvent of chlorinated diethyl carbonates demonstrate good electrochemical stability in conjunction with specific anode and cathode materials. When used with a propylene carbonate co-solvent, it reduces or eliminates the decomposition of propylene carbonate during the first cycle. It is appropriate with a variety of electrolyte salts, and especially with LiBF.sub.4. Chloro-substituted diethyl carbonates also show good high and low temperature performance in electrochemical cells.
