ABSTRACT:
Non-aqueous solid electrochemical cells with improved performance can be fabricated by employing intercalation based carbon anodes comprising graphite, coke, or mixtures thereof, and an electrolyte having an electrolyte solvent formed of propylene carbonate and 4,5-dichloroethylene carbonate. The cells are particularly suited for low temperature applications.
