Patent ID: 8021791

Claim:
An electrochemical cell, comprising: an anode comprising a salt and an anode surface; a cathode insulated from the anode, said cathode having a cathode surface; a non-aqueous electrolyte in contact with the anode and consisting of an organic solvent that consists of trimethylene carbonate and dimethyl carbonate; said non-aqueous electrolyte produces a stable solid electrolyte interface on said anode surface during an initial discharge of said cell when a plurality of reduction products from upon said anode surface to prevent formation of an insulating film on said anode surface; said non-aqueous electrolyte produces said stable solid electrolyte interface on said cathode surface during said initial discharge when a plurality of oxidation products form upon said cathode surface; said stable solid electrolyte interface on said anode surface and said cathode surface permits a lithium ion intercalation allowing a plurality of lithium ions to diffuse through to said anode surface and said cathode surface resulting in an increased electron transfer and an enhanced cell performance; and said anode being selected from the group of anodes consisting of graphite and carbon.
