Lithium ion rechargeable intercallation cell

Claim 2

A lithium ion rechargeable intercallation cell comprising a lithiated graphite anode, a lithiated oxide cathode, and a solution of a lithium salt in a solvent that cycles lithium with both the lithiated graphite anode and the lithiated oxide cathode as the electrolyte.

Claim 3

A cell according to claim 1 wherein the lithiated graphite anode is Li x C 6 , wherein the lithiated oxide cathode is selected from the group consisting of Li x CoO 2 , Li x NiO 2 , Li x MnO 2 , Li x CrO 2 , Li x FeO 2 , Li x V 2 O 5 , and Li x V 6 O 13 , wherein the lithium salt is selected from the group consisting of LiAsF 6 , LiCF 3 SO 3 , LiClO 4 , and LiBF 4 , and wherein the solvent is selected from the group consisting of dimethyl carbonate, a mixture of dimethyl carbonate with propylene carbonate, a mixture of dimethyl carbonate with methyl acetate, a mixture of dimethyl carbonate with methyl formate, a mixture of dimethyl carbonate with acetonitrile, a mixture of dimethyl carbonate with diethyl carbonate, a mixture of dimethyl carbonate with tetrahydrofuran, a mixture of dimethylcarbonate with ethyl carbonate, and a mixture of dimethyl carbonate with 2-methyl tetrahydrofuran.

Claim 4

A cell according to claim 2 wherein the lithiated graphite anode is Li x C 6 , wherein the lithiated oxide cathode is Li x CoO 2 , and wherein the electrolyte is about 1 molar LiAsF 6 in dimethyl carbonate.
