Claim Text:
1. A lithium-ion cell comprising: (a) a positive electrode (cathode) comprising graphene as the only cathode active material having a surface area to capture and store lithium thereon and wherein said graphene cathode is meso-porous having a specific surface area greater than 100 m (b) a negative electrode (anode) comprising an anode active material for inserting and extracting lithium during a charge and discharge of said cell, wherein said anode active material is mixed with a conductive additive and/or a resin binder to form a porous electrode structure, or coated onto a current collector in a coating or thin film form, and wherein said anode active material is not pre-lithiated and is lithium-free when the cell is made, and wherein the anode active material is selected from the group consisting of: (c) a porous separator disposed between the anode and the cathode; (d) a lithium-containing electrolyte in ionic contact with the anode and the cathode; and (e) a lithium source disposed in at least one of the two electrodes when the cell is made.
