Patent ID: 7195844

Claim:
A lithium secondary battery comprising (1) positive and negative electrodes each comprising at least an active material capable of occluding and releasing lithium ions, a binder, and a current collector, (2) a conductive adhesive layer for at least one of said positive and negative electrodes, and (3) an electrolytic solution, wherein the active material in at least one of said positive and negative electrodes has been made conductive by coating its surface with a conductive agent and the binder, and which coated active material is then formed into a sheet, which sheet is then affixed to the surface of the conductive adhesive layer for said electrode by a dry process, wherein the sheet is bonded to said conductive adhesive layer, resulting in said conductive adhesive layer being located between the sheet and the current collector, and wherein the negative electrode active material is synthetic graphite having a lattice spacing of 0.335 to 0.380 nm between lattice faces (002).
