▎ 摘　　要

NOVELTY - Manufacturing a positive electrode (165), comprises: forming a mixture including a lithium-containing composite oxide having an olivine structure and a graphene oxide, on a positive electrode current collector (175); applying a pressure to the mixture vertically or substantially vertically to a surface of the positive electrode current collector; and reducing the graphene oxide. USE - The method is useful for manufacturing a positive electrode which is used for a lithium secondary battery (claimed) for supplying electric power to electric appliances. ADVANTAGE - The method: provides positive electrode in which b-axes of lithium-containing composite oxide single crystals are oriented vertically to a surface of a positive electrode current collector; utilizes graphene oxide or multilayer graphene oxide (reduced) that has high conductivity and low frictional properties; and provides positive electrode which is utilized in battery that exhibits small memory effect, a high energy density, and a high charge/discharge capacity, high output voltage, small size and more lightweight than a conventional secondary battery even when they have the same capacity, and little degradation and long-time use. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a positive electrode for a lithium secondary battery, comprising a positive electrode current collector, and positive electrode active material layer over the positive electrode current collector, where the positive electrode active material layer includes the lithium-containing composite oxide; and (2) a lithium secondary battery, comprising a negative electrode (163), an electrolyte solution (169) and the positive electrode. DESCRIPTION OF DRAWING(S) - The figure shows a cross sectional view illustrating the lithium secondary battery.
