▎ 摘 要
NOVELTY - Positive electrode manufacturing involves forming a mixture including a lithium-containing composite oxide having an olivine structure and a graphene oxide, on a positive electrode current collector (120). A pressure is applied to the mixture vertically or substantially vertically to a surface of the positive electrode current collector. The graphene oxide is reduced. USE - Method for manufacturing positive electrode for a lithium secondary battery used in portable device, such as smartphones and portable game consoles or automotive power supply. ADVANTAGE - The method manufactures the positive electrode in a simple and cost-effective manner with increased capacity and an improvement in output performance, high energy density, and a high charge/discharge capacity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the positive electrode.
