▎ 摘  要

NOVELTY - Manufacturing positive electrode involves mixing multiple particles of positive electrode active material, graphene oxide and water. The polymer aqueous solution is added to mixture of multiple particles of positive electrode active material, graphene oxide, and water to form slurry. The slurry is applied to current collector. The slurry is dried to form positive electrode active material layer. The graphene oxide is reduced in positive electrode active material layer. USE - Method for manufacturing positive electrode for secondary battery. ADVANTAGE - The method enables to manufacture positive electrode that has high potential, durability and energy density, provides electrons supply path, reduces contact resistance, and improves reliability.
