发明名称 Method for manufacturing storage battery electrode, storage battery electrode, storage battery, and electronic device
摘要 To provide a method for forming a storage battery electrode including an active material layer with high density in which the proportion of conductive additive is low and the proportion of the active material is high. To provide a storage battery having a higher capacity per unit volume of an electrode with the use of a storage battery electrode formed by the formation method. A method for forming a storage battery electrode includes the steps of forming a mixture including an active material, graphene oxide, and a binder; providing a mixture over a current collector; and immersing the mixture provided over the current collector in a polar solvent containing a reducer, so that the graphene oxide is reduced.

主权项 1. A method for manufacturing a storage battery, comprising the steps of: forming a mixture comprising an active material, graphene oxide, a binder, and a solvent; providing the mixture over a surface to form an active material layer; evaporating the solvent in the active material layer; reducing the graphene oxide in the active material layer to form a graphene; and consolidating the active material layer by a compression method, wherein the step of reducing the graphene oxide is performed in a polar solvent comprising a reducer.
