ELECTRODE FOR STORAGE BATTERY AND MANUFACTURING METHOD THEREOF, STORAGE BATTERY, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To increase the efficiency of a reaction in which graphene oxide is reduced in a mild condition and to enhance storage battery's cycle characteristic and rate characteristic in manufacturing an electrode for a storage battery, which includes graphene as a conductive assistant.SOLUTION: A method for manufacturing an electrode for a storage battery is provided, which comprises the steps of: preparing a first mixture having an active material, a graphene oxide and a solvent; preparing a second mixture by adding a reductant to the first mixture to reduce the graphene oxide; preparing a third mixture by mixing the second mixture with a binding agent; coating a current collector with the third mixture; and evaporating the solvent, thereby forming an active material layer.SELECTED DRAWING: Figure 1
