▎ 摘 要
NOVELTY - The method involves providing an ultrasonic dispersion system into graphene oxide colloidal solution according to the ratio of graphene oxide weighed. The high-voltage electrostatic spraying device is used for spraying graphene oxide on current collector. Graphene film light unit is reduced so as to give light to reduction of graphene membrane electrode. USE - Method for preparing light reducing graphene film electrode. ADVANTAGE - The light wave reduces graphene film electrode and provides good conductive structure and three dimension structure. The capacity of lithium ion battery isincreased and performance is increased.
