The invention discloses a method for preparing a graphene-supported metal oxide electrode material. GO/metal salt suspension; with cleaned nickel foam, copper foam, etc., aluminum foil or copper foil as substrate and current collector, the above-mentioned suspension is coated on the metal surface by ultrasonic spraying method to obtain graphene-supported metal oxide Object electrode material. The metal oxide formed in situ in the present invention is evenly distributed on the graphene surface, and the electrode material exhibits good pseudocapacitive performance. The invention avoids the use of binders, and does not require annealing treatment, the electrode preparation process is simple, and batch preparation is easy to achieve. |
