▎ 摘　　要

NOVELTY - Preparation of zinc ion electrode comprises: (i) dispersing graphene and binder in dispersing agent to obtain slurry, (ii) uniformly coating the slurry on one surface of the zinc foil to obtain intermediate, (iii) pressing uncoated surface of the intermediate on the foam metal sheet under a predetermined pressure to obtain the prefinished product, and (iv) drying the pre-finished product to obtain the electrode. USE - Preparation method of zinc ion electrode used in hybrid super capacitor (claimed) used as energy storage device for electronic device. ADVANTAGE - The method effectively inhibits the dendritic crystal growth of zinc ion electrode and effectively inhibit the secondary reaction of the electrode. The method provides the electrode with stable structure and high safety. The service life of the hybrid super capacitor is long, and the capacitor performance is good. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a zinc ion electrode; and (2) a hybrid super capacitor.
