▎ 摘　　要

NOVELTY - The electrode has a three-dimensional porous foam nickel substrate formed with graphene. The graphene is made of flower delta-manganese oxide. Load amount of the flower delta-manganese oxide is about 0.45 to 1.5mg/cm2. USE - Three-dimensional graphite alkenyl composite electrode for a large-scale production industry. ADVANTAGE - The electrode is inexpensive, has low polarization display effect and better circulation stability, and reduces processing time consumption and energy consumption, avoids conductive agent and binder and realizes three-dimensional graphite alkenyl composite electrode preparing process in a simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a three-dimensional graphite alkenyl composite electrode preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing characteristics of a three-dimensional graphite alkenyl composite electrode.'(Drawing includes non-English language text)'
