▎ 摘　　要

NOVELTY - The material has lead sulfate loaded to graphene, where mass ratio of the lead sulfate to the graphene is 0.1-10:1, or 0.5-8:1, or 0.8-6:1 or 0.9-4:1. USE - Lead sulfate-graphene composite electrode material for a lead acid battery cathode diachylon (claimed). Can also be used for an electric vehicle. ADVANTAGE - The composite electrode material has reversible oxidation reduction performance and capacitance performance, provides more lead sulfate growth points for the lead acid cathode, reduces sulfation of lead acid battery cathode in the high-rate pulse charge/discharge process and hydrogen potential of the graphene, and prolongs service life of the lead acid super storage battery. The pulse charge/discharge cycle index of the material is more than 6000 for first time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for lead acid battery cathode diachylon comprising lead sulfate-graphene composite electrode material DESCRIPTION OF DRAWING(S) - The drawing shows a microscopic view of lead sulfate-graphene composite electrode material.
