▎ 摘  要

NOVELTY - A lead accumulator graphene paper grid additive comprises imidazoline derivative and diethylenetriamine. The weight ratio of the imidazoline derivative to the diethylenetriamine is 1:1-1:5. The imidazoline derivative is imidazoline laurate or imidazoline oleate. The lead paste comprises 330-500 pts. wt. lead powder, 60-220 pts. wt. tin powder, 10-20 pts. wt. graphene powder and 20-40 pts. wt. additives. USE - Lead-acid battery graphene paperboard grid additive for use in lead-acid battery field (claimed). ADVANTAGE - The lead-acid battery has excellent electrochemical performance and mechanical performance, corrosion resistance, light weight, and excellent electrical performance, mechanical performance and service life, and has wide market application prospect. The graphene paper as the framework main body of the grid, and then coating the sintered lead layer on the surface of the graphene paper surface, realizes the lead- acid battery light weight and the grid has good conductive capability, and can obtain the light weight of the battery grid. The additive improves the bonding strength of the metal lead and graphite, improves the firmness of the lead layer and graphene paper, and the electrochemical and mechanical performances of grid is excellent. The battery has corrosion inhibiting ability, and prolonged service life of grid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene lead-acid battery grid.
