NOVELTY - An energy storage lead-acid storage battery comprises 100 pts. wt. lead oxide powder, 9-12 pts. wt. diluted sulfuric acid, 0.6-1.5 pts. wt. barium sulfate, 0.1-0.3 pts. wt. lignin, 0.05-0.2 pts. wt. graphene, 0.05-0.2 pts. wt. activated carbon, 0.08-0.20 pts. wt. short fiber and 8-11 pts. wt. pure water. USE - Energy storage lead-acid storage battery. ADVANTAGE - The energy storage lead-acid storage battery has better electrical conductivity and better capacitance characteristics and improves the life cycle. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a energy storage lead-acid storage battery, which involves placing lead oxide powder into the paste machine and adding separately barium sulfate, lignin, graphene, activated carbon and short fibers, drying for 3 minutes, adding pure water for 5 minutes, adding uniformly diluted sulfuric acid and adding continuously the acid under stirring, maintaining 70 degrees C for 3 minutes, turning on the cooling system and the dust removal fan of the paste machine, adding a small amount of pure water to adjust and stirring for 3 minutes until the apparent density of the lead paste meets the requirements to obtain the finished product.
