Abstract
The invention relates to a high-performance zinc-nickel storage battery. Mg[Al(OH)4]2 or Ca[Al(OH)4]2 as a paint is coated on a membrane; the thickness of the paint on the membrane is 0.2-0.25 mm; an anode and a cathode are respectively sealed and coated by the membrane; the Mg[Al(OH)4]2 or the Ca[Al(OH)4]2 is generated by reacting metallic aluminum with a supersalinity solution and then reactingwith Mg(OH)2 or Ca(OH)2. In the invention, the membrane is coated with the paint so as to be prevented from being pieced by a zinc dendrite, thereby effectively preventing the inner short circuit andgreatly prolonging the service life of the battery. Compared with a lead-acid battery, the weight of the zinc-nickel storage battery is only 1/3 that of the lead-acid battery and the service life of the zinc-nickel storage battery is prolonged by 3-4 times as comparison with the lead-acid battery; and compared with a lithium ion battery, the service life of the zinc-nickel storage battery is equivalent to the repeated charging for 1,000-2,000 times and the cost of the zinc-nickel storage battery is 1/3 of the cost of the lithium ion battery.
