Abstract

The invention discloses a production method of a lead storage battery, which comprises the following steps: (1) preparing a positive plate and a negative plate; (2) respectively immersing the positive plate and the negative plate in a sulfuric acid solution to react; The plates are dried to obtain the pickled positive plate and the negative plate; (4) the pickled positive plate and the negative plate are assembled into a battery without additional addition of electrolyte. In the invention, required sulfate ions are obtained by impregnating sulfuric acid solution on the produced green pole plate, and battery assembly is completed by using the impregnated pole plate. Batteries can be exempted from the "Special Provisions" of the "International Maritime (Air, Rail, Road) Dangerous Goods Regulations" and shipped as non-dangerous goods. When the battery is used, it can be used only after adding pure water and fully charged, and the capacity of the battery itself and other related performances have no major impact.

Description

technical field [0001] The invention relates to the technical field of lead storage battery production, in particular to a production method of lead storage battery and the storage battery. Background technique [0002] G.Plante invented the lead-acid battery in 1859, and has experienced nearly 160 years of development. Lead-acid batteries have made great progress in terms of theoretical research, product types and varieties, and product electrical properties. , whether in transportation, communications, electric power, military or in various economic fields of navigation and aviation, lead-acid batteries have played an indispensable and important role. [0003] In the prior art, a lead-acid battery includes a battery tank, an electrode group and an electrolyte disposed in the battery tank. The electrode group includes a positive plate, a negative plate and a separator. Inside, then add the electrolyte, and then internalize the battery to activate the battery. [0004] For...
