Abstract

The invention discloses positive grid alloy of a lead-acid storage battery. The positive grid alloy of the lead-acid storage battery is characterized by being high in tin content and low in calcium content, and comprises, by weight percentage, 0.04 %-0.07 % of calcium, 1.3 %-1.8 % of tin, 0.01 %-0.05 % of aluminum, 0.02 %-0.07 % of silver, and lead as the rest. The positive grid alloy of the lead-acid storage battery has the advantages of being strong in corrosion resistance, high in strength, and strong in the ability to recover from deep discharging. The aluminum not only reduces the loss of the calcium, but also plays a role in refining grains, the silver reduces corrosion and improves (refines) the structure of the grains, rare elements are capable of reducing the loss of water, and therefore the service life of the storage battery is largely prolonged.

Description

technical field [0001] The invention relates to a positive grid alloy of a lead-acid storage battery. Background technique [0002] The current lead-acid battery is easy to lose water after repeated use, resulting in a decrease in the recovery ability of the battery discharge and shortening the service life of the battery. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to improve a kind of positive grid alloy, which is very corrosion-resistant, very good in strength, and strong in deep discharge recovery ability, wherein Al not only reduces Ca loss, but also has the effect of refining crystal grains, and Ag reduces corrosion and improves (Refined) grain structure, rare elements reduce water loss. [0004] In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: [0005] Lea...
