Abstract

The invention discloses a negative plate alloy configuration process and relates to the technical field of storage batteries. The negative plate alloy of the present invention comprises the following components: Ca 0.1-0.5%, Sb 1-3%, Sn 0.05-0.1%, As 0.05-0.1%, Al 0.02-0.05%, S 0.01-0.025%, Cd 0.1-0.3 %, Ag 0.05-0.2%, Cu 0.05-0.2%, and the balance is lead; the preparation process includes adding high-calcium master alloy and electrolytic lead-lead pellets to the reactor in sequence, controlling the temperature to 500-800°C, shaking or stirring for 1h , continue to heat up to 800-1100°C, shake or stir for 1 hour, then continue to heat up to 1050-1150°C, shake or stir for 3 hours to prepare the alloy liquid; cool the prepared alloy liquid, and pour it into the ingot mold after cooling After cooling to room temperature, put the prepared alloy ingot into water, soak and cool for 1 hour, take it out and dry it to obtain the negative electrode grid alloy. The alloy material of the negative plate of the invention has excellent mechanical properties and excellent corrosion resistance, high H precipitation overpotential; the manufacturing process of the alloy is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to a negative plate alloy configuration process. Background technique [0002] With the development of lead-acid battery technology, a lot of research has been done on the key component of the battery: the alloy material of the grid. At present, Pb-Ca-Sn-Al alloy is widely used at home and abroad to make grids and assemble sealed lead-acid batteries. This type of alloy has the following defects: the mechanical strength of the alloy is low, and it cannot meet the requirements of large-scale storage batteries. Due to the formation of lead sulfate on the surface of the negative grid made of this alloy, the grid is deformed and expanded, which can easily cause a short circuit inside the battery, resulting in battery failure. Short life. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The purpos...
