Abstract

The invention relates to a preparation process of a battery pole plate of a lead-acid battery with high cycle performance, the battery pole plate of the lead-acid battery comprises a positive pole plate and a negative pole plate, the preparation process of the positive pole plate comprises the following steps: step 1, preparing raw materials of the positive pole plate, including 0.07-0.10 part of calcium, 0.004-0.025 part of lanthanum, 1.4-1.5 parts of tin, 0.015-0.025 part of aluminum, 0.002-0.0025 part of silver and the balance of lead powder; 2, preparing a lanthanum-tin master alloy, wherein the lanthanum-tin master alloy comprises 20% by weight of lanthanum and 80% by weight of tin; step 3, preparing a calcium-aluminum master alloy; step 4, preparing a positive plate, adding lead powder into a smelting furnace, heating to melt, then sequentially adding the calcium-aluminum master alloy, the lanthanum-tin master alloy and the residual tin, and uniformly stirring to obtain a positive plate alloy; and preparing the positive plate alloy into the positive plate. The positive plate battery plate prepared by the invention has good corrosion resistance and high mechanical strength.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a process for preparing battery plates of lead-acid batteries with high cycle performance. Background technique [0002] There are many reasons for the failure of the lead-acid battery service life, and the common reasons are: (1) corrosion of the positive plate of the lead-acid battery; (2) sulfation of the negative plate. specific: [0003] After the positive plate is corroded, lead oxides and salts are formed, which makes the positive plate lose its supporting active material and conductivity, and affects the service life of the battery. [0004] The negative electrode active material of the negative plate appears sulfation phenomenon, that is, the negative electrode generates irreversible large-particle crystal lead sulfate, and the conductivity of the negative plate of the battery becomes poor. [0005] Both of these conditions will result in impacts on battery...
