Embodiment 1
[0052]In this example, the positive and negative lead paste of the lead-acid battery, the mass parts of each component of the lead paste are 100 parts of lead powder, 1 part of lead-tin 1wt.% alloy powder, 0.8 part of barium sulfate, 10 parts of dilute sulfuric acid, and 8.5 parts of ionized water. Among them, the lead-tin 1wt.% alloy means that the mass proportion of tin contained in the lead-tin alloy is 1%, and the following are similar.
[0053]The lead powder is ball milled lead powder with an oxidation degree of 75%; optionally, the lead powder may also be lead oxide with a degree of oxidation of 100%.
[0054]The method for preparing the positive and negative lead pastes of the present embodiment includes the following steps: weigh each component according to the above-mentioned lead paste formula, and add lead powder, lead-tin 1wt.% alloy powder, and barium sulfate into the paste machine Stir for 5 minutes, mix well, quickly add deionized water, stir for 5 minutes, then slowly add...
Embodiment 2
[0056]The difference from Example 1 is that the positive and negative lead pastes of the lead-acid battery of this example are composed of 100 parts of lead powder, 2 parts of lead-samarium 0.3wt.% alloy powder, and barium sulfate. 0.8 parts, 10 parts dilute sulfuric acid, 8.5 parts deionized water.
Embodiment 3
[0058]The difference from Example 1 is that the lead-acid battery positive and negative lead pastes of this example contain 100 parts by mass of lead powder and 0.5wt.% lead-lanthanum-tin 1wt.% alloy powder. 3 parts, 0.8 parts of barium sulfate, 10 parts of dilute sulfuric acid, 8.5 parts of deionized water.
