The lead alloy for the accumulator grid comprises the following ingredients, by weight, 0.19-0.22% of calcium, 0.60-0.80% of tin, 0.04-0.06% of aluminium, iron being less than or equal to 0.002%, bismuth being less than or equal to 0.004%, zinc being less than or equal to 0.001%, antimony being less than or equal to 0.001%, silver being less than or equal to 0.001%, copper being less than or equal to 0.0015%, arsenic being less than or equal to 0.001%, and the balance lead. According to the invention, problems such as low mechanical strength and high internal resistance of an accumulator plate can be solved.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to an alloy for manufacturing lead-acid storage battery grids. Background technique [0002] Lead-acid batteries are preferred for hybrid electric vehicles and electric vehicles because of their low price, stable cell voltage, high safety performance, and good manufacturing foundation. They have great advantages and a huge market. [0003] The core component of the battery is the pole plate, and the performance of the pole plate is directly determined by the grid and lead paste, and the quality of the grid depends on the performance of the grid lead alloy. The quality of the grid lead alloy affects the strength of the grid, and the content of each alloy element in the grid lead alloy has a great influence on the electrical and mechanical properties of the plate. The main problems of existing grid lead alloys are low mechanical strength and high internal resistance. Conte...
