Abstract: The paper describes the method to process the positive and negative grids of lead-acid batteries with COz-rich vapor.Basic lead carbonate is generated on the surfaces of positive and negative grids which be made into the plates of power lead-acid batteries and then be assembled.The experimental data showed the method can increase the strength of the electrode plate, improve the charging pass rate ofbatteries in bulk and the cycle consistency of thebatteries, extend the service life and upgrade the overall performance of the lead-acid battery.
Key words: grid processed with CO,-rich vapor; basic lead carbonate; power lead-acid battery; the consistence of battery performance

因素有正极板栅腐蚀变形、活性物质软化脱落、负极板栅汇流排腐蚀、电解液干、不可逆硫酸盐化等。涂膏和固化是生产铅酸电池的两道关键工序,两者质量的好坏直接影响电池的一致性、熟极板的质量(),以及电池的初期性能和使用寿命。在涂膏和固化中提高极板活性物质与板棚之间的接触性能,减小活性物质与板栅之间的接触电阻,保障活性物质之间以及与板棚栅之间的融合一致性,是提高极板一致性和减少活性物质脱落的关键。
