摘　　要：木质素是铅酸电池负极活性物质的有机添加剂之一。通过测量木质素在铅酸蓄电池中的含量变化,有助于预判铅酸蓄电池低温下的放电性能变化趋势。笔者采用紫外–可见光分光光度计,系统测试了铅酸蓄电池化成过程中和性能测试后负极板与电解液中木质素的变化量。Lignin is one of the most critical organic additives in the negative active materials of lead-acid batteries.By measuring the change of lignin content in lead-acid battery,it is helpful to predict the change trend of discharge performance of lead-acid battery at low temperature.The change of lignin in negative plate and electrolyte after neutralization performance test of lead-acid battery was systematically measured by UV-visible spectrophotometer.
