摘　　要：铅酸蓄电池凭借其优良的性能价格比,在蓄电池领域中占有非常重要的地位。使用Sb2O3作为铅酸蓄电池正极添加剂,以自制的小型电池通过恒流放电,考察了Sb2O3对铅酸电池性能的影响,分析了Sb2O3在铅酸电池中的作用机理。结果表明,加入质量分数为2%～3%的Sb2O3提高了电池的放电容量和活性物质的利用率,改变了板栅腐蚀产物的结构,有利于活性物质结构的完整。Lead-acid batteries play an important role in secondary batteries due to its high ratio of performance to cost. The effect of Sb2O3 used as positive additive on lead paste was studies through constant current discharge with self-made batteries, and the mechanism of Sb2O3 in lead-acid was analyzed. The results show that the capacity and the utilization rate of active material can be increased, the structure of the corrosion products can be changed in the grid and the complete structure of active material can be helped by adding 2%-3% （ quality fraction ） Sb2O3.
