摘　　要：本文选用3,5-二氨基苯甲酸和氧化铋作为电解液添加剂,实验发现在电解液中添加600～5.28×10-3～6.16×10-3 mol/L浓度的3,5-二氨基苯甲酸能够减少Pb（II）膜的生长,从而减缓电池出现早期容量损失;同时在电解液中添加0.16×10-3～0.22×10-3 mol/L浓度的铋离子能够提高合金的析氢过电位,减少电池在循环过程中的失水量,延长了电池的使用寿命。In this paper, 3,5-diaminobenzoic acid and bismuth oxide as additives of electrolyte are studied. The results show that 5.28×10-3～6.16×10-3 mol/L 3,5-diaminabenzoic acid added into the electrolyte can inhibit the growth of Pb（II） corroded fi lm. This is an effective approach to solve the PCL problem. We also fi nd that 0.16×10-3～0.22×10-3 mol/L bismuth oxide added into the electrolyte can increase hydrogen over-potential and reduce the water loss in the process of cycle life, which lengthens the life of batteries.
