摘　　要：将对硝基苯甲酸用作铅酸电池负极添加剂。利用线性扫描伏安法测量阴极极化曲线,得到添加剂对负极析氢过电位和析氢速率的影响;通过对电池失水、充电接受能力、低温性能和循环寿命的测试,结合SEM分析,研究添加剂对电池性能的影响。对硝基苯甲酸能降低电池负极析氢速率;在实验条件下,减少50%水损耗,并降低自放电,提高充电接受能力和低温性能。采用6 A电流,100%放电深度条件下,260次循环后,含0.01%添加剂的铅酸电池的容量保持率在87%以上。P-nitrobenzoic acid was used as additive in lead-acid battery negative electrode.Cathodic polarization curves were obtained by linear sweep voltammetry and the influence of addictive on hydrogen evolution overpotential and hydrogen evolution rate could be investigated.Researches on the battery fluid loss,charge acceptance,low-temperature performance,cycle life and SEM images were performed to study the effects of battery addictive.P-nitrobenzoic acid could reduce the hydrogen evolution rate at negative electrode,reduce water loss of 50%,reduce self-discharge,improve charge acceptance and low-temperature performance.At 6 A and 100%deep of discharge(DOD),after 260 cycles,the battery containing additives of 0.01%still had the capacity retention of more than 87%.
