摘要
对腐植酸、木素磺酸钠、新型膨胀剂影响铅电极的电化学行为及极板放电性能进行了研究。循环伏安极化曲线表明不同有机膨胀剂对铅电极电化学行为影响规律相同;阴极极化曲线表明上述不同有机膨胀剂对析氢的影响差别可以忽略不计;首次放电性能试验与循环伏安结果一致。分析了腐植酸与木素相同与不同的作用机理。相同点在于影响铝电极电化学行为原理相同,不同点在于腐植酸主要通过吸附来防止负极收缩,而木素磺酸钠则主要通过造孔来防止负极收缩。
The influence of humic acid,sodium lignosulphonate and new expander on electrochemical characteristics of lead electrode was studied by the cyclic vlotammetry technique.The cathodic polarization curves and discharge perfor- mance were tested.The effect mechanisms of above expanders were anslyzed,and a new organic expander obtained from chemical combination was suggested.
