【摘要】 以不同电流密度放电、氢析出过电势、循环伏安、通电电解时被阳极氧化时的稳定性等方法 ,比较了膨胀剂木素磺酸钠 ,扩散剂N (或称NNO ,是一种染料助剂 ) ,结果表明 :染料助剂NNO完全可以当作铅酸蓄电池负极的膨胀剂使用。更多还原

【Abstract】 The effect of some expanders,such as sodium lignosulfonate,diffusion agent N(also named as NNO),was investigated using cyclic voltammetry.The diffusion agent N was compared with sodium ligno sulfonate in regard to overpotential of hydrogen evolution,stability of anodic process and discharge performance under different current values.The results show that NNO,a kind of dyeing assistant,can be used as expanders of negative electrode in lead acid battery.更多还原
