氧化镍/氢氧化镍是一种性能优异的超级电容器的电极材料，借助阳极氧化工艺，可发挥其优异的超级电容特性，然而阳极氧化成膜过程涉及增重和酸溶解过程，因此，不能采用成膜前后称量的方法得出膜的质量。为了解决这一问题，提出了一种阴极电化学方法，该方法可以溶解氧化膜而不损害基体，进而通过差重法，精确得到氧化膜质量。

Nickel oxide or nickel hydroxide is one of supercapacitor electrode materials with excellent performance .Among different preparing methods ,anodized oxidtion is a promising technology in the field of spercapcitor ,becasuse it can provide nickel oxide or nickel hydroxide with higher electrochemical properties . However ,formation process of anodization film involves two steps of anodizaton weight gain and acid dissolution .Therefore ,the method by directly weighting the sample before and after anodic film can not be adopted .To solve this problem ,a noval test method is proposed ,namely ,a cathodic electrochemical method in 85wt% H3 PO4 is used to dissolve oxide film ,which can not harm the substrate .By this ,the mass of the anodic film can be successfully obtained .
