Effect of Cu Powder as an Additive Material on the Properties of Zr-Based Pasted Alloy Electrodes for Ni/MH Batteries

Localization of Electrochemical Reactions in Electrocatalytic Processes on Nanocomposite Electrodes

“…It has been found that the discharge capacity of electrodes with 2.5% and 9% copper ( Figure 11, curves 1,2) is higher than that of electrodes with 5% copper (Figure 11, curve 3). These experiments and literature data [19] showed that the use of materials with high hydrogen evolution overpotential and hence the coefficient a in the Tafel equation makes it possible to improve the characteristics of hydride electrode. Thus, the principle of reaction localization is applicable to hydride electrodes too.…”

“…To prevent this reaction, the authors propose microcapsulation [19,20] . Another way of reducing corrosion is the use of polymeric electrolyte or good separators.…”
