reason is the formation of insoluble nickel hydroxide. Due to the markedly increase in the surface pH, the current density increases. Figure 4 shows the effect of current density on the current efficiency... a higher polarization of the cathode, even increase the cell voltage [18]. Meanwhile, with the increase of current density, the formed insoluble nickel hydroxide depresses the reduction of nickel ion......
