Charge of zincate
Compared with cadmium hydroxide, the tendency of the soluble zinc hydroxide ion (zincate) to dissolve into solution and not fully migrate back to the cathode during recharging has, in the past, presented challenges for the commercial viability of the NiZn battery. Another common issue with zinc rechargeable batteries is electrode shape change and dendrites (or "whiskers"), which may reduce the cell discharging performance or, eventually, short out the cell, resulting in a low cycl… WebMar 29, 2004 · In comparison, the semicircle for zinc anode in the SDBS-containing electrolyte shows a much larger diameter semicircle than that obtained in blank solution, …
