Talk:Nickel–zinc battery

How is "common oxidation is +2" an advantage?
At the very end of the "Advantages" section, it says "Common oxidation is +2, so charge and discharge move two electrons instead of one as in NiMH batteries." Can this part be expanded on, please? It needs some explanation of how that's an advantage over NiMH batteries. Heddy10 (talk) 02:30, 1 May 2022 (UTC)
