So I've read from many sources. There is lots of evidence to support this. As I understand it, the "metal" in nickel metal hydride cells is -- guess what -- iron. So if NiFe can have such an extended cycle life, why can't NiMH? In fact, NiMH can have outstanding cycle life. Consider those remarkable Toyota RAV4-EVs from 15+ years ago, with Panasonic NiMH batteries lasting well over 100,000 miles. Don't you wonder if maybe NiMH could have cycle life approaching that of NiFe, if they were designed for it? And haven't the patents encumbering the manufacture of large, BEV-sized NiMH modules expired now?
