2010 Prius traction batteries are NiMH whereas most EV batteries are Li Ion I believe. Which might make a difference or might not, I don't know

- NewJazz 2y agoReminder that Chevron bought some key NiMH patents and used their ownership of those patents to prevent building batteries for cars. https://en.m.wikipedia.org/wiki/Patent_encumbrance_of_large_automotive_NiMH_batteries https://en.m.wikipedia.org/wiki/Patent_encumbrance_of_large_... If those patents hadn't been, or had they been shorter lived, or if antitrust law was more robust, we might have seen a lot more investment in optimizations on and variations of the NiMH chemistry. What a fascinating world I'll never live in.
- Tade0 2y agoI guess part of the reason is that the "M" in "NiMH" stands for Lanthanum - a rare earth element which happens to be used in catalysts facilitating oil refinement. Of course catalysts are consumed slowly, but you still don't want any disturbances in the supply of a key element.
