In environmental costs, I'd much rather have FeNi chemistry fully explored. Nickel iron batteries can be abused by under and over charging, short circuiting heat, cold, vibration, and other effects and still last decades.
Jay Leno has an antique car that still has a working FeNi battery. I think it needs topped off with distilled water every so often. The electrolyte is KOH so it even acts as a preservative. The only problem with the reaction is it's slow to charge and discharge.
- polshaw 15y agoWhy is it that people have so many diverse opinions that aren't fully informed when it comes to energy?? It may have one benefit, but 30 seconds on wikipedia informs me that it requires 5 times the mass and 20 times the volume of lithium ion to give equal energy output. Which makes it a complete non starter for anything mobile.
- TheAmazingIdiot 15y agoFeNi batteries are a wonderful storage medium for things like solar cell chargers in a house, or a wind turbine setup. I never said this is going to be the next watch battery tech. And also, the fact is that the first cars were electric: they used various chemistries. And as I said above, Leno has a still working car that uses a NiFe battery: Cheap materials, low maintenance, not heavy metal (and nontoxic to boot). In fact the original recipe indicated making potash, putting it in distilled water, and filtering out the physical chunks of ash.
