Both the URL you referenced to below EV Batteries are being held hostage 04/11/2012 , and the URL of my post EVLN: Ford And Tesla Pushing Toyota To Adopt Li-ion Jul 20, 2013 are quite old.
And a lot of information on NiMH is either old and or out of date, including the Wikipedia listing found on a search https://www.google.com/search?q=NiMH+large+format+batteries http://en.wikipedia.org/wiki/Patent_encumbrance_of_large_automotive_NiMH_batteries#Current_status_of_the_Ovonics_battery_technology sez ... February 14, 2012 BASF acquired Ovonic Battery Company and has ownership of the NiMH patent. For a huge company like BASF, it would be no problem to tweak the NiMH design enough to get another patent, so although that search (above URL) did have some links wanting NiMH to be set free in 2014, it still may not. >From what I can tell, NiMH is currently being used in hybrid packs, with the reasoning being NiMH handles the higher amount of charges/discharges of a small kWh hybrid pack (~1 mile of range) more affordably than a small Li-ion pack, or so sez TMC. It looks like it is still going to be a wait-n-see effort if NiMH ever get s out of the grips of the legal tie-ups it has been put through. IMO I would not wait. A long time ago I had posted my interest in perhaps cheap China made NiMH batteries. But that did not happen. So, waiting, and waiting for cheap large format NiMH batteries to be made available for the public to purchase, may be a fruitless effort when there are more affordable large format Li-ion batteries available for the public to purchase now. {brucedp.150m.com} - On Thu, Mar 6, 2014, at 07:52 AM, Sean Korb wrote: > It's 2014 now... a magic date for NiMH large format batteries. > http://www.winonarenewableenergy.com/1/post/2012/04/ev-batteries-are-being-held-hostage.html > > Where are my cheap NiMH large format batteries?
