Lithium-Ion Batteries for Hybrid Vehicles?

I think this may be the article...

It's such a shame GM stood up such production (of NiMH) possibilities for Americans in Troy Michigan!

Sorry 'bout that, I'm searching it now...

Lithium-Ion Batteries for Hybrid Vehicles?

Uhh, you sent me to a broken link...
Just how "limited" is the different kinds of battery techs? I assume NiMH has no production problems in an all electric world. Can Bolivia (and other countries) supply to that amount?

Lithium-Ion Batteries for Hybrid Vehicles?

I bought two small sla (5 Ah for solar lights). I let one drain down to 6 volts and it never worked again despite the fact it was brand new. The other one works great (being that I keep an eye on it).

As for the NiMH, I use 3 sets of 3 (for 3.6 and 6.9Ah) for a 5.5 volt 600Ma solar panel with Cree led. It charges to about 4.1 volts and discharges to about 3.3 every day for almost a year now. It seems (from this unscientific experiment) that they could be made not to deplete past 1.1 volts per cell. I also purposely drain em (other smaller solar leds) down just to see and they do still charge.

Why GM Is Ready for a Rebound

I bought a used (and beat up) F350 four door pickup. It just keeps on running despite few problems. All I do is change the oil and replace battery and alternator. I think I need to repack the bearings... My main issue with it is the door handles and such are breaking (after 15 years), that's it.

GM would be cool if it could build electric cars and small trucks based upon the NiMH battery in volume! Lithium ion is too expensive and don't last as long.

Isn't Obama spending for more powerlines...?

Lithium-Ion Batteries for Hybrid Vehicles?

I would think the NiMH is a better choice (if made in a large format) because it is much more rugged and lasts longer. It's only about half the energy density as the lithium, but so what. the ingredients for NiMH could never be in short supply... Or could they, I'm not sure?

Toyota Far Surpasses GM When It Comes to EV

After some casual googling, I have come to the conclusion that lithium ion is far superior in the way of charging and discharging efficiencies (given circuit protection), however (and this is a big "but"), they really are not as long lived, do not tolerate extremes and are more expensive. NiMH is still twice as light as lead acid and in my own experiments have actually been drained to 0 volts (Try that with other types). I connected the solar panel backwards on purpose and the battery pack still works (after modest charge) almost as if noth'n wrong happened that day!

Since lithium is so much more efficient (needed for renewable energy storage), we need them to become longer lasting and much cheaper than NiMH. This is supposedly what the national energy dude is up to!
