Holy wow batman, Altair Nanotechnologies new batts.

In October, the company announced that, in ongoing testing, it has completed 15,000 deep charge/discharge cycles of its NanoSafe battery cells. The cells still retained over 85% of their original charge capacity after the 15,000 cycles.

This represents a significant improvement over conventional, commercially available rechargeable battery technologies that typically retain that level of charge capacity only through approximately 1,000 deep charge/discharge cycles.

Altairnano said that it tested the battery cells at 10C (6 minute) charge and discharge rates. They were deep charged and discharged—i.e. they were taken to 100% charge and 0% charge respectively during the 6-minute cycles. Although tests involved full charges and discharges, partial charging and discharging of the battery does not appear to impact the life or the holding charge capacity of the batteries—i.e. they exhibit no memory loss.

In theory, a 15,000 charge cycle life could translate into a battery that would last greater than 40 years if it was charged daily, as would be the case in an electric vehicle or plug-in hybrid electric vehicle environment. However, in practice, other wear and tear factors would realistically limit the actual life of the batteries to probably 20 years, according to the company.

As long as the cost doesn't approach $7-8k/kwh, we've got a winner! :thumbup:

Wow, could this be the holy grail of EV battery technology we've all been waiting for?

As long as NanoSafe isn't made of people I will be happy ;) .

Crossing my fingers and toes (on one set of hands and feet only)!

cfg83, that's what I'm hoping for! I think you should get a bigger motor MetroMPG, and it could be one fast/environmentally friendly neighborhood EV. Quarter mile in <12s. ;)

OK, but like, when? and how much? :confused:

I kind of had my hopes pinned on Firefly carbon foam batteries. Low end of the scale, yes, but 3x better than lead acid, and likely much more affordable than the fancy chemistries.

Will a Firefly Spark a Battery Revolution?
Giant Caterpillar has given birth to Firefly Energy and our EV World may never be quite the same again. But it’s a good thing.

They'd be cheap too. Make for practical small car conversion... You wouldn't happen to have the rest of the update text? ;)

Unfortunately, the military currently has a hold on the technology. We might see it in 5-10 years.

900 pounds of Firefly batteries would give my in-progress Triumph GT6 conversion 250 miles range at 65 mph. St. Louis to Kansas City or from St. Louis to Louisville on one charge.

I'm really pissed about Chevron shelving large size NiMH. This is the battery that made affordable, cheap to operate, long lived, high performance, long-range EVs possible, nearly 10 years ago.

Politics and the business profit line usualy controlls what we can do , not what is able to be done. :thumbdown:
