I don't know if it's true or not. I talk with people that makes way more powerful batteries and the current one they have is capable of 400C continuous and can be charged in 2 minutes at 150A. Now they say fast charging may impact life of the cell, but they have done so far over 3000 cycles and this particular cell still have over 80% of its capacity. I just wish I could get my hands on a few .

I do believe there are advances in battery technology that are still in the beta phase testing phase.

I've had a few talks with one individual about a "AA" size Lifepo4 cell that the manufacturer claims a 1600mah capacity on.

This energy density is much greater than the former 450-500mah "AA" sized Lifepo4 sized cell.

If they can get the energy density this good, regular lipo chemistry may become a thing of the past.

There are 2 types of LiFe battery. One is the Power cell that has less capacity, but offers higher C rating. The other is the Energy cell that has more capacity, but offers very low C rating.

Aren't those the Ultra Capacitors that EESTOR has been working on for a few years now? They are working on those Capacitors for a company named ZENN Motors who make electric cars up here in Canada. (but they can't sell them in Canada Stupid Government). Judging by an article I read about the new crop of ZENN cars for 2010, I think they might have achieved their goal.

Here's a quote from the ZENN Motors website.
''The ZENNergy™ drivetrain solution promises to deliver energy storage packs that are
• one-tenth the weight and mass of lead acid batteries,
• capable of one million-plus cycles,
• able to be fully recharged faster than any electrochemical
*battery and deliver superior performance in extreme
*operating temperatures
• safe
• cost effective – lower cost than current Lithium Ion
*battery technology''

No, they are actual batteries being used by various military clients. I really don't know how ZENN will actually produce those as it seems a bit of science fiction to be honest. If they have such technology, it'll be worth a huge amount of money. It seems more like a scheme to get dumb investors to throw more money at them. Look at the companies getting grants from the US Government to make electric and/or hybrid vehicles. If it's actually a capacitor, it will be like any other capacitor we currently know of. I know of a company in Canada that actually has a few working capacitors and some have been used in 1:1 racing application. I plan to use those in my 1:1 race car as well. I can come up with juicy ideas as well and throw it in a website to milk investors for money, but why should I do that. The people I've currently spoken with about my 1:1 race car don't actually think its doable, but I know it is as the technology is already available now. I really should make some BS story, they'll probably fall for that.

Choose not to believe in it, that is your prerogative. The science fiction in question is called EESU from EEStore, which centers around a core of aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix. They filed for a bunch of patents that have recently been granted regarding this new technology.

Anyone can make a patent even for things that can never be made in our life time. I can go in there and look through the EEStore, BASF, Northrop Grumman, Philips and others alike and come up with my own. They also failed to produce a prototype to showcase the technology to some big names out there. ZENN is just dumping money into EEStore just incase they do make it work so they can make a huge amount of money with the technology. Risk capital or venture if you ask me. If they had something to show for, you would see some real investors going in and basically taking over the technology.

I think the British Columbia government has or will change the automobile act/regulations so cars like the zenn Could be driven on the Street of B.C..
