AltairNano battery technology... - RC-Monster Forums

Hi guys, just wanted to post a little something on the new Altairnano Nanosafe battery.

-First, can charged to 90% in 6 minutes

-I hope you are sitting down, 15,000 cycles at 10C charge/discharge rates! :019: And guess what, they are still at 85% capacity retention then.
-They also have the same energy density as A123 M1 cells. ~100Wh/kg
-Apparently, they can discharge at almost 100C?!

-Another, works JUST as good at -30 degrees celcius as it does at 25 degrees, and can operate down to -50C

-Short Circuit - PASSED
-Forced Discharge - PASSED
-Over Charge - PASSED
-Over Discharge - PASSED
-Nail Puncture - PASSED
-Crush - PASSED
-Over Temp. (240C) - PASSED

I am going to get a hold of a few of these for testing hopefully soon!

Enjoy!

90% in 6 minutes? So how much mAh are these and how many thousands of Amps do they charge them at, hehe, a bit crazy charge times there.

Well, the A123 M1 cells can charge in 5 minutes at a burst charge method.

From what i know, the Altair's Nanosafe can potentially be charged faster than that... don't know for sure though.

Are these actually materializing? I first heard about them 6 months to a year ago, and this is the first I have heard about them since then.

They are picking up steam QUICKLY. Don't be surprised by next summer you can buy them for yourself for RC.

Maybe sooner, Boshart vehicles purchased $700,000 order of them for initial design testing this summer. So it shouldn't be long until the general public can buy them. I wonder if they will create a spin-off company just for RC like A123 Systems did?

We will see!

these look real promising ...and sound good as well

zeropointbug · 11.29.2006, 12:45 AM

Well, if you had a 5Ah pack at say 16 volts, you can charge the thing at 50 Amps! That would take up half (800 watts) of a typical household breaker.

This puts the fun into RC... worry free, freedom (6 minute charging), and insane amounts of durable power.

I still worry about safety charging at those Amps. Even if it is proven, it's a huge jump from how long it takes for todays batteries.

aqwut · 11.29.2006, 06:49 AM

cool... where are you gettin' these from?... these batteries sounds beautiful....

nbcaznmaster · 11.29.2006, 07:39 AM

PRICE!! PRICE!! cheaper than m1?

zeropointbug · 11.29.2006, 01:13 PM

LOL, well they don't have a price quite yet; hopefully they will be sampling them soon, because 'ME WANT!'

They do sound amazing though, this is exactly what we need for full scale electric vehicles, of which i am working on... check my signature.

aqwut · 11.29.2006, 01:28 PM

doesn't Japan have full scale cars and buses that uses something like these batteries?...

zeropointbug · 11.29.2006, 01:38 PM

Well, i have read that they do have some electric buses and a few electric cars, yes. I am certain that they don't use these batteries. The batteries that they do use is most likely from "ThunderSky" Lithium batteries.

Mitsubishi and Subaru have a few electric cars that will become available in around 2008. Mitsubishi has a four wheel/wheel motor Lancer Evo that has 50Kw per wheel for 200Kw total. NO transmission, this is the way to go! The car can do 0-60mph in, if i remember correctly, about 4 seconds. The Subaru R1e electric car can be charged in like 10 minutes, i have no idea what batteries they are using?!

Here's a link to a video from Yahoo Current Driver that features a car from Phenix Motor Cars that uses "NanoSafe" batteries.

Ya, i've seen all the videos to do with AltairNano batteries/ Pheonix Motors.

The nice thing about the Altairnano Nanosafe battery, is that they actually have a 'prismatic' cell format, which is the way to go for RC, and electric vehicles (however there are pro's and con's for both in EV's).

They also claim 4000-Watts/kg continuous, which is always nice ;)
Which usually means lower cell Impedance, which translates into better performance for RC cars.

It will be nice once batteries don't have any voltage droop under load, has a super flat discharge curve. Or maybe we will have the new Super capacitors that several companies are working on(~1,000,000 cycles, 10,000W/kg, etc.)

Or maybe we wont even be relying on energy storage, maybe we will have the so called "Zeropoint" or "Vacuum" energy being utilized? :) Imagine endless energy at hand.
