Two New Cells From A123...

[xyster]

I didn't find any specs, and they don't specifically say it's lithium phospate like the M1. Does anybody know anything else about these?

32 Series Automotive Class Lithium Ionâ„¢ Cells: A123Systems recognizes that the impending transportation revolution requires industry-specific solutions. To that end, we have developed two Automotive Class Lithium Ion cells, the ultra high power AHR32113M1Ultra and the more energy dense AHR32157M1HD.

These two cells, designed for HEV and PHEV applications offer extremely low cost per Watt and Watt-hour, respectively.

The AHR32113 uses the new Ultra electrode design, offering yet higher power over that seen in the traditional 26650M1.

Alternatively, the 32157 uses a more energy dense electrode, geared for the higher energy requirements of the PHEV marketplace, while not sacrificing the power capability needed for charge-sustaining operation.

Contact us if you are designing HEV or PHEV solutions to find out how our 32-series Automotive Class Lithium Ion cells can enable your application.

Hmm.. now that's interesting.

I know Andy from FalconEV has 2 types of LiFe available with similar High Power or High-Cycle .. verrrry interesting.

They showed up on the a123 site about two months ago. So far I've dug up the following info but I havent read official specs. I dont know if this is accurate.


AHR32113M1 32mm x 113mm, 7000mAh capacity

AHR32157M1 32mm x 157mm, 10000mAh capacity

So for us silly, metric-phobic Americans, assuming those specs are correct that's 1.25" diameter X 4.45" length for the 7ah cell and 1.25" diameter X 6.18" length for the 10ah. Oooohhhh.... the 10ah cells would nicely fit my 7" X 9" X 3" boxes, and those cool terminals wouldn't require solder!

I hope and wonder if they will offer developer packs for these !!!! God Bless

 

[xyster]

Yes, developer's packs would be good. It might be hard to buy these cells in ebike-sized lots otherwise.

Gettin' better all the time... These would make a really neat array all bolted together in a 5 kWh pack. Just curious though, does anyone know why they're cylindrical rather than prismatic? Is it the simplest way to construct them or is it to allow air cooling, or both?

First time poster here. This topic really grabbed me, since battery size, weight, cost, and durability seems to be the biggest limiting factor in e-bike performance. Here's a press release on the "32 Series Automotive Class Lithium Ionâ„¢ Cells" that was mentioned earlier.

A123 Systems appears to have claimed 10 years/150,000 miles for these cells in automotive applications. Also of note is a claim that the "more energy-dense" AHR32157M1HD will feature a high depth of discharge.

Can't wait to find out the true stats on these. So far, per v-tach, it sounds like there's rumor as to the AmpHours being between 7-10 aH, but no info on the voltage that I've been able to find.

There was a mention & a picture of one of them in the May issue of Popular Mechanics.

Since these are individual cells the physical size has no bearing on the voltage, same volts as the M1's 3.3V.

So finally we get threaded bolt on terminals.
An advanced piece of technology that's a standard option on SLA's.
Even better than prismatic, if we can only get that other SLA innovation to maximize scarce real-estate with active material, the solid brick form factor.
I'm still waiting on Nilar to actually produce Nimh bricks, so hoverbikes will probably be available b4 that happens.

 

[Deepkimchi]

Y'all killin' me. Getting ready to order about $ 500 worth of Li-Po4 and y'all start dangling the new stuff in front of my nose.. :lol:

10 ah a cell ? Heck we could stick em in a metal tube like a giant flashlight. 8)

<A HREF="http://www.iloveebikes.com/batteries.html">Batteries with 10Ah LiFe cells</A> are already being made in china.
Actually getting them is a different matter.
But if anyone cares to contact them, let us know what sort of claims they make on price & availability.

 

[v_tach]

I'm betting the newer a123 cells will be difficult to come by given the target use. I doubt we'll see developer packs but we can always hope.

We might have to wait years for salvage packs to show up on Ebay, or pool resources to buy a large lot. At least there will quickly be Chinese knock-offs -- here's hoping they're of acceptable quality.

 

[Doctorbass]

I just can't imagine the next new Dewalt 36V 10ah drill that will come with those new A123 cells...

...and the only way to get those at cheaper price... :lol:

[CGameProgrammer]

These are M1s; look at the end of the model names. One is the "M1 Ultra", the other is the "M1 High-Density".

 

[Rebel with a cause]

Just what we've been waiting for! These are really sized more for ebike use than any other application. A 10 kwh pack for an electric vehicle, without paralleling, would need to be 1000v! But a ebike battery pack could be a much more reasonable 72v without the need to parallel cells, and therefore a much more simple BMS could be used. Now we just need to get them to sell in small quanitites and i've found my pack

 

[Rebel with a cause]

Also, any reason they couldn't make these in...say....50 or 100ah bricks?

 

[fechter]

Thundersky has the 100ah bricks, so there's no technical reason I can think of.

These look like the best batteries I've seen so far. I just hope the price comes down.

 

[tomv]

I sent email to a123 asking about their new 32 series cells. They do look like a perfect fit for e-bikes. Surprisingly I got a response from them the next day. The bad news is that they don't plan to sell those cells to anybody except car companies until late 2008. More detailed specs should be out some time this year though.

 

[europa81]

Any news here ? I mean ... even cars need spare parts some day.

 

[swbluto]

I get the feeling the battery system can only be "officially repaired" at certified repair centers given the technical nature of the batteries and the seeming easiness of a casual user to really screw things up which could risk a123's name.

 

[liveforphysics]

It's not about repair. Everything has crashes. When It does, we will find them in auto wrecking yards.

 

[swbluto]

Yes, only two to three years away. By that time, I would expect a123 to start integrating the ultra-high-discharge/charge rate technologies into its batteries which would have a major impact on regeneration feasibility and efficiency(read: Most of the energy needed to bring along just has to be squandered on air friction and rolling friction.). In the future, given that battery prices remain so high, I have a feeling this would definitely sweeten the hybrid pot for city dwellers as you wouldn't need too much energy capacity to store the car's kinetic energy and so the battery cost would be minimized.
