A123 unveiled a new hybrid battery pack this week at the Advanced Automotive Battery and Ultracapacitor Conference in Baltimore. It could be appearing in vehicles within three years, says Ric Fulop, one of the company's founders and its vice president of marketing and business development. He also said that they could make hybrid vehicles cheaper and more convenient, while maintaining or improving performance. The pack, smaller than a carton of cigarettes, weighs about as much as a small laptop computer. Ten packs would replace the 45-kilogram battery in the Prius, Fulop says; and if one failed, the consumer could continue to drive the car using the remaining batteries, then replace the faulty one as easily as changing the battery on a rechargeable tool.
Because the batteries put a lot of power into a small, light package, a much smaller battery is needed to power the car, which could reduce hybrid prices. As a result, cars could come with a hybrid option that costs about as much as the option for an automatic transmission, Fulop says.
A123Systems has developed a new generation of Lithium-Ion batteries that uses proprietary nanoscale electrode technology to achieve unprecedented levels of power, safety and life. Their batteries use a nanostructured lithium-ion phosphate material, an advanced version of the type of battery used in laptops. The high power batteries are based on a safe and stable active material that can use particle sizes below 100nm without adverse reaction compared to the 5 to 20 microns particles used in traditional Li Ion batteries which were required to minimize safety risks inherent to first-generation Li-Ion chemistries. This new storage electrode enables much faster kinetics providing higher power than is possible from any other Li-Ion chemistry. To take advantage of the power delivered by this new chemistry, they have developed electrode and cell designs that provide the lowest impedance of any battery of its size, and a new electrolyte system that operates over a much wider temperature range.
Advantages Include:
- Up to 5x increase in power density vs competing technologies.
- Intrinsic safety
- Breakthrough improvements in life
- Operating temperatures from -30 degrees C to 70 degrees C.
- 5-minute charge time
The cells are intrinsically safe and eliminate the risk of explosions and thermal runaway associated with conventional Lithium-Ion batteries that use oxide active materials. To achieve this, the active materials in A123’s technology are not combustible and do not release oxygen if exposed to high temperature or in the event of battery failure or mechanical abuse. Their cells do not contain heavy metals and are environmentally friendly.
A123 operates a combination of wholly owned, state-of-the-art tier one manufacturing plants and subcontractor facilities in China, Korea, US and Taiwan.

Technology Review: More Powerful Hybrid Batteries, May 19, 2006
A123Systems, Watertown, MA
With their quick charge capability, these batteries could be a step in the right direction for future PHEVs and eventually, more practical EVs. Wonder what are the main reasons for the 2 to 3 years delay. Design limitations or integration problems to be solved?
Posted by: Harvey D. | May 20, 2006 at 12:07 PM
3 years will give enough time for the new technology to be killed. That's my guess on the delay.
Detroit and the exxon mob do not want plugin vehicles. Fortumately Subaru is already road testing the similar Hitachi battery.
A123 is an MIT related company. MIT is under the thumb of the dark forces of lord cheney of Halliburton. That is why A123 will not specify the kwh per pound stored.
That would make it obvious that liquid fueled infernal combustion should die.
Why is Toyota fighting a plugin Prius? Threats from lord cheney's men.

They don't give as much information as I'd like either (I suppose because patents are pending, competition, etc) but power density is stated on their website as >3000 W/kg in the battery comparison chart: http://www.a123systems.com/images/charts/techCompare.jpg

I wish Crackpot Conspiracy Theories, (CCTs) had a measurable btu content, aside from the associated hot air which apparently functions as a propellant. Lord knows that CCTs are cheap and abundant. If we had an efficient means to turn CCTs into electricity, it would be too cheap to meter. With cheap, plentiful CCT electricity, Alcoa could turn out more aluminum foil for hats.
Posted by: bde2200 | May 21, 2006 at 06:24 PM
Yes, power density is clearly stated, >3000 W/kg, but what about energy density, Wh/kg?

It's not funny earl! Hehehehey. Well laughing is better than crying.
But 3 YEARS!?! When US soldiers are trading their blood for oil? And even that is not working to control soaring energy prices that are devestating american families' finances.
And with the huge national debt rung up by these oil wars with the dollar now under attack as OPEC nations switch to euro dollars for oil trading.
Posted by: amazingdrx | May 22, 2006 at 09:02 AM
Here is my latest guess and the reasoning behind it. Around 250 wh per kg.

Eminently practical to replace liquid fueled infernal combustion with the 5 minute charge to 90% feature.
Now must I measure the size of a ciggarrete pack, plugin the density of the A123 battery, and compare 10 of them to the capacity of the Prius battery?
I guess so.
Posted by: amazingdrx | May 22, 2006 at 09:15 AM
Can anyone venture a guess as to how much more regenerative braking energy these fast recharge batteries can capture? And how that will affect the control system's discharge allowance point?
Posted by: hamerhokie | May 22, 2006 at 04:14 PM
I may be the pessimistic type, but one might suspect that A123 don't state the energy density of their batteries because it's bad.
10 packs of A123 = 1 Prius battery = 1.3kWh
1 pack of A123 = 1 "small laptop = at least 1.3kg (Sony Vaio, one of the smallest)
1.3kWh / ( 10*1.3kg ) = 100Wh/kg
Oh, and the volume of one A123 pack is the same as a cigarette CARTON, not pack... Guessing around 30cm x 8cm x 5cm the carton, that makes 1.2 liters.
0.13kWh / 1.2 l = 108 Wh/liter
OK, these are all guesses and approximations... Feel free to correct me if I'm wrong.
Posted by: Mitz | May 22, 2006 at 04:20 PM
Mitz: As most Li-On batteries have an energy density of 100 to 150 Wh/Kg; 108 would be in the low end. Li-Polymers are claiming 150 to 200 Wh/Kg and Electrovaya's as high as 280 to 300 Wh/Kg. Europositron is claiming 1330 Wh/Kg with their aluminium rechargeable battery but the prototype is not out yet.
Proven Higher energy density (above 300 Wh/Kg) seems to be the next challenge for all types of super batteries.
Posted by: Harvey D. | May 23, 2006 at 02:06 PM
Great info Harvey! The links would be useful for further blogerel if you have them.
I'm sure hoping for upwards of 300 wh/kg for the A123 and Hitachi nano-phosphare 5 min chearge to 90% lithium ions.
But electric plugin cars are still going to be competitive in terms of range and power with liquid fueled internal combustion at 250 wh/kg.
And even with 60 cents per gallon equivalent to the government in taxes, the electric plugin will be running at the equivalent cost of $1.35/gal. That is with electric rates of 10 cents per kwh.
With home or coop based renewable energy that cost can come way down from there. All the way down to zero, excluding the road taxes.
Now to get mass production and cost reduction for these new batteries, solar PV, and wind power, similar to the price drop in computer chips over the years.
Posted by: amazingdrx | May 24, 2006 at 12:58 AM
It is still difficult to get 'proven' energy density (Wh/Kg or Wh/litre) for the new Altair, Toshiba and A123 quick charge batteries.
If someone has the info, could you post-it?
Posted by: Harvey D. | May 24, 2006 at 03:21 PM
Going by this website it looks to be about 130 wh/kg for the A123 (if my math is correct). Mostly pictures but at least they post some battery stats.

hello all. first time posting to this blog. any blog, actually.
just thinking that you could get a good idea of energy density by hooking up one of those cordless tool batteries to some device with a known power drain and running it down to no charge. then take a nickel battery of the same type used in the prius and do the same for comparison.

off topic.
ok, sorry about this. i don't understand what url i'm supposed to put when posting and i think that caused the machine to label my post as being by jon. thatwas me, chris, posting for the first time. not jon. sorry jon.
Posted by: chris | December 23, 2006 at 04:23 PM
I'mm interesting to know how exactly A123 system operate on any car.Example if i have any car from 2000 model or up...can I install A123 system? .note: i speaking about no hybrid car..simple car,full injection,etc etc.
Thanks for you information.
Who sale the system.?
Posted by: carlos ramirez | August 18, 2007 at 01:18 PM
Carlos,
You are a dumb a55. A123 produces batteries. Hence you can not put them in your car, assuming that yours is petrol based. If you wanted to you would have to pull the whole drive system out and design and build an electric system. If you are not an Electrical or maybe Mechanical Engineer, then you dont have the skills to properly design a system. I have seen armatures build simple systems which worked but they are not really properly designed, hence dont use good or efficient components.
It would be better to just buy a hybrid or EV because they will cost less than if you attempt to make your own.
A123 sells the batteries.

5-minute charge time is very impressive. Is that for the whole battery and how far does it take a vehicle on electric power alone?

Our vehicle uses a hybrid battery pack. I am apart of Embry Riddle's Eco Eagles club. We are Embry Riddle's branch of the EcoCar challenge. We work to design, build and integrate solutions into an existing production vehicle. Solutions such as hybrid, plug-in hybrid and fuel cell drive train technologies will be explored.

see what i think might happen is that company's like exxon and chevron will be buying out this technology's and taking them out so they can continue business as normal

Buying a new car that consume too much gasoline can be a big matter, for most average people, it is important to buy a car that doesn’t consume too much gasoline, as it will help them to save a lot of money.
Posted by: Refuse Vehicle Repair | June 10, 2011 at 09:56 PM
Hybrid cars take less maintenance than ordinary cars.
That is because they don't have fuel based corrosion.
