A123Systems Introduces New Li-Ion Cells Designed for Hybrids and PHEVs

A123Systems introduced its automotive-class, large-format 32-series Li-Ion cells specifically designed for Hybrid Electric Vehicle (HEV) and Plug-in Hybrid Electric Vehicle (PHEV) use at the Advanced Automotive Battery Conference 2007 in Long Beach, California.

The 32-series lineup initially will consist of two cells with custom Nanophosphate electrode designs, based on the same proven chemistry as the mass-produced ANR26650M1 cell: the 32113 M1Ultra and 32157 M1HD.

A123Systems anticipates that the 32113 M1Ultra high power cells will offer industry-leading power by volume and cost-per-watt.  Designed to meet the requirements of HEV applications, the 32113 is currently designed into A123Systems’ programs with major US and European auto manufacturers.

The 32157 M1HD cell uses a higher-energy electrode design geared specifically for PHEVs, and should offer greater volumetric energy density and the lowest cost per watt-hour. Currently used in a Saturn Vue PHEV development program, the 32157 is designed to offer superior calendar and cycle life at high depth-of-discharge (DOD), as well as excellent power density for charge-sustaining operation.

Actual performance data is not yet available.

A123Systems says that it optimized the automotive-class lithium-ion cells to offer power, safety and life at price-performance targets that can enable the wider adoption of lithium-ion technology in the auto industry.  Wide power availability over a broad range of state-of-charge as well as exceptional endurance implies that systems with both cells will require minimal oversizing, allowing for lower overall systems cost.

The 32-series cells are designed with abuse-tolerance in mind and will deliver 10+ year and 150,000 mile projected life requirements in engineered automotive battery packs.

A123Systems developed its Nanophosphate chemistry with the assistance of the Department of Energy FreedomCAR program and is a result of more than $102 million in private investment.

The saft battery may have 10 to 20% more energy density. We don't know as the specs are not out.

But it is not a safe battery, and cannot deliver continuous 30C power. It cannot be fast charged. And most probably does not have 4000 charge cycle and 10 years of calendar life. It probably cannot handle -30 to +70 degrees temperatures.

From the data provided, these batteries seem to meet all of GM's specs for the VOLT. I'm sorry more info wasn't forthcoming, and would love to hear someone ask the VOLT battery pack evaluation team their thoughts.

LiFeBATT, Inc. makes a 40138 Large Format cell and offers LiFePO4 complete packs with BMS & chargers available this November on their website: http://www.lifebatt.com/

Their's are manufactured in Taiwan and use the patented Phostech Lithium materials exclusively. Their powder is the Hi-Power formula developed for the EV industry by the Phostech plant in Munich, Germany.

I would like to see some American/Canadian/British companies using the Thundersky Battery series (TS-LFP) cells from www.everspring.net - as the little 90 Ah cell can handle 3C continuous (270 Amps) and a 5C pulse (450 amps). the nice thing is they have cell sizes from 40 Ah, 60 Ah, 90 ah, 160 Ah, 200 Ah, 400 Ah, and even 800 Ah - all at 3.2V Nominal, so you can build a pack with just about the specific Volts/ Ah (Kwh) total that you need without any parallel cell arrangements - just all serial!
Note the faily consistant pricing of $2 per Ah at any cell size up to the 800 Ah cell which is $2.50 per Ah:
