Nanophosphate EXT – A123’s New Lithium Ion Battery Technology Promises Cooler Times

Did you ever stop to think why electric cars are more expensive than regular ones? Ok, it’s the technology, but what about it exactly? The answer lies partly in the heating/cooling systems of the car, an aspect A123 Systems is about to improve with its new automotive battery.

The Massachusetts-based company came up with Nanophosphate EXT in an attempt to allow lead-acid, standard lithium ion and other batteries to perform at very high temperatures (45° Celsius – 113 Fahrenheit) or very low ones (-30° Celsius – 22 below Fahrenheit). The above-mentioned batteries need coolant on a regular basis to keep off excess heat, which means cars get sucked up of energy and on-road range.

However, by implementing Nanophosphate EXT, thermal management systems that usually charge up the bill will become smaller or even redundant, since testing showed the battery can retain more than 90 percent of its initial capacity at 45 degrees Celsius (113 Fahrenheit). It also can deliver starting power at minus 30 degrees Celsius (22 below Fahrenheit). That means cars will get lighter, less complex and more market-competitive.

Among the applications deemed to benefit from this so-called “game-changing breakthrough” are EVs and the fresh segment of micro hybrid vehicles. Also, the timing couldn’t be better, since people wonder whether the EV investment will actually start paying back and, as a consequence, sales are far from steady.

On the verge of bankruptcy, A123 may very well get saved by the Nanophoshpate EXT technology.
