Breakthrough Battery: Potential Game-changer

A new lithium ion battery technology has been unveiled by A123 Systems that is said to operate at extreme temperatures without expensive and weighty thermal management systems.

The lithium ion battery technology, named the Nanophosphate EXT is able to overcome one of the key limitations of lead acid, standard lithium ion and other advanced batteries, rendering it a potential energy storage technology game-changer.

The Nanophosphate EXT is capable of delivering high power, energy and cycle life capabilities over a wider temperature range, possibly reducing or even eliminating the need for costly thermal management systems. The battery technology is also expected to dramatically enhance the business case for deploying A123′s lithium ion battery solutions for a significant number of applications.

The Waltham, Mass.-based company, which has a new factory in Livonia, Mich., said testing at Ohio State University’s Center for Automotive Research showed that cells using the new technology could retain at least 90 percent of their capacity after 2,000 full charge-discharge cycles at 45 degrees Celsius (113 Fahrenheit) while delivering 20 percent more power at temperatures down to -30 C (-22 F).
