A123 Systems (Nasdaq: AONE), has introduced Nanophosphate EXT, a new lithium ion battery technology capable of operating at extreme temperatures without requiring thermal management. Nanophosphate EXT is designed to significantly reduce or eliminate the need for heating or cooling systems, which is expected to create sizeable new opportunities within the transportation and telecommunications markets, among others.

Unlike lead acid or other advanced battery technologies, Nanophosphate EXT is designed to maintain long cycle life at extreme high temperatures and deliver high power at extreme low temperatures. According to the testing performed to date at the Ohio State University's Center for Automotive Research (CAR) and the very low observed rate of aging, cells built with A123's Nanophosphate EXT are expected to be capable of retaining more than 90 percent of initial capacity after 2,000 full charge-discharge cycles at 45 degrees Celsius. CAR has also starting testing the cold temperature performance of Nanophosphate EXT, which A123 expects will deliver a 20 percent increase in power at temperatures as low as minus 30 degrees Celsius.

A123's Nanophosphate EXT technology is scheduled to enter volume production in A123's 20Ah prismatic cells during the first half of 2013. A123 is also evaluating plans to potentially offer Nanophosphate EXT across its complete portfolio of cell products.
