Breakthrough lithium ion battery technology

A new lithium ion battery technology capable of operating at extreme temperatures without requiring thermal management was unveiled by A123 Systems this week.
 
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.
 
"By delivering high power, energy and cycle life capabilities over a wider temperature range, we believe Nanophosphate EXT can reduce or even eliminate the need for costly thermal management systems," said David Vieau, CEO of A123 Systems.
 
Unlike lead acid or other advanced battery technologies, it 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 the technology, which A123 expects will deliver a 20 percent increase in power at temperatures as low as minus 30 degrees Celsius.
 
 
Dr. Yann Guezennec, senior fellow at CAR and professor of mechanical engineering at the Ohio State University said, "If our testing also validates the low-temperature power capabilities that A123's data is showing, we believe Nanophosphate EXT could be a game-changing battery breakthrough for the electrification of transportation, including the emerging micro hybrid vehicle segment."
