Nanophosphate EXT Said to Be ‘Game-Changing’

Massachusetts-based A123 Systems (NASDAQ:AONE) is talking up a “game-changing” lithium ion battery technology its says allows extreme temperature operation without requiring thermal management.

“Nanophosphate EXT,” the company says, “is designed to significantly reduce or eliminate the need for heating or cooling systems.”

“We believe Nanophosphate EXT is a game-changing breakthrough that overcomes one of the key limitations of lead acid, standard lithium ion and other advanced batteries,” CEO David Vieau said in a release. “We believe Nanophosphate EXT can reduce or even eliminate the need for costly thermal management systems, which we expect will dramatically enhance the business case.”

‘Unlike Anything We’ve Ever Seen’

Testing at Ohio State University’s Center for Automotive Research, A123 says, indicates that cells built with A123’s Nanophosphate EXT are expected to be capable of retaining more than 90% of initial capacity after 2,000 full charge-discharge cycles at 45 degrees Celsius – 113F. CAR has commenced cold-testing too, where A123 says it expects a 20% increase in power at temperatures as low as minus 30 degrees Celsius – minus 22F.

“Based on our analysis, the performance of A123’s new Nanophosphate EXT at high temperatures is unlike anything we’ve ever seen from lead acid, lithium ion or any other battery technology,” OSU-CAR senior fellow Yann Guezennec says in A123’s Nanophosphate EXT announcement. “Nanophosphate EXT maintains impressive cycle life even at extreme high temperatures without sacrificing storage or energy capabilities, especially as compared with the competitive leading lithium ion technology that we used on our head-to-head testing,” Guezennec said.

Guezennec too said that Nanophosphate EXT could be “a game-changing battery breakthrough for the electrification of transportation.”

A123’s Nanophosphate EXT technology is scheduled to enter volume production in A123’s 20Ah prismatic cells during the first half of 2013.
