Long life-cycle batteries

A123 develops energy storage solutions, looking for the next generation battery. The goal is to solve several of the current flaws plaguing energy storage solutions today: energy density, temperature of operation and length of life cycle. Today, a little more than one month after the company reported some staggering first-quarter losses, they revealed their latest battery solution. They call their system "Nanophosphate EXT," and promise that it will offer a number of important improvements on current lithium-ion and lead-acid batteries, particularly in terms of temperature and life cycle. "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," says Dr. Yann Guezennec, a senior fellow at the Ohio State Center for Automotive Research, where the new batteries have undergone testing.
