First of all, our good buddy Autoblog Sam is now writing for Hydrogen Forecast. Go Sam! Second, A123 Systems showed off their new "prismatic lithium-iron-phosphate cell" at the twenty-third Electric Vehicle Symposium in Anaheim, CA. This new battery cell was developed for General Motors' E-Flex development program, and that means it will wend its way into the 2011 Chevy Volt. Those of you in the snow belt will be happy to know that the the cells work in -40 degrees. For those living in the sun belt, they are good at temps as high as 120. What does that mean for those days in Vegas when it's 125 in the shade? We don't know. But we do know that these cells will be in Volt mules by 2008. [Hydrogen Forecast]
