“IBM is unveiling progress and new partners for its lithium air battery technology, which it started working on back in the Summer of 2009 and which could one day be a commercial product perhaps in the 2020/2030 timeframe”
“IBM says its lithium air battery could have an energy density of 1,000 watt hours per kilogram, which is more than double the energy density of some of the most cutting edge lithium ion batteries out there …. It’s also five to ten times more energy dense than the basic lithium ion batteries on the market.”
