This is like my gimmick at this point every time there's an extremetech.com battery article... Here is the much better/more-detailed article at GCC: http://www.greencarcongress.com/2012/08/cho-20120816.html http://www.greencarcongress.com/2012/08/cho-20120816.html To me the interesting part isn't that it charges so fast, there have been LTO chemistries that charge plenty-fast for a while, but that its density is nearly double. We're now seeing multiple labs and vendors producing 300 - 400 wh/kg results. Expectations even just a few years ago were that we'd only be in the 250 range by now (where tesla is at).
