Anyone heard any more about this than this article. Sounds like they are through the sciency phase and actually able to produce usable batteries with this technology. Ilon Musk must be trying to buy this technology already. If any of this is true it would be a revolution. Lithium based batteries that have good energy density and don't catch on fire would be a good evolution. Getting much higher density maybe without housings for safety would be a nirvana. And if the costs were better or on par then they would have no competition.
