I don't get why people still fall for the miracle battery announcement. Maybe it's because I am more interested in batteries than the average person, but I've seen dozens of vaporware battery announcements and see very little reason to believe that this is not one. Sure, it might be better in some dimensions, but it's almost certainly not the immediate revolution, because there is almost always some way in which these supposed miracle batteries fatally suck (life span, temperature sensitivity, energy efficiency, weight, self-discharge, volume, material cost, mass-producability). My view is pretty in line with Elon Musk's here: In the mid term lithium-ion batteries will keep being the best compromise. I'll really believe that a new technology is not vaporware when I hear Elon talk about or Tesla invest in it (this has happened with Maxwell capacitors, for example).
