That's the usual problem with many new tech stuff. Especially batteries. I've read of many new solutions, and then you never see it make it out of the lab. Even if something like this does pan out, there's no guarantee it will make it into the form factor we currently rely on, an 18650 battery. It would be great if it did happen.
This technology is intended for small and hand held devices. If it can't take the shapes those devices need it won't sell very well. For some reason Li batteries want to be small, even when they're supposed to deliver a lot of power, as in a car.
I read a peice some where that said, in effect, a nano tech super battery (how about energy density of liquid fuel) would be the biggest advance in mechanical engineering since steam power. Goodenough's work is not that but 3 times energy density, more recharges and faster recharging would change most hand held devices including ecigs. I would love to see him be the one. I'm a fan.
