New litihium ion battery breakthrough that allows batteries to be 2,000 times more powerful, recharges 1,000 times faster. |

Damn, that's awesome. Can't wait for it to get to consumer market. |

It looks interesting, but I need to read the paper. They have what look to be a number of different morphologies, and from the last figure, they have wildly different performances- from even current and power densities, to almost no current density and a high power density. |

The vast majority of battery usage takes place within ten feet of a wall outlet. Batteries are an overused technology. |

Why is the first technology that jumps to MY mind-- hand lasers? |

Batteries have terrible cost efficiency compared to grid power. In addition, the environmental impact of both production and disposal is tremendous. For the vast majority of terrestrial mobile devices, we are better served developing means of transmitting electrical power without wires than improving energy storage devices. |

Woot! May product development and commercialization rapidly commence. |

I have to mention that I also really like basing this on Lithium.... When our natural supply of it is pretty much gone. |

So... wouldn't a battery that's this much more efficient greatly reduce this problem? |

When I say cost efficiency, what I mean is the price to put a Joule of energy on the battery. A battery is piss-poor in this arena, such that a monumental gain in efficiency would be needed to make it simply "bad." These batteries are still lithium-ion batteries, operating on the same chemistry as the ones we already have. They just possess more surface area to allow more of those chemical reactions to take place. It is certainly the case that the faster charge time will increase efficiency by having less time in which the battery heating up and bleeding off heat, but you still have to overcome the energy barrier to reverse the chemical reaction that moves charge during the discharge cycle. The new battery holds more Joules of energy, and can receive them faster, but you have to pay for each Joule that goes in. Not only that, but you are still constrained by the efficiency of the grid itself, because that's where you pull your energy from. |

And if we could just figure out teleportation, it would solve our oil and traffic problems too. Except teleportation, by our current understanding, would break the laws of physics, while wireless power transmission is a reality now. Furthermore, Nikola Tesla had figured out how to do it well over a century ago. |
