Battery boost

Mesoporous titanium dioxide microspheres can improve surface features of the electrodes in lithium-ion rechargeable batteries allowing much faster charge-discharge cycles than is possible with conventional graphite electrodes. The work is yet another step towards making the next generation of rechargeable batteries for portable gadgets and electric vehicles. According to the developers at Oak Ridge National Laboratory in Tennessee, they can charge their battery to half capacity in six minutes while the traditional graphite-based lithium ion battery would achieve just 10% charge at the same current.
