Scientist of Indian origin builds battery in a nanowire

The world at large runs on lithium ion batteries. New research at Rice University shows nano worlds may soon do the same. Pulickel Ajayan of the Rice lab has packed an entire lithium ion energy storage device into a single nanowire. The study was published in Nano Letters, the American Chemical Society journal. The researchers described testing two versions of their battery/supercapacitor hybrid. The first is a sandwich with nickel/tin anode, polyethylene oxide electrolyte and polyaniline cathode layers and the second packs the same capabilities into a single nanowire.
