The battery that could last a lifetime

University of California research team develops nanowire battery that's been charged over 200,000 times.


IRVINE, Calif. — Researchers at the University of California, Irvine, may have invented a battery that never dies.

The new technology is a nanowire-based battery that can be recharged hundreds of thousands of times. According to IFL Science, nanowires have several ideal characteristics for electric storage and transmission because they are highly conductive and thousands of times thinner than a human hair and cab be arranged across a larger surface area to allow electrons to transfer.

According to findings published in the American Chemical Society’s Energy Letters, the research team coated gold nanowires in manganese dioxide and insulated in a Plexiglas-like shell that keeps the incredibly fragile wires’ properties intact and fracture resistant.

The researchers told IFL Science that the combination of the plexiglas-like gel electrolyte and manganese oxide provides flexibility and structure to the nanowires to extend their operational life.

The battery has been charged and discharged up to 200,000 times without breaking the nanowires and without capacity loss.

    Interesting possibilities if this comes to fruition. I wonder how the eventual price, weight and energy density will compare to the current Lithium Ion Polymer batteries currently use to power electric bicycles and cars. Will the gold content affect the price so as to make it a non-starter? The last battery I purchased 4 years ago for my electric bicycle cost $650.00 Can and it weighs about 15 or 20 pounds.
