A very happy accident occurred during Mya Le Thai's doctoral thesis research, which will greatly upset replacement battery suppliers everywhere. Lithium-ion batteries slowly lose the ability to charge fully and to hold that charge as they are used and recharged multiple times. There are several reasons why this occurs and her team of researchers were trying to find a way to avoid some of those reasons by using nanowires to store and transfer electrons. This method has not been very successful in the past as nanowires are very brittle and would degrade over time in the same way other solutions did. However, in what The Inquirer refers to as an accident, the team discovered that coating gold nanowires in a manganese dioxide shell and then placing it in a Plexiglas-like gel resolved that problem, their test battery has now been recharged over 200,000 times in the space of three months, with no measurable loss of total capacity or power delivery. Hopefully this technology does not end up patented and sitting on a shelf unused to ensure we still need to continually replace the batteries we use.
"RESEARCHERS AT the University of California at Irvine (UCI) have accidentally – yes, accidentally – discovered a nanowire-based technology that could lead to batteries that can be charged hundreds of thousands of times."
