While we’re on a long trip or out for a long time, our phones and other devices soon run out of power, which is really very frustrating. That time we all think, “What if we have had a battery that’ll never die?” Well, I think someone heard us and have created such a battery, but my mistake.
Scientists have found a way to create everlasting batteries, with which one can charge and discharge hundreds of thousands of times without losing capacity. According to a paper, Mya Le Thai, a Ph.D. candidate at the University of California at Irvine played around with the technology of battery before fortuitously making this revolutionary discovery. Mya used nanowires, a wire with a thickness or diameter of only a few nanometers but not well known for holding charges this much.
But if a gold nanowire is coated in a manganese dioxide shell putting it in a Plexi-glass like gel, you’ll get a much stable product, which would be capable of being charged and discharged multiple times. The chairman of the Chemistry department of UCI, Richard Penner said how did this happen,
“She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity. That was crazy because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most”
The team worked for about three months to reach 200,000 cycles, still no loss of capacity. “The coated electrode holds its shape much better, making it a more reliable option, this research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality,” Mya said.
And everyone has already predicted that this result could lead us to a longer lasting battery for cars, spacecraft and other devices such as phones, tablets and many more.
