The researcher accidentally invented a battery that can work all his life

The short battery life that the gadget battery provides is a number one complaint when it comes to smartphones and laptops. As a wire-free society, we do not need to tie ourselves to the current charge of our gadgets, because it more and more seems an annoying nuisance. And while researchers are looking for ways to improve wireless charging, we could be much less worried if the batteries themselves got their upgrade.

News from the world of science

Let's rejoice, because the new technology promises this! Distinguished the University of California, Irvine, in which they invented a source that uses a nanowire at its core - it can be charged hundreds and thousands of times, and it will not even require replacement.

Awesome stuff

Nanoprovoda have ideal characteristics for storage and transmission of energy. They have a high conductivity and are thousands of times thinner than a human hair. This means that they can be arranged to provide a larger surface area for electron transfer. Unfortunately, nanowires are generally very fragile, and do not feel very well after recharging and discharging.

Scientific works

Researchers, whose experiments and conclusions were published in the American Chemical Society's Energy Letters, solved the problem of nanowires in such a way: they covered the material with manganese dioxide and "wrapped" in plexiglass. This combination preserves all properties of nanowires, but makes them resistant to fractures and other damages.

Miya Le Tay, the chief investigator, charged and discharged the battery up to 200,000 times, without disturbing its structure and without losing power.

"Mia first covered the nanowire with a very thin layer of plexiglas, and after the process was looped," said senior project author Reginald Penner, head of the UCI chemistry department, in a statement. "She found that only with this gel could she repeat the cycle hundreds of thousands of times Without loss of power. "

"It was incredible," he added, "because the batteries tend to die in a very dramatic way after a maximum of seven thousand cycles."

Forecasts

Researchers believe that the combination of Plexiglas as a gel and magnesium oxide gives flexibility to nanowires and protects their structure, preventing the formation of cracks, thus prolonging their service life.

"This study proves that a nanowire-based battery can have a long lifespan," Mia says. "But what's more important is that we can really turn this idea into reality!"
