Short battery life, is the number one complaint when it comes to smartphones and laptops. In a society free from wire, we don’t want the gadgets to stuck with the electricity to charge them. And while researchers are looking for ways to improve wireless charging, we could worry less about the battery itself receive an upgrade.
01. News from the world of science
Let us rejoice because the new technology promises just that! Distinguished University of California, Irvine, which invented the source of power, using the nanowire – it can be charged hundreds of thousands of times.
02. Amazing stuff
Nanowires have ideal characteristics for energy storage and transmission. They have a high conductivity and size is thousand times thinner than a human hair. This means that they can be arranged to provide more battery life. Unfortunately, nanowires, are very fragile and after repeated charging and discharging it goes unstable.
03. Scientific works
The researcher, whose experiments and conclusions were published in the American Chemical Society’s Energy Letters, decided the problem with the nanowires this way: they covered material dvuoksidom manganese and “swaddle” in plexiglass. This combination retains all the properties of nanowires but makes them resistant to fractures and other injuries. Mia Le Tay, principal investigator, charges and discharges the battery to 200,000 times without breaking its structure and without power loss. “Mia has first covered the nanowire with a very thin layer of Plexiglas, and then fixated process” – said the senior author of the project Reginald Penner, Head of UCI chemistry, in his statement. “She found that only with the help of this gel it could be repeated hundreds of thousands of cycle times without loss of capacity.” He added- “It was unbelievable Because the batteries tend to die rather a dramatic fashion after passing a maximum of seven thousand cycles.”
Researchers believe that a combination of Plexiglas as a gel and magnesium oxide in the nanowires provides flexibility and protects the structure, preventing the formation of cracks, thus extending their service life. Mia says- “This study proves that the manufactured nanowire battery can have a long service life. But what is more important – we can really make this idea a reality!”
