No Worthless Battery After 200,000 Charges? Sign Me Up
Researchers just figured out how to make a rechargeable battery that has a much longer life than the lithium-ion ones we use now.By Leah Becerra | April 21, 2016
Your laptop's battery has been screaming to be replaced for months now, but that replacement isn't cheap. Which is why this new nanowire battery out of the University of California, Irvine, is so exciting.
Batteries like the one in your phone are lithium-based, and over time, they hold less and less of a charge. That's why your once new 10-hour laptop battery may now only last two hours.
Researchers were working on creating batteries with gold-coated nanowires, which are extremely thin and fragile but still highly conductive. But the problem with wires is they eventually break.
