John Goodenough, a University of Texas at Austin professor in the J. Mike Walker Department of Mechanical Engineering in the Cockrell School of Engineering, has won the Royal Society of London's Copley Medal, the world's oldest scientific prize. Already a fellow of the Royal Society, Goodenough has been honored for his exceptional contributions to materials science, including his discoveries that led to the invention of the rechargeable lithium battery used in devices such as laptops and smartphones worldwide.
If your iPhone X doesn't last all day anymore and you have to charge it all the time, you might have to replace the battery. In this repair guide, we'll show you how to get your iPhone back to life with a new battery. This repair can help if your iPhone X crashes during heavy use because the voltage temporarily drops, you can no longer charge it or turn it on, or the battery life is very low.
Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation's power grid and longer-lasting batteries in cell phones and laptops.
This guide instructs you to fully detach the display assembly; this is intended to prevent accidental damage to the display cables. If you feel comfortable removing the battery without putting undue strain on the display cables, you can skip the steps for detaching the display.
Many of us will own a lithium-ion power pack or two, usually a brick containing a few 18650 cylindrical cells and a 5 V converter for USB charging a cellphone. They’re an extremely useful item to have in your carry-around, for a bit of extra battery life when your day’s Hackaday reading has provided a worthy use for most of your charge.
Solid-state batteries, which use solids instead of liquids to ferry ions through their core, are attracting billions in investment, thanks to their potential for reducing battery fires.
