Those eggs you might have had for breakfast? They're not just food -- they may be the key to longer-running batteries in your devices. Scientists at MIT and Tsinghua University have developed a nanoparticle battery electrode whose egg-like design is built to last. Their invention, which houses a s...

Tesla's battery-focused "Gigafactory" isn't even finished yet, but that isn't stopping the electric car maker from expanding its plant's territory. The company just confirmed that it has nearly tripled its Nevada land purchases, adding 1,893 acres to the 1,000 it got back in 2014. Not that Tesla i...

Apple's recently changed the terms of its AppleCare+ extended warranty program. Now, no matter what iOS or OSX device you own (yes, even the Watch), Apple will replace the battery as soon as it hits 80 percent health. That's up 30 points from the previous 50 percent threshold for iOS devices. What...

Quite a few smartwatches are round, so why are they still using rectangular batteries? LG Chem certainly doesn't think that makes sense. It just started shipping a hexagonal battery that should deliver 25 percent more capacity in circular watches, where a lot of space normally goes to waste. You...

Don't like that your Galaxy S6 conks out before you're finished for the day? Samsung might offer some relief in the future. Its scientists have developed lithium-ion battery technology that promises much longer-lasting power packs. They use a silicon anode (which promises much more capacity than a...

Thanks to a slew of updates, IFTTT's automation apps just became decidedly more useful -- especially if you're religious about your smartphone's battery. If for Android now includes a battery channel, so you can tell your phone to perform certain duties depending on your charge state. You can have...

Tent? Check. Sleeping bag? Check. Spare battery packs to stave off the fear of being disconnected from the grid? Double check. Earlier this month, I loaded up the aforementioned gear for a quick weekend camping trip. It was honestly more glamp than camp, since we drove right up to our spot in Toll...

Sure, you can make solar-powered devices that store their excess energy in a battery, but what about the battery itself? Unfortunately, it's still behind the times -- the lithium-ion cells you see today have to be connected to another device to charge, and they're occasionally very dangerous than...

Lithium-based batteries' tendency to overheat and catch fire has been keeping back the development of promising new technologies. In particular, it's been affecting R&D of lithium-sulfur and lithium-air batteries, both of which are much lighter than current options and can store 10 times more...

Used to be that the only time your lithium-ion batteries changed their shape was when they were about to explode in an airliner cargo hold. But thanks to the ingenuity of an Arizona State University research team, future power packs could not only bend but stretch up to 150 percent of their origin...
