Microbatteries Could Recharge Phones Instantly

Wouldn’t it be awesome to plug in a dead smart phone and have it fully charged in under a second? The wait won’t be long now for that leap. A team of scientists just developed what they say are the world’s most powerful microbatteries capable of near-instant recharging.
Supercharged! Battery Power for the Future
The new batteries are made high-power lithium ion and are only a few millimeters in size. IInside, they contain a 3-D nanostructure made
from a thin film that was recently developed by Paul Braun from the University of Illinois at Urbana-Champaign. He describes his system as providing “capacitor-like power with battery-like energy.” Graduate student James Pikul and team leader mechanical engineering and science professor William King, came up with an anode for it and then the the researchers put it all together in a tiny package. Their article was just published in the journal Nature Communications (abstract).
The scientists say their rechargeable microbatteries can charge a thousand times faster than similar technologies. In addition, the tiny size means these batteries could give a ton more capacity to smaller electronics like medical devices, sensors, lasers, and a wide range of consumer electronics.
Even Batteries are Bigger in Texas
The prospect of almost instantaneous phone recharging is impressive by itself, but the engineers also told the university that a phone powered by these batteries could even be used to jump-start a dead car battery. Then they could be fully recharged after another second. Holy cow.
As with any new battery tech, there’s still a lot of tinkering left to do before microbatteries come to our electronic devices. The team says it will be integrating their batteries with other electronics components and figuring out ways they could be manufactured affordably. I cannot wait to not have to wait for my phone to recharge.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Bing Apps for Windows 8 get major updates

Late least year, Microsoft rolled out a half dozen Bing Apps for Windows 8 users, each one focused on a specific category, such as travel and sports. The apps were designed to offer “immersive vertical experiences,” and now, about six months later, a big line of updates for them is being pushed out. Users can grab the updates now by heading into the Windows Store and selecting the updates notification.
