Aluminium Battery that Charges SmartPhone in Just 1 Minute

Most of us could not imagine our lives without Smartphone, but the most annoying part of Smartphone remains its battery life.

No matter how power efficient our device would be, the smart display, faster performance and several apps running on our phones end up consuming all of it.

Now, I am here just not to talk about all these problems that you are facing, but I am here to introduce you an ultra-fast-charging battery that can charge your Smartphone in as little as 60 Seconds.

Yes, you heard right! Recharge your battery in just 60 seconds means, 1 minute.

FAST BATTERY CHARGING TECHNOLOGY

Scientists at Stanford University in the U.S. have developed a prototype aluminium battery that charges smartphone to full capacity in just 60 seconds.

Researchers say that this new aluminium battery is long-lasting, flexible and cheap, and could one day replace lithium-ion and alkaline batteries used in used in millions of mobile phones and laptops today.

In addition to recharge phones much faster, the new aluminum-ion battery is also safer than the existing lithium-ion batteries, which likely catch fire, according to researchers.

"We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames," said Hongjie Dai, a lead author and professor of chemistry at Stanford.

"Our new battery will not catch fire, even if you drill through it."

HOW IT WORKS

The new, experimental, aluminium-ion battery made of aluminium and graphite — both are "quite cheap." Aluminum is used to make the negatively charged anode while graphite used as a material for the positively charged cathode.

The Graphite cathode and Aluminum anode along with an ionic liquid electrolyte cased in a flexible polymer-coated pouch. The team was able to generate around 2 volts of electricity, which is higher than the previous experiment with aluminium.

In a video demonstration (below), scientists were able to show how a couple of their prototype aluminum batteries are used to charge a smartphone "within a minute."

Now, a question just strikes in my mind. If aluminium-based batteries are so much fast and safe to use, then why didn't battery manufacturers use aluminium from the beginning?

7,500 RECHARGE CYCLES POSSIBLE

The aluminium-based batteries were tested in past as well. However, previous experiment with aluminium batteries lasted just 100 charge cycles while the Stanford aluminium-ion battery can withstand more than 7,500 charge cycles without any loss of capacity.

When compare with a typical lithium-ion battery that lasts around 1,000 recharge cycles, the aluminium cells are long-lasting.

"The grid needs a battery with a long cycle life that can rapidly store and release energy," said Dai. "Our latest unpublished data suggest that an aluminum battery can be recharged tens of thousands of times. It is hard to imagine building a huge lithium-ion battery for grid storage."

In short, aluminium-ion batteries could be a sort of Holy Grail for mobile devices in future that not only charge faster, but also have flexible form factors.

For now, scientists are still working to improve the voltage capacity of the new aluminium-ion battery because at the current, it only produces about half the voltage of a typical lithium-ion battery.

Phoenix OS is (another) Android-as-a-desktop

Google Android may have been developed as a smartphone operating system (and later ported to tablets, TVs, watches, and other platforms), but over the past few years we’ve seen a number of attempts to turn it into a desktop operating system. One of the most successful has been Remix OS , which gives Android a taskbar, start menu, and an excellent window management system. The Remix OS team has also generated a lot of buzz over the past year, and this week the operating system gained a lot of new alpha testers thanks to a downloadable version of Remix OS that you can run on many recent desktop or notebook computers. But Remix OS isn’t the only game in town. Phoenix OS is another Android-as-desktop operating system, and while it’s still pretty rough around the edges, there are a few features that could make it a better option for some testers. Some background I first discovered Phoenix OS from a post in the Remix OS Google Group , although I’ve also found mentions of th

South Korea aims for startup gold

Back in 2011, when South Korea won its longshot bid to host the 2018 Winter Olympics, the country wasn’t widely recognized as a destination for ski and snow lovers. It wasn’t considered much of a tech startup hub either. Fast forward seven years and a lot has changed. For the next 10 days, the eyes of the world will be on the snowy slopes of PyeongChang. Meanwhile, a couple of hours away in Seoul, a burgeoning startup scene is seeing investments multiply, generating exits and even creating a unicorn or two. While South Korea doesn’t get a perfect score as a startup innovation hub, it has established itself as a serious contender. More than half a billion dollars annually has gone to seed through late-stage funding rounds for the past few years. During that time, at least two companies, e-commerce company Coupang and mobile-focused content and commerce company Yello Mobile, have established multi-billion-dollar valuations. To provide a broader picture of how South Korea stacks

How ad-free subscriptions could solve Facebook

At the core of Facebook’s “well-being” problem is that its business is directly coupled with total time spent on its apps. The more hours you pass on the social network, the more ads you see and click, the more money it earns. That puts its plan to make using Facebook healthier at odds with its finances, restricting how far it’s willing to go to protect us from the harms of over use. The advertising-supported model comes with some big benefits, though. Facebook CEO Mark Zuckerberg has repeatedly said that “We will always keep Facebook a free service for everyone.” Ads lets Facebook remain free for those who don’t want to pay, and more importantly, for those around the world who couldn’t afford to. Ads pay for Facebook to keep the lights on, research and develop new technologies, and profit handsomely in a way that attracts top talent and further investment. More affluent users with more buying power in markets like the US, UK, and Canada command higher ad prices, effectively

So, when will your device actually get Android Oreo?

Google officially just took the wraps off of Android Oreo, but there are still some questions left to be answered — most notably, precisely when each device will be getting the latest version of the mobile operating system. Due to Android’s openness and a variety of different factors on the manufacturing side, it’s not an easy question to answer, but we’ll break it down best we can. First the good news: If your device was enrolled in the Android Beta Program, you’ll be getting your hands on the final version of the software “soon,” according to Google. Exactly what that means remains to be seen, but rest assured that you’ll be one of of the first people outside of Google to take advantage of picture-in-picture, notification dots and the like. No big surprise, Google handsets will be the first non-beta phones to get the update. The Pixel, Nexus 5X and 6P are at the top of the list, alongside Pixel C tablet and ASUS’s Nexus Player set-top box, which will be receiving the upgrade i
