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.

Five budget-friendly open source storage servers

Storage is essential for the enterprise: Data must be stored. Data must be retrieved. Data must be shared. Data must be secured. At the same time, storage must not consume the entirety of your IT budget. Fortunately, you can find effective solutions in the world of open source. Outside of cost effectiveness, one of the biggest benefits of these solutions is the ability to modify them to perfectly fit your needs. You can make minor changes or even roll your own storage solution based on one of these tools. If you want enterprise support and a "solution in a can" that will meet just about any enterprise storage need, you should turn to Red Hat or SUSE. Both Linux-based companies offer some of the most powerful enterprise-ready tools on the market. But if you'd rather get your hands dirty and craft something of your own—something that won't demolish your budget—these five open source tools are a great place to start. 1: ownCloud ownCloud ( Figure ...

Visa confirms Coinbase wasn’t at fault for overcharging users

Yesterday, we wrote that Coinbase customers were being charged multiple times for past transactions. While some speculated that the erroneous withdraws were down to a Coinbase engineering issue, Coinbase issued a statement saying it wasn’t liable for the duplicate charges. The blame, instead, rested with Visa for the way it handled a migration of merchant categories for cryptocurrencies, Coinbase said. While you can read my post yesterday for an in-depth description of what happened, the basic gist is that Visa refunded and recharged (under a different merchant category) a month of old transactions. Many users saw the recharge come through before the refund processed, making it look like they were double charged. Honestly, the issue was likely exacerbated by existing payment rails — it’s normal for refunds to take multiple days to show up on credit and debit statements. But here’s where it gets weird — this morning Visa issued a statement to some publications shifting the blam...

Use Cortana to define words for you in Windows 10

Microsoft’s Cortana has many uses including sending emails or checking the weather. One of the best uses though is a simple look-up feature for words and their definitions. Combined with the Hey Cortana voice recognition using Cortana to tell you quickly what a word means is a great hands-free tip. There are multiple ways to get Cortana to define a word. If you have Hey Cortana enabled you can simply blurt out your request: “Hey Cortana what is the meaning/definition of inchoate ?” “Hey Cortana define ubiquitously “ You can, of course, also just type in your request e.g “ define beatitude ” although this admittedly takes some of the speed (and fun) out of using the personal digital assistant. For many words, Cortana displays the definition within a card, and OxfordDictionaries or EncartaDictionaries powers it. Sometimes, if Cortana misunderstands you or does not have the definition, the assistant opens up a web page after performing a web search for...

Airbnb will open its Cuba listings to users outside the United States

Airbnb will now let travelers from outside the U.S. to book properties in Cuba after receiving authorization from the U.S. government, reports the Associated Press . Previously, only Americans were allowed to reserve the site’s Cuban listings . They will open to international users on April 2. Airbnb launched its Cuban operations in April 2014 , four months after the Obama administration revealed that it will begin to restore diplomatic relations with the Communist country . The historic policy change means that travel and trade sanctions will be lifted , which is expected to boost tourism to Cuba dramatically because Americans no longer need licenses to visit. In fact, President Obama is currently on an official visit to Cuba , the first president since Calvin Coolidge to do so. According to the AP, Cuba is currently Airbnb’s fastest-growing market, with about 4,000 homes added since it opened listings. Other travel businesses...
