A shield around the anode made from graphite, a material that is used in lithium-ion anode...

Increasing the range of electric vehicles and improving the storage of renewable energy systems are two examples of the benefits offered by lithium-sulfur batteries. Though they can hold four times the energy per mass of the lithium-ion batteries used today, their considerably shorter lifespan has proven something of a roadblock. Researchers from the Pacific Northwest National Laboratory (PNNL) have now designed a lithium-sulfur battery with four times the longevity, bringing the technology that little bit closer to maturity.  Read More

The 'pomegranate' design reduces the surface area of the cluster to one tenth of the sum o...

Though the use of silicon in lithium-ion batteries promises a whole new world of energy storage, it also poses several problems to a battery's durability and overall performance. A new electrode design inspired by clusters of pomegranate seeds and developed by researchers at the Department of Energy's National Accelerator Laboratory (SLAC) and Stanford University, overcomes some of these obstacles, bringing lighter and more powerful batteries closer to reality.  Read More

The Power Pillow consists of a battery pack encased within a soft cushion that allows you to charge your smartphones and tablets while relaxing on your sofa. When not in use, the Power Pillow hides the battery pack in a safe, easily located place.  Read More

Here's some helpful tips for getting the most battery life from your Android device betwee...

If your Android device is powered on all of the time, you may well find that you run out of juice before the end of the day. Though batteries in such devices are getting more powerful, so are the features and apps that run on them. Since some of these features aren't needed all the time, they can be turned off until you need them. Here's a look at how to get more up time out of your battery by changing basic settings manually, and a look at a couple of battery saving apps.  Read More

Batteries. We buy them at the store, use them up, and throw them away without much thought. In reality, however, batteries are remarkably complex electrochemical devices that are continually evolving. The latest example of this comes from the Lawrence Berkeley National Laboratory, where researchers have invented an advanced lithium/sulfur (Li/S) cell that offers a unique combination of energy storage, power, recharge speed, and survivability.  Read More

The TYLT Energi+ backpack features a huge battery that can charge three devices at once

Not long ago, a backpack was a simple device, one made for carrying books, small personal items, and other stuff. Then, something changed, and backpacks started evolving. Now it's not at all uncommon to find a backpack that can actually charge the electronic devices within it. One such model is the Energi+ Backpack from TYLT, which I've been using for the past couple of weeks. It's not the first backpack equipped with a battery, but is it the best?  Read More

A Tesla Model S electric automobile, a model which recently won Consumer Reports' Top Scoring Car award and aced the NHTSA's crash rating system, caught fire yesterday in an incident near Seattle. Tesla's shares fell 6.2 percent on the day as a result of the incident.  Read More

MIT's high-performance membranelss flow battery could be used to store green energy for th...

Researchers at MIT have come up with a new design for a rechargeable flow battery that does away with the expensive and ineffective membrane of previous designs. The device could prove the ideal solution for effectively storing energy from intermittent power sources such as solar and wind power.  Read More

The Astro3 12,000-mAh external battery from Anker

Having your smartphone battery die on you just when you need it most has to be one of today's top annoyances, particularly when you're miles from a wall socket. Anker has just released a pocket-friendly backup battery pack with enough juice to charge up most modern phones six or seven times before needing a refill. The Astro3 sports three USB output ports, one of which can auto-identify the connected device and charge it at its full speed.  Read More

The silverback-gorilla

In its travels, portable power system manufacturer Powertraveller says that it's come across the question many times: "Can you make a battery with enough charge to run a laptop all day?" It now has an answer. The silverback-gorilla is its beefiest portable power pack yet.  Read More
