Dual-functioning electrolyte improves capacity of long-life batteries

By - May 4, 2014 2 Pictures
The three main components of a battery's makeup: the anode, cathode and the ion-conducting electrolyte, have been long understood to serve separate, independent functions. A team of researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) is seeking to challenge this theory, experimenting with a dual functioning electrolyte that supplements the cathode to significantly improve the capacity and longevity of long-life batteries.

Hybrid anode quadruples the lifespan of lithium-sulfur batteries

By - February 20, 2014 1 Picture
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.

Pomegranate-inspired electrode could mean longer lithium-ion battery life

By - February 19, 2014 3 Pictures
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.

How to get the most battery life from your Android device

By - December 31, 2013 8 Pictures
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

New lithium/sulfur battery doubles energy density of lithium-ion

By - December 1, 2013 3 Pictures
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.

Review: TYLT Energi+ device-charging backpack

By - October 29, 2013 18 Pictures
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
