A new type of dual-functioning electrolyte developed at ORNL could result in an improved c...

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.  Read More

Yu Wang and Katie Zhong, with their gum-inspired electrolyte

Although high-capacity lithium batteries make many of today's mobile electronics possible, they do have one flaw – they occasionally catch fire. This can happen when they overheat, and their liquid acid electrolyte ignites and leaks out. Now, however, scientists at Washington State University have created a gummy electrolyte material that could make such fires a thing of the past.  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

Photoelectrochemical (PEC) cells can use sunlight to sustainably split water into hydrogen and oxygen, but efficient PEC materials tend to corrode rapidly in use. A Stanford research group has been studying this problem, and has found that depositing a thin layer of nickel atoms on a silicon PEC electrode allows it to operate for over 80 hours with no sign of corrosion.  Read More

Beer and sports are long-time cultural partners  (Photo: Shutterstock)

Beer is often quaffed in the aftermath of a day of sports in the fellowship of friends and neighbors. Unfortunately, while it may pick up the spirits and increase the celebratory feeling, the dehydration associated with alcohol consumption can lead to tiredness and cramping muscles. A new study by a group of Australian Public Health researchers shows that many of these ill effects can be lessened by adding a pinch of sodium to your beer.  Read More

Researchers are building an all-solid Li-S battery that is cheap, safe, durable, and store...

Researchers at the Oak Ridge National Laboratory (ORNL) have come up with a promising design for a lithium-sulfur rechargeable battery that is considerably cheaper and energy-dense than standard lithium-ion. Using a solid electrolyte rather than a liquid one, the battery is also testing much safer and more durable than previous designs.  Read More

The GH-LED10WBW is intended for use in emergencies, and for recreation

Every now and again, a rumor crops up that someone has invented a motor car that runs on water. Sadly, that still remains a rumor, but Green House Co Ltd of Japan will soon be marketing an LED lantern that runs on saltwater.  Read More

DARPA's proposed batteries would be smaller than these grains of salt (Photo: Mark Schellh...

As development of micro- and nano-scale devices continues to advance, so does the need for an equally-tiny method of powering them. There’s not much point in developing a surveillance micro air vehicle the size of a housefly, for instance, if it requires a watch battery in order to fly. That’s why DARPA is funding a project to create really tiny batteries. Just how tiny are we talking, here? Well, they’re aiming for something smaller than a grain of salt.  Read More

Researchers identify new low-cost catalyst for hydrogen production

To make sunlight practical as a dominant source of energy a viable storage technology needs to be developed. One promising area of research is imitating the process of photosynthesis to separate the hydrogen and oxygen atoms in water to create hydrogen fuel. An MIT team led by Daniel Nocera is now reporting that nickel borate can efficiently and sustainably function as the oxygen-producing electrode in such a process bringing the dream of energy storage systems that would allow buildings to be completely independent and self-sustaining in terms of energy.  Read More

The test vehicle into which researchers are integrating a redox flow battery

German researchers say a new type of electric vehicle battery that runs on electrolyte fluid can be recharged as easily as refilling a petrol tank. When the redox flow rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid.  Read More
