The 'Biode' saves power by eliminating the need for AC/DC conversion.

It just wouldn’t be a military technology show without a few drones on display.

To investigate the vastly unexplored oceans covering most of our planet, researchers aim to build a submerged network of interconnected sensors that send data to the surface — an underwater...

Researchers have 3D-printed an all-liquid device that, with the click of a button, can be repeatedly reconfigured on demand to serve a wide range of applications from making battery materials to screening drug...

Improvements to a class of battery electrolyte first introduced in 2017 — liquefied gas electrolytes — could pave the way to a high-impact and long-sought advance for rechargeable batteries:...

Your new industrial electronic product has been designed and the board components specified. It has been prototyped, either on a development board to check...

Semi-Liquid Metal Anode for Next-Generation Batteries

Researchers from Carnegie Mellon University have developed a semi-liquid lithium metal-based anode. Lithium batteries made using this new...

A reader asks an industry expert why adhesives are a better option for battery assembly in electric vehicles.

Certain species of bacteria that exist in oxygen-deprived environments must find a way to breathe that doesn't involve oxygen. These microbes — which can be found deep within mines, at...

Lithium-air batteries are poised to become the next replacement for currently used lithium-ion batteries that power electric vehicles, cell-phones, and computers....

Today's lithium-ion batteries use cathodes (one of the two electrodes in a battery) made of a transition metal oxide. Batteries with cathodes made of sulfur are considered a...

The National Energy Technology Laboratory (NETL) is a U.S. Department of Energy (DOE) national laboratory — with sites in Anchorage, AK; Albany, OR; Morgantown, WV; and Pittsburgh, PA...

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...

Our readers ask: How do you know that you have the right anode? How can you inspect the electrolyte or electrode material?

Many of the technologies we use today – space blankets, hearing aids, food packaging – began on the Apollo 11 mission.

Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

By capping liquids with graphene (an ultrathin sheet of pure carbon), researchers can easily image and analyze liquid interfaces and the surface of nanometer-scale objects...

Heavy-duty trucks, such as the 18-wheelers that transport many of the world's goods from farm or factory to market, are virtually all powered by diesel engines. They account for a...

It's dark on the back road as a motorist speeds toward the intersection. Up ahead, the stop sign blends with the night and in seconds a deadly crash occurs. According to the U.S....

Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To...
