Water is emerging as one of the most intriguing fuels in energy research, not by burning it, but by harvesting the subtle ways it moves, flows, and carries charge. From molecule-sized devices that ...

As engineers race to develop potential replacements, a global team of researchers just took a step forward on one alternative: a water battery. While a lithium-ion battery is filled with flammable ...

Chinese scientists have created a new type of water-based battery that is more efficient at storing energy than standard lithium-ion batteries. The new battery type is also supposedly safer than ...

We've gotten pretty good at making batteries that hold a lot of power. Unfortunately, we've been less good at making ones that don't eventually corrode, catch fire, or poison the ground they end up in ...

Forward-looking: Researchers from RMIT University in Australia have developed a new type of battery that replaces hazardous electrolytic fluids with water. Further research and development is needed, ...

Researchers in China have pioneered a formula for a nontoxic "aqueous battery" that they say could last 10 times longer than today's best devices. What's more, the water battery achieves this epic ...
