Team observes real-time charging of a lithium-air battery

One of the most promising new kinds of battery to power electric cars is called a lithium-air battery, which could store up to four times as much energy per pound as today's best lithium-ion batteries. But progress has been ...

Komaba Group reports sodium ion battery progress

(Phys.org)—Scientists with a common goal, to figure out an alternative to the lithium ion battery, the main power source of choice, are not giving up. The quarrel is not with the lithium ion battery's performance but in ...

Liquid batteries could level the load

The biggest drawback to many real or proposed sources of clean, renewable energy is their intermittency: The wind doesn’t always blow, the sun doesn’t always shine, and so the power they produce may not be available ...

Novel device removes heavy metals from water

An unfortunate consequence of many industrial and manufacturing practices, from textile factories to metalworking operations, is the release of heavy metals in waterways. Those metals can remain for decades, even centuries, ...

Nano bundles pack a powerful punch

Rice University researchers have created a solid-state, nanotube-based supercapacitor that promises to combine the best qualities of high-energy batteries and fast-charging capacitors in a device suitable for extreme environments.

A simple slice of energy storage

Turning graphite oxide (GO) into full-fledged supercapacitors turns out to be simple. But until a laboratory at Rice University figured out how, it was anything but obvious.

Upgrading the vanadium redox battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research indicates ...
