Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that

The hot-press procedure, developed at Drexel, melts sulfur into the nanofiber mats in a slightly pressurized, 140-degree Celsius environment — eliminating the need for time-consuming processing that uses a mix of toxic chemicals, while improving the cathode’s ability to hold a charge after long periods of use.Credit: Drexel University In late July of 2008 a British solar plane set an

The European “Fast Charge” research consortium presented a prototype for a charging station with an output of up to 450kW. The new charging station is suitable for electric models of all brands with the European standard Type 2 variant of the widely used Combined Charging System (CCS), and is now available for use free of charge. A Porsche research vehicle with a

This LED bangle, including a lithium-ion battery, was made entirely by 3D printing.     Credit: American Chemical Society Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new

This image shows a new integrated solar flow battery with a 14.1 percent efficiency.       Credit: David Tenenbaum, UW-Madison Scientists in the United States and Saudi Arabia have harnessed the abilities of both a solar cell and a battery in one device — a “solar flow battery” that soaks up sunlight and efficiently stores it as chemical energy for

If you’ve ever used a smartphone for more than a year or two, you know that the lithium ion batteries degrade over time and refuse to hold a charge like they used to when they were new—but the reason why has been little understood. But research published today in Nature Materials could have a few answers. A group of researchers at Stanford

A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants. Rather than attempting to convert carbon dioxide to specialized chemicals using metal catalysts, which is currently highly challenging, this battery could continuously convert carbon dioxide into a solid mineral carbonate as it discharges.
