University of Texas team has found that using coaxial nanotubes can improve the performance of lithium-sulfur batteries (Li-S).They used Polypyrrole-MnO2 coaxial nanotubes to overcome obstacles to using Li-S batteries in commercial products. Prior research has shown that Li-S batteries would offer users of electronics more energy storage—as much as 5X that of lithium-ion batteries...

Researchers have developed a hybrid of a fuel cell and capacitor on a biocatalytic basis. With the aid of enzymatic processes, what’s known as a biosupercapacitor efficiently generates and stores energy. The trick: the enzymes are embedded in a stable polymer gel, which can store a large amount of energy. Generating energy and saving it with as little loss as possible is one of the major challenges for today’s society. Energy production and storage usually take place in different systems – which is inefficient. This is different in the new biosupercapacitor, which combines both processes.

A supercondenser has been developed that can be charged by the sun. It contains no expensive or hazardous materials, has patents pending, and it should be fully possible to manufacture it on an industrial scale. In the future we could have a completely new type of energy storage, charged by heat energy – eg during the day when the sun shines, or by waste heat from an industrial process. The heat is converted to electricity, which can be stored until it is needed.

Simply put, a supercondenser is energy storage: a type of battery that consists of an electrolyte of ions between two electrodes. The charge is stored next to the electrodes, most often in carbon nanotubes...
