By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The ...
(PhysOrg.com) -- In an effort to develop wearable electronics, researchers have designed a new ultra-thin supercapacitor that has a capacitance that is six times higher than that of any current commercial supercapacitor. ...
Over the past century or so, human activities have led to the rapid deterioration of the environment on Earth, with detrimental effects such as climate change and a rise in atmospheric CO2. Many scientists worldwide have ...
New research by engineers at MIT and elsewhere could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery's two electrodes, ...

(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 ...
Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its nanostructure, making ...
