Penn State Materials Research Institute scientists have developed a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. The team’s results have been […]






Drexel University researchers have shown that their process for making carbon films and micro-supercapacitors will allow microchips to have their own power sources. The work is a culmination of more than half a decade of speculation, fabrication, modeling and testing by an international team of researchers led by Drexel University’s Yuri Gogotsi, PhD, and Patrice […]






An Oak Ridge National Lab (ORNL) team led by Parans Paranthaman has created flexible polymer carbon composite films as electrodes for supercapacitors. Using the technology developed at the Department of Energy’s Oak Ridge National Laboratory and Drexel University could have some of the 300 million scrap tires discarded each year in the United States alone […]






Georgia Institute of Technology researchers use a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid to develop a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. The press release asserts that if the material can […]






Researchers at UCLA’s California NanoSystems Institute (CNSI) have successfully combined two nanomaterials to create a new energy storage medium that combines the best qualities of batteries and supercapacitors. The new hybrid supercapacitor stores large amounts of energy, recharges quickly and can last for more than 10,000 recharge cycles. In one design at just one-fifth the […]
