"For cost-effective, reliable renewable energy technologies, we need better performing capacitor materials than what are available today," said Yi Liu, a senior scientist at Berkeley Lab who led ...

A new approach to materials engineering promises to overcome the limitation of capacitors commonly used in smartphones, displays and electric vehicles, according to a study published in Nature.… ...

It’s something that [Ben] had a need for, which he solved with a clever combination of PCB material and 3D printing. While the variable capacitors of yore invariably used intersecting vanes on a ...

Conventional supercapacitors often use an electrochemical construction, and activated charcoal is a frequent electrode material. The cement capacitor uses the property of cement curing ...

This work shows that very good results were obtained even with the use of local biomass; “it constitutes a cost-effective, sustainable alternative for improving conventional lithium-ion capacitors.

The Solid State and Materials Research Group has come up with a lithium ion capacitor using electrodes produced from wood particles that are discarded as waste in sawmills. This biomass is very ...
