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 ...
Unlike slow and steady batteries, supercapacitors gulp up energy rapidly and deliver it in fast, powerful jolts. A growing array of consumer products is benefiting from these energy-storage devices, reports Chemical & Engineering ...
