Supercapacitors are an essential energy storage mechanism in self-powered systems. Their high-energy capacities combined with their ability to provide high-power output make them ideal for ultra-low ...

Left) Schematic illustration of a composite of CNTs and PANIs. It shows that the covalently bonded PANIs are evenly distributed among the CNTs and that each PANI can act as a nanoscale cell. (Right) ...

Supercapacitors provide a highly rechargeable energy source. Michael LaClair, Cooper Electronic Technologies, Boynton Beach, Fla. Building control systems use electric motors to drive valves and ...

How tailored chemical solutions provide the supercapacitor layers. How these solutions were 3D-printed onto a substrate, then folded to create the supercapacitor. How the final supercapacitor performs ...

Ultracapacitors store electrical energy through static charge separation in a double-layer of electrodes, instead of chemical reactions like in batteries. This allows them to charge and discharge ...

Supercapacitors are unique because they can work in conjunction with or as an alternative to batteries in applications needing many rapid charge/discharge cycles, and they are popular in applications ...
