First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...

In the race for lighter, safer and more efficient electronics—from electric vehicles to transcontinental energy grids—one component literally holds the power: the polymer capacitor. Seen in such ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
