Perspective on electrochemical capacitor energy storage

3. Electrochemical capacitor background. The concept of storing energy in the electric double layer that is formed at the interface between an electrolyte and a solid has been known since the 1800s. The first electrical device described using double-layer charge storage was by H.I. Becker of General Electric in 1957.
