Evolution of the electrochemical double-layer capacitor (EDLC).

In 1853, Helmholz first demonstrated the promising idea of an electrochemical double-layer capacitor (EDLC).

In 1913, Gouy and Chapman put forth the "diffuse layer theory".

In 1924, Otto Stern combined both Helmoltz and Gouy-Chapman theory to explain the capacitance:

qsolution = qHelmoltz + qGouy
1/C = 1/CHelmoltz + 1/CGouy

In 1957, at General Electric, Howard I. Becker...
