Behavior of the Double Layer in Nonaqueous Electrolytes and Nonaqueous Electrolyte Capacitors

Abstract

It was shown in Chapter 2 that considerable advantages accrue if double-layer capacitors can be operated at the higher voltages that can be realized if nonaqueous solutions rather than aqueous ones are used as the electrolyte. The advantage is mainly that substantially higher Gibbs energy, G, and also in some circumstances better power densities, can be achieved because of the relation G = CV 2 /2.
