Historically, multilayer ceramic capacitors (MLC''s) have not been considered for energy storage applications for two primary reasons. First, physically large ceramic capacitors were very expensive and, second, total energy density obtainable was not nearly so high as in electrolytic capacitor types.
Currently, energy storage ceramics with higher energy densities and lower costs [12,13] are widely used in aerospace [14], m ilitary [15], oil drilling [16], and various appli- cations.
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production.
