Polarization (P) and maximum applied electric field (E max) are the most important parameters used to evaluate electrostatic energy storage performance for a capacitor. Polarization (P) is closely related to the dielectric displacement (D), D = ɛ 0 E + P, where ɛ 0 is the vacuum permittivity and E is applied electric field.

Abstract. Electrochemical capacitors (EC) also called ''supercapacitors'' or ''ultracapacitors'' store the energy in the electric field of the electrochemical double-layer. Use of high surface-area electrodes result in extremely large capacitance. Single cell voltage of ECs is typically limited to 1–3 V depending on the electrolyte used.

Fundamentals of energy-storage capacitors. The stored energy-storage density W st, recoverable energy-storage density W rec and efficiency η in a capacitor can be estimated according to the polarization-electric field (P-E) loop during a charge-discharge period using the following formula: (1) W s t = ∫ 0 P max E d P (2) W r e c = ∫ 0 P
The energy-storage performance of a capacitor is determined by its polarization–electric field (P-E) loop; the recoverable energy density U e and efficiency η can be calculated as follows: U e = ∫ P r P m E d P, η = U e / U e + U loss, where P m, P r, and U loss are maximum polarization, remnant polarization, and energy loss,
