Lead‐Free High Permittivity Quasi‐Linear Dielectrics for Giant Energy Storage Multilayer Ceramic Capacitors
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.

Capacitors used for energy storage Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is
