Influence of polarization effect by electric field on energy storage

Based on the Devonshire theory, the E-induced effects of polarization, dielectrics, hysteresis loop, and energy storage are investigated. Numerical simulations confirm that the ferroelectrics with soft ferroelectricity with properties of small and E-sensitive polarization, abrupt decrease of dielectric peak with increasing E, sloped and slender hysteresis loop with central narrow when approaching T-c, and symmetry energy storage peak, much less than T-c, towards high temperature with increasing E, can be the candidate of high energy storage materials.
