Ultrahigh energy storage in superparaelectric relaxor

Energy storage in dielectrics is realized via dielectric polarization P in an external electric field E, with the energy density U e determined by ∫ P r P m E d P, where P m and P r are the maximum polarization in the charging process and remnant polarization in the discharging process, respectively (fig.
