Abstract 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 Tc, and symmetry energy storage peak, much less than Tc, towards high temperature with increasing E, can be the candidate of high energy storage materials. HIGHLIGHTS E-induced polarization effect is related with thermodynamic parameters of ferroelectrics. Peak of energy storage shifts to high temperature under high-E. Larger induced polarization is corresponding to higher energy storage.

电场极化效应对储能的影响

摘要 基于Devonshire 理论，研究了极化、电介质、磁滞回线和能量存储的E 诱导效应。数值模拟证实铁电体具有软铁电性，具有小而E敏感的极化特性，随着E的增加介电峰值突然减小，接近Tc时中心窄的倾斜和细长的磁滞回线，以及对称储能峰值，远小于Tc ，随着 E 的增加，朝向高温，可以成为高储能材料的候选者。亮点 E 诱导极化效应与铁电体的热力学参数有关。高辐射下储能峰值向高温移动。较大的诱导极化对应于较高的能量存储。
