In the current investigation, the CuO modified BaTiO₃ ceramics were prepared through the conventional electroceramic processing. XRD, XPS, and SEM have been employed to characterize the phases, valences of ions and the microstructures. The sintering behaviors of the prepared samples were performed using a dilatometer, and ceramics could be fabricated at lower temperature. The electric field and temperature dependent energy storage performance have been studied. The introducing of CuO is very effective to improve the energy storage density and the efficiency due to the formed double P-E loops. 0.5 wt.% CuO modified ceramic exhibited an energy density of 0.52 J/cm³, which is nearly twice of pure BaTiO₃ ceramic. The J-E loops of CuO modified samples indicated double domain switches, consistent with the double P-E loops.

温度诱导的双PE回路和低温烧结BaTiO 3基陶瓷的改进的储能性能

在当前的研究中，通过常规的电陶瓷工艺制备了CuO改性的BaTiO ₃陶瓷。XRD，XPS和SEM已用于表征离子的相，化合价和微观结构。使用膨胀计进行所制备样品的烧结行为，并且可以在较低温度下制造陶瓷。已经研究了电场和温度相关的储能性能。由于形成的双PE环，引入CuO对于提高能量存储密度和效率非常有效。0.5重量％的CuO改性的陶瓷表现出0.52J / cm ³的能量密度，几乎是纯BaTiO ₃陶瓷的两倍。该JECuO修饰的样品的环表示双域开关，与双PE环一致。
