BaZrO具有较高的储能密度。潜艇。3(BZ)-修饰的0.80Bi.潜艇。0.5Na。潜艇。0.5Ti.潜艇。3-0.20双。潜艇。0.5K潜艇。0.5Ti.潜艇。3(BNBK)无铅铁电陶瓷的常规固相合成。研究了(1-x)BNBK-XBZ的储能性能。一定含量的BZ可以通过提高击穿强度来提高BNBK的储能性能。最大储能密度W。1=0.73J/cm。供应。在0.96BNBK-0.04BZ中，当E=70kV/cm时，储能效率[ETA]=0.75，明显高于文献报道的BNT基含铅FE材料。它的储能密度在30-100℃的温度范围内表现出优异的热稳定性，这些特性预示着环境友好的(1-x)BNBK-XBZ陶瓷将成为储能设备的候选材料。
Large energy-storage density is observed in BaZrO. sub. 3 (BZ)-modified 0.80 Bi. sub. 0.5 Na. sub. 0.5 TiO. sub. 3-0.20 Bi. sub. 0.5 K. sub. 0.5 TiO. sub. 3 (BNBK) lead-free ferroelectric (FE) ceramics synthesized by conventional solid-state reaction. The energy-storage property of (1-x) BNBK-xBZ has been investigated. Certain content of BZ can enhance the energy-storage property of BNBK by enhancing the breakdown strength. The largest energy-storage density W. sub. 1= 0.73 J/cm. sup. 3 and efficiency of energy storage [eta]= 0.75 at E= 70 kV/cm are achieved in the 0.96 BNBK-0.04 BZ, which is significantly higher than that of BNT-based and lead-containing FE materials reported. Its energy-storage density exhibits the superior thermal stability with temperature range of 30-100 &# 176; C. Those properties promise that the environmental friendly (1-x) BNBK-xBZ ceramics are candidate for applications of energy-storage devices.
