| 1 | Dielectric temperature stability and energy storage performance of NBT-based lead-free ceramics for Y9P capacitors显示文摘In this work,novel(1−x)(0.75Na_(0.5)Bi_(0.5)TiO_(3))-0.25Sr(Zr_(0.2)Sn_(0.2)Hf_(0.2)Ti_(0.2)Nb_(0.2))O_(3)-xNaNbO_(3)(NBT-SZSHTN-xNN,x=0.1,0.15,0.2,0.25)ceramics were fabricated.The influence of co-doping of NN and high entropy perovskite oxide(SZSHTN)on the phase structure,microstructure and dielectric properties of NBT-based lead-free ceramics was investigated.Dense microstructure with a grain size of~5μm is observed.When x=0.25,a wide dielectric temperature stable range of−35.4-224.3℃ with a low temperature coefficient of capacitance of<10%is achieved,fulfilling the industry standard of Y9P specification.Furthermore,excellent energy storage performance with recoverable energy density of 2.4 J/cm^(3),discharge efficiency of 71%,power density of 25.495 MW/cm^(3) and discharge rate<200 ns are simultaneously obtained,which shows great potential for high temperature capacitor applications. | Hongtian Li Shiyu Zhou Jianwei Zhao Tingnan Yan Yuxiao Du Huanfu Zhou Yongping Pu Dawei Wang | 2023 | Journal of Advanced Dielectrics2023，13，1： | 0 |
