近年来，陶瓷电容器由于其高储能性能和快速充放电能力而受到广泛关注。采用流延成型和叠层技术制备了（SrTiO 3 + 0.5wt%Li2CO3）/（0.93Bi（0.5）Na（0.5）TiO（3）0.07Ba（0.94）La（0.04）Zr（0.02）Ti（0.98）O（3））（STL/（BNT-BLZT））层状结构无铅陶瓷，并采用常规固相烧结法进行了烧结。结果表明，STL/（BNT-BLZT）多层陶瓷在1175 ℃烧结，在294 kV/cm下具有优异的充电能量密度为3.67 J/cm（3）和放电能量密度为2.72 J/cm（3）。此外，STL/（BNT-BLZT）多层陶瓷在100 kV/cm的电场作用下，在25 ~ 100 ℃范围内具有良好的热稳定性。这些结果表明，STL/（BNT-BLZT）多层陶瓷可能是一种有前途的无铅高储能应用材料。(C)2018 Elsevier B.

In recent years, ceramic capacitors have attracted much attention due to their high energy storage properties and fast charge-discharge capability. The (SrTiO3+0.5 wt%Li2CO3)/(0.93Bi(0.5)Na(0.5) TiO(3)0.07Ba(0.94)La(0.04)Zr(0.02)Ti(0.98)O(3)) (STL/(BNT-BLZT)) lead-free ceramic with layered structure was designed and fabricated via the tape-casting and subsequently laminating technique, and sintered by the conventional solid state sintering method in this study. The results reveal that the STL/(BNT-BLZT) multilayer ceramic sintered at 1175 degrees C with an excellent charge energy density of 3.67 J/cm(3) and discharge energy density of 2.72 J/cm(3) under 294 kV/cm. In addition, the energy storage properties of STL/(BNT-BLZT) multilayer ceramic also displays good thermal stability from 25 to 100 degrees C at the electric field of 100 kV/cm. These results indicate that the STL/(BNT-BLZT) multilayer ceramic may be a promising lead-free material for high energy storage applications. (C) 2018 Elsevier B.V. All rights reversed.
