Abstract

Abstract With the gradual promotion of new energy technologies, there is a growing demand for capacitors with high energy storage density, high operating temperature, high operating voltage, and good temperature stability. In recent years, researchers have been devoted to improving the energy storage properties of lead‐based, titanium‐based, and iron‐based multilayer ceramic capacitors (MLCCs). However, limited research has been conducted into MLCC development using NaNbO 3 (NN)‐based materials. In this paper, the successful achievement of excellent overall energy storage performance in a novel NaNbO 3 –(Bi 0.5 Na 0.5 )TiO 3 –Bi(Mg 0.5 Hf 0.5 )O 3 lead‐free MLCCs is presented. The disordered tilting around the…
