To achieve the miniaturization and integration of advanced pulsed power capacitors, it is highly desirable to develop lead-free ceramic materials with high recoverable energy density ( W rec ) and high energy storage efficiency (η). Whereas, W rec ( 80%. The results indicate that (1– x )ST- x (BNT-BLZT) lead-free ceramics can be used for pulsed power capacitors and open up a new research of ST-based ceramics.
