Local Atomic Disorder‐Driven Deep Relaxor State for Ultrahigh Dielectric Energy Storage With High Thermal Stability

Lead‐free dielectric ceramic capacitors are indispensable for advanced high‐power electronic pulse systems owing to their exceptional power density and rapid charge‐discharge kinetics. However, the simultaneous realization of ultrahigh recoverable energy density ( W rec ) and high efficiency ( η ), especially...

Local Atom Clusters Drive Supercritical Relaxor State in Lead-Free Dielectrics for Giant Energy Storage.

Perovskite relaxor ferroelectrics have emerged as the leading capacitive energy-storage materials in pulsed-power electronics and integrated energy systems. However, conventional relaxor design strategies encounter a fundamental trade-off, wherein increasing compositional complexity to suppress hysteresis typically wea...
