摘要The temperature dependence of energy storage and charge–discharge properties of a lead–free 0.62Bi0.5Na0.5TiO3–0.06BaTiO3–0.32(Sr0.7Bi0.20.1)TiO3ergodic relaxor ferroelectric ceramic were investigated. The energy storage density was maintained ≥ 0.5 J/cm3up to 140 °C with a high efficiency ≥ 90%. The stored energy was released in sub–microsecond durations and charge–discharge performances were enhanced as temperature increased to 160 °C. This ceramic possessed an enhanced power density 18.2 MW/cm3and large current density 606 A/cm2. All results showed that this ergodic relaxor ferroelectric ceramics appeared very promising for pulse capacitor applications. © 2017 Acta Materialia Inc.
