Preview Abstract
In this work, a traditional solid-state method was adopted to prepare dense Ba $_{0.85}$ $_{0.85}$ Ca $_{0.15}$ $_{0.15}$ [(Zr $_{0.1}$ $_{0.1}$ Ti $_{0.9}$ $_{0.9}$ ) $_{1 - x}$ $_{1 - x}$ –(Nb $_{0.5}$ $_{0.5}$ La $_{0.5}$ $_{0.5}$ )_x]O₃(BCZT–xNL) lead-free relaxation ferroelectrics with excellent energy storage performance (ESP). Remarkably, a large breakdown field strength of BDS ( $\sim 410$ $\sim 410$ kV/cm) resulting from decreased grain size by double ions doping at the B-site was achieved in BCZT–xNL ceramics. Especially, the BCZT–0.12NL ceramic displays a good recoverable energy density ( $W_{rec}$ $W_{rec}$ ) of 3.1J/cm³, a high efficiency of 86.7% ( $η$ $η$ ) and a superior fatigue resistance, as well as a superior charge–discharge performance ( $C_{D} \sim 1623.14$ $C_{D} \sim 1623.14$ A/cm², $P_{D} \sim 162.31$ $P_{D} \sim 162.31$ MW/cm³, $W_{D} \sim 1.30$ $W_{D} \sim 1.30$ J/cm³, $t_{0.9} \sim 49.6$ $t_{0.9} \sim 49.6$ ns) and good thermal stability. Besides, upon NL doping, the FE to RFE phase transition results in a dielectric behavior traversing the relaxation phase ( $γ \sim 1.84$ $γ \sim 1.84$ ) accompanied by frequency dispersion, which is beneficial to improve ESP. The superior ESP in this work indicates that BCZT–0.12NL ceramics are a promising candidate used in energy storage capacitors.
