| 英文摘要 | NaNbO3 (NN) is generally considered as one of the most promising lead-free antiferroelectric (AFE) perovskite materials with the advantages of low cost, low density and nontoxicity. However, the metastable ferroelectric phase causes a large remanent polarization (P-r) at room temperature, seriously hindering the achievement of excellent energy storage properties. Although via the strategy of lowering the radius of B-site ions and polarizability, a number of AFE NaNbO3-based solid solutions with double polarization-electric field loops are successfully constructed, the hysteresis losses are still too large and the P-r value cannot be reduced to near zero. In this study, Bi(Mg2/3Nb1/3)NbO3 (BMN) was chosen to partially substitute the pure NaNbO3 with the intention of enhancing antiferroelectricity and constructing a local random field simultaneously. These short-range interactions effectively suppress the hysteresis loss and P-r, and slim hysteresis loops were observed in the NN-BMN ceramics. A high charged energy density (3.4 J cm(-3)) and recoverable energy storage density (2.8 J cm(-3)) with high efficiency (82%) were achieved under 300 kV cm(-1) for NN-0.10BMN. Superior stabilities and underdamped discharge abilities were also achieved for NN-0.15BMN with a slightly smaller recoverable energy storage density (2.4 J cm(-3)) but even higher efficiency (90%). The results reported here demonstrate great potential of the designed NN-BMN ceramics for high-temperature capacitors. |
