摘要
介电电容器与电池等储能器件相比具有功率密度高、充放电速度快等优点,在储能领域受到了广泛关注,但其缺点是储能密度较低。反铁电体由于具有双电滞回线,剩余极化强度接近于0的特征,有望获得高储能密度,是储能材料的优秀候选者。该文首先介绍了反铁电体定义、储能原理以及反铁电体作为储能材料的优势,随后系统综述了目前主流的几种反铁电材料体系包括PbZrO3基、AgNbO3基、NaNbO3基和(Bi0.5Na0.5)TiO3基反铁电陶瓷在储能领域的研究进展,之后对影响储能性能的反铁电陶瓷疲劳性能的研究进展进行了概述,最后对反铁电储能材料的后续研究方向进行了展望。
Dielectric capacitors have been widely concerned in the field of energy storage.Comparing with batteries and other energy storage devices,dielectric capacitors have the advantages of high power density,fast charging and discharging speed and so on.But their disadvantage is the relative low energy storage density.Anti-ferroelectrics is an excellent candidate material for energy storage because it has double hysteresis loop and the residual polarization strength is close to zero,which is beneficial for obtaining high energy storage density.In this review,the definition of anti-ferroelectrics and the advantage of anti-ferroelectric materials as the energy storage materials are introduced firstly.Then,the research progress of anti-ferroelectric materials in energy storage field,including PbZrO3-based,AgNbO3-based,NaNbO3-based and(Bi0.5Na0.5)TiO3-based,is summarized.The research progress of the fatigue property,which is very important in practical application,is also reviewed.Finally,the research prospect of anti-ferroelectrics in energy storage field is proposed.
