摘要
电介质电容器作为重要的储能形式之一,具有功率密度高、充放电速度快等优点,已被广泛应用于新能源汽车、脉冲功率器件等领域。铌酸银(AgNbO_(3))无铅反铁电材料因具有独特的双电滞回线特性,具有较为优异的储能性能和温度稳定性,是理想的电介质储能材料。综述了近年铌酸银无铅反铁电陶瓷的制备及储能性能改善的研究进展,详细阐述了基于容差因子、离子极化率以及二者协同调控对铌酸银基陶瓷储能性能的影响规律及内在机制,并对其未来的研究方向进行了展望。
As one of the important energy storage devices,dielectric capacitors have been widely used in new energy vehicles,pulse power devices and other fields due to its high-power density and fast charging/discharging rate.With specific double hysteresis loops,silver niobate(AgNbO_(3))lead-free antiferroelectric ceramic is an ideal dielectric energy storage material due to its excellent energy storage performances and temperature stability.As a result,this article reviews the research progress on its preparation methods and its improvement of energy storage performances.The effects of tolerance factor,ionic polarizability and their synergistic regulation on the energy storage performances are illustrated in detail for silver niobate-based ceramics.Moreover,the future development directions are also prospected.
