Boosting energy storage performance of BiFeO₃-based multilayer capacitors <i>via</i> enhancing ionic bonding and relaxor behavior

Abstract

F-BT- x NT MLCCs were designed and expected to achieve high energy-storage density because of ultrahigh P s value of BiFeO 3 system. With enhancement of ionic bonding and dielectric relaxation, excellen U rec = 9.1 J cm −3 and η &gt; 80% were achieved at x = 0.12.
