Abstract
High recoverable energy density (10 J cm−3) multilayers have been fabricated from lead-free 0.61BiFeO3-0.33(Ba0.8Sr0.2)TiO3-0.06La(Mg2/3Nb1/3)O3 ceramics. High breakdown strength > 730 kV cm-1 was achieved through the optimisation of multilayer processing to produce defect-free dielectric layers 7 μm thick. Excellent temperature, frequency, fatigue stability and fast charge-discharge speed were observed in the multilayer, critical for their potential use in power electronics.
