Superior energy storage performance with a record high breakdown strength in bulk Ba0.85Ca0.15Zr0.1Ti0.9O3-based lead-free ceramics via multiple synergistic strategies

A composition and structure optimization strategy combined with a two-step sintering (TSS) process is proposed to design and fabricate (1− x )Ba 0.85 Ca 0.15 Zr 0.1 Ti 0.9 O 3 − x Bi(Mg 1/2 Sn 1/2 )O 3 (BCZT-BMS x -TSS) lead-free ceramics.
