Abstract

Ceramics with superior energy storage properties, serving as the dielectric layer of capacitors, are crucial for constructing high performance capacitors. In this study, we designed and characterized (1-x) (0.94Bi_0.5Na_0.5Ti0₃-0.06BaTiO₃)-xNaTaO₃ (BNBT-xNT) lead-free ceramics with enhanced energy storage capabilities. The incorporation of NaTaO₃ induced a transition from non-polar to polar relaxation phase and transformed nano-domains into nano-micro domains. Under an applied electric field of 250 kV/cm, the 0.92 BNBT-0.08NT ceramics exhibited significantly higher effective energy storage density W_rec (3.07 J/cm³) and energy storage efficiency η (68 %). Moreover, these ceramics demonstrated remarkable discharge energy density W_d (1.1 J/cm³), high power density P_D (75 MW/cm³), and fast charge and discharge speed t_0.9 (258 ns). The exceptional stability in terms of energy storage performance suggests that BNBT-0.08NT ceramics hold great potential for pulse power applications.
