Ceramic capacitors have great potential for application in power systems due to their fantastic energy storage performance (ESP) and wide operating temperature range. In this study, the (1 − x)Bi 0.5 Na 0.47 Li 0.03 Sn 0.01 Ti 0.99 O 3 -xKNbO 3 (BNLST-xKN) energy storage ceramics were synthesized through the solid-phase reaction method. The addition of KN disrupts the long-range ferroelectric order of the BNLST ceramic, inducing the emergence of polar nanoregions (PNRs), which enhances the ESP of the ceramics. The BNLST-0.2KN ceramic demonstrates a high recovered energy density (W rec ∼ 3.66 J/cm 3 ) and efficiency (η ∼ 85.8%) under a low electric field of 210 kV/cm. Meantime, it exhibits a large current density (C D ∼ 831.74 A/cm 2 ), high power density (P D ∼ 78.86 MW/cm 3 ), and fast discharge rate (t 0.9 ∼ 0.1 μs), along with good temperature stability and excellent fatigue stability. These properties make the BNLST-0.2KN ceramic a promising candidate for energy storage applications in low electric fields.

Exploring environment-friendly energy storage ceramics simultaneously featuring large recoverable energy storage density (W rec ), high-energy storage efficiency (ƞ), and excellent temperature stability is highly desirable for the application of pulsed power systems. Herein, Nb 2 O 5 was introduced to modify BNBST-based lead-free relaxor ferroelectric ceramics in an effort to enhance the dielectric temperature stability. (Bi 0.5 Na 0.5 ) 0.65 (Ba 0.3 Sr 0.7 ) 0.35 (Ti 0.98 Ce 0.02 )O 3 (BNBSTC) + x wt%Nb 2 O 5 (0 ≤ x ≤ 4) ceramics were prepared by a solid-state reaction method. The phase structure, microstructure, dielectric, and energy storage properties of the ceramics have been systematically studied. It was found that the ε r -T curve was flattened, and the dielectric temperature stability was effectively improved due to the addition of Nb 2 O 5 . A noticeable W rec (1.44 J/cm 3 ) with high η (84.1%) was obtained in BNBSTC + 2 wt%Nb 2 O 5 ceramics at a low electric field of 90 kV/cm, which was mainly due to a refined P-E loop induced by Nb 2 O 5 . In addition to excellent frequency and anti-fatigue cycle stability, this ceramic provides a new solution for designing pulsed power capacitors with high energy density and high temperature stability under low voltage driving conditions.
