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)Bi0.5Na0.47Li0.03Sn0.01Ti0.99O3-xKNbO3 (BNLST-xKN) ceramics were synthesized through solid-phase reaction method. The addition of KN disrupts long-range ferroelectric order BNLST ceramic, inducing emergence polar nanoregions (PNRs), which enhances ESP ceramics. BNLST-0.2KN ceramic demonstrates a high recovered density (Wrec ∼ 3.66 J/cm3) efficiency (η 85.8%) under low electric field 210 kV/cm. Meantime, it exhibits large current (CD 831.74 A/cm2), (PD 78.86 MW/cm3), fast discharge rate (t0.9 0.1 μs), along with good stability excellent fatigue stability. These properties make promising candidate applications fields.

It is crucial to discover lead-free materials with ultrahigh recoverable energy density ([Formula: see text][Formula: text]) that can be employed in future pulse power capacitors. In this work, a high [Formula: text]of 4.51 J/cm 3 was successfully obtained Nd-doped AgNb[Formula: text]Ta[Formula: text]O antiferroelectric ceramics at an applied electric field of 290 kV/cm. discovered Nd doping paired Nb-site vacancies could stabilize the phase by lowering temperatures M1–M2 and M2–M3 transitions, which leads higher storage efficiency. Furthermore, Ta co-doping will contribute electrical homogeneity low conductivity, resulting large breakdown strengths. Aliovalent Ag-site serves as novel strategy for construction AgNbO -based excellent performance.

BiFeO 3 –BaTiO is a promising lead-free piezoelectric ceramic, exhibiting high Curie temperature and superior electrochemical characteristics. In this work, [Formula: see text]BiFeO –xBaTiO (BF–xBT, text], 0.28, 0.30, 0.32, 0.34, 0.36) ceramics were fabricated using the conventional solid-state reaction method through precise composition control. Multiple characterization techniques, including X-ray powder diffraction (XRD), scanning electron microscope (SEM), electrical property testing systems, applied to systematically examine crystallographic structure, microstructure, as well dielectric, ferroelectric properties of BF–xBT ceramics. The XRD results confirm that all compositions exhibit typical perovskite transitioning from single rhombohedral phase rhombohedral–cubic mixture BT content increases. SEM shows apparent core–shell microstructures in Notably, demonstrated BF–0.30BT ceramic exhibits maximum constant ([Formula: text]) text][Formula: text]pC/N, while BF–0.34BT displays converse text]pm/V, which highlights suitability BF–BT for high-performance applications.
