Abstract

Achieving simultaneous optimization of high energy storage density at high temperature and robust stability in tungsten bronze-based ferroelectrics remains challenging for practical capacitor applications. This study presents significant advancement in Sr₂NaNb₅O₁₅-based tetragonal tungsten bronze (TTB) ceramics through Bi/Fe co-doping strategy. The developed Sr₂Na_(1-x)Bi_(x)Nb_(5-x)Fe_(x)O₁₅ (SNBNF) system demonstrates significantly enhanced energy storage performance via structural modification and relaxor behavior optimization. Remarkably, the 0.15×-SNBNF composition achieves a record recoverable energy density (W_rec) of 5.23 J/cm³ with 85 % efficiency at 400 kV/cm, surpassing previous TTB-based systems and rivalling perovskite counterparts. The material exhibits a notable stability with minimal variations in W_rec (≤6.5 %) across wide frequency (1–500 Hz), temperature (30–150 °C), and fatigue cycling (10⁵ cycles) in ferroelectric testing conditions. Achieving ultrahigh power density (214.3 MW/cm³), current density (2382 A/cm²), and ultrafast discharge (t_0.9 = 30 ns) together in single compound represents promising candidate in lead-free ceramics for advanced high temperature energy storage applications.
