Polycrystalline lead-free Ba_0.85Ca_0.15Zr_0.10Ti_0.90O₃ (BCZT), BaTi_0.89Sn_0.11O₃ (BTSn) and 0.4Ba_0.85Ca_0.15Zr_0.10Ti_0.90O₃–0.6BaTi_0.89Sn_0.11O₃ (0.4BCZT–0.6BTSn) ferroelectric ceramics were prepared via sol-gel process and their structural, dielectric and energy storage properties were studied. Pure perovskite structure was confirmed by X-ray diffraction analysis. The evolution of energy storage performances with temperature was studied. A Significant recoverable energy-storage density of 137.86 mJ/cm³ and high energy-storage efficiency of 86.19% under a moderate electric field of 30 kV/cm were achieved in the composite 0.4BCZT–0.6BTSn ceramic at 353 K. Moreover, excellent temperature stability (70–130 °C) of the energy storage efficiency (less than 3%) was achieved.
