Abstract

Developing lead-free film dielectric capacitors with high-performance of energy storage density, efficiency, fatigue endurance, and thermal stabilities is desirable. Here, we report energy storage properties in (1-x)BaTiO₃-xBi_3.25La_0.75Ti₃O₁₂ thin films. It is revealed that a 0.6BaTiO₃-0.4Bi_3.25La_0.75Ti₃O₁₂ thin film with a thickness of 280 nm and a crystallization temperature of 650 °C shows a breakdown strength of 3.23 MV/cm with a large polarization value and dielectric constant. An ultrahigh energy storage density of 61.1 J/cm³ and an efficiency of 84.2% are simultaneously achieved at room temperature. Additionally, excellent fatigue endurance after 6 × 10⁹ cycles and good thermal stability up to 150 °C are observed, implying excellent energy storage performance in 0.6BaTiO₃-0.4Bi_3.25La_0.75Ti₃O₁₂ thin films.
