Thin film dielectrics are the most selected materials for many power electronics owing to their inherent advantages, such as high power density, fast charging-discharging, and long lifetime. Nowadays, additional demands for the film dielectrics are the high performances under harsh operating conditions, e.g. at high temperatures, which is highly favourable to significantly reduce the size and cost of energy devices. Here, we demonstrated that through design and optimization of the film systems with 1 mol% SiO2-doped BaZr0.35Ti0.65O3 layer sandwiched between two undoped BaZr0.35Ti0.65O3 layers, it is capable to concomitantly enhance breakdown strength and electrical polarization of the systems. The optimized sandwich-structure films yield a greatly improved discharged energy densities of similar to 130.1 J/cm(3) with a high charge-discharge efficiency of similar to 73.8% at room temperature, as well as retain an ultrahigh discharged energy densities of similar to 77.8 J/cm(3) in the ultra-wide temperature range from -100 to 200 degrees C. The presented combination of property modulation with structure engineering paves an effective way to meet the increasingly technological challenges and the requirements of modern electrical energy storage applications.
