High-performance BaZr0.35Ti0.65O3 Thin Film Capacitors with Ultrahigh Energy Storage Density and Excellent Thermal Stability

Abstract

The ability of working at ultralow (-90 ̊C) or ultrahigh (200 ̊C) temperature with superior energy storage properties is essential for dielectric capacitor to operate in harsh environment. Here, we realized ultrahigh recoverable energy density (Wrec) (78.7J/cm3) and efficiency (η) (80.5%) in BaZr0.35Ti0.65O3 film capacitors through enhancing breakdown electric field strength at room temperature. Moreover, the BaZr0.35Ti0.65O3 film capacitor exhibit great energy storage properties when measured from -150 ̊C to 200 ̊C. The Wrec and η can reach the value of 41.9 J/cm3 and 66.4% under electric strength of 4.0 MV/cm even at 200 ̊C, respectively. Especially, the variation of both Wrec and η at 200 ̊C during the 1×106 cycles ferroelectric fatigue are less than 3%. All these reveal that The BZT film capacitors are a commendable material for application in the equipment working at harsh environment.
