Abstract
A ferroelectric-piezoelectric ceramic energy storage material and a hybrid process preparation method and use thereof are provided. The ferroelectric-piezoelectric ceramic energy storage material is prepared with micro-nano composite structured particles formed by uniformly mixing polycrystalline powder with sol followed by heat-treatment, the micro-nano composite structured particles including the polycrystalline powder and a nanoscale PLZS component layer distributed around the polycrystalline powder. The method includes preparing sol and polycrystalline powder; performing heat-treatment on the sol and the polycrystalline powder to obtain micro-nano composite structured particles; and obtaining a ferroelectric-piezoelectric ceramic energy storage material sample through a casting process and sintering. By mixing with sol components, the specific surface area and oxygen vacancy content are increased, which is beneficial for reducing the sintering temperature of ceramic materials and improving their dielectric energy storage performance.
