摘要：
The dielectric and energy storage properties of Ba0.4Sr0.6TiO3 particles coated by Al2O3 and SiO2 oxide were investigated. Results showed that the dielectric properties and energy storage density were improved apparently. The improvement of the energy storage density can be ascribed to two factors: one was that the breakdown strength was notably improved by the decrease of the porosity and defects; the other was the reduction of the grain size. Furthermore, the optimized composition showed the maximum energy storage density of 5.09 J/cm(3), whereas the energy storage density of uncoated Ba0.4Sr0.6TiO3 was only 0.24 J/cm(3).
