Abstract: In order to fully understand the dielectric energy storage characteristics and micro defects of ceramic materials, the research methods of dielectric energy storage characteristics and micro defects of ceramics were proposed. Firstly, ceramic sample materials according to the preparation process of ceramic materials are prepared. Secondly, the relationship between relative dielectric constant, dielectric loss and temperature curve is analysed, and the dielectric energy storage characteristics of ceramic materials are analysed. Finally, the micro defects of ceramic materials were characterised at different reaction temperatures and sintering temperatures. The results show that when the temperature is 120°C, the energy storage density of ceramic materials with mole fractions of 5%, 6% and 7% are 1.24 J/cm³, 1.26 J/cm³ and 1.20 J/cm³ respectively, and the energy storage efficiency is 86.99%, 91.399% and 94.08% respectively. At the sintering temperature of 1,250°C, there are basically no obvious micro defects.
