The enhancement of energy storage performance in high-entropy

In this work, the energy storage of perovskite-type high entropy ceramic (Pb 0.25 Ba 0.25 Ca 0.25 Sr 0.25 )TiO 3 (reviated as PBCST) was investigated. The recoverable energy density of PBCST is 3.55 J/cm 3 with an energy efficiency of 77.1% under an electric field of 300 kV/cm. To further improve the energy storage performance,
