| contents | Based on the traditional polycrystalline ferroelectric Ba0.85Ca0.15Zr0.10Ti0.90O3, the 0.4 Ba0.85Ca0.15Zr0.10Ti0.90O3 0.6 Ba0.9Sr0.1Ti0.9Sn0.1O3 medium entropy material with good energy storage and electrocaloric effect performances is designed and synthesized by the solgel method. The structural, dielectric, energy storage and electrocaloric effect properties of the prepared sample were studied. The findings demonstrate that the 0.4 Ba0.85Ca0.15Zr0.10Ti0.90O3 0.6 Ba0.9Sr0.1Ti0.9Sn0.1O3 ceramic simultaneously has a significant recoverable energy storage density of 255.4 mJ/cm3, an efficiency of 67.9%, a large ECE temperature change of 1.36 K, and a high ECE responsivity of 0.453 K.mm/kV under a low electric field of 30 kV/cm. Moreover, excellent temperature stability of Wrec (less than 10%) was achieved in the investigated sample 0.4BCZT 0.6BSTSn. |
