| contents | Ba0.85Ca0.15Zr0.1Ti0.9O3/La0.8Sr0.2MnO3/Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT/LSMO/BCZT) sandwich films were elaborated using the sol-gel spin coating process. The dielectric properties displayed excellent thermal stability with the temperature coefficient of capacitance, TCC, remaining within 10% between -50 C and 300 C. The high energy storage density, Wrec, of 11.8 J/cm3 observed in this sandwich films, is nearly twice as high as that of the BCZT films, with an efficiency, n, of 77% under a weak electric field of 800 kV/cm. Furthermore, the stability of Wrec and n was observed along the studied temperature interval making them promising candidates for high-temperature energy storage capacitors. |
