- Abstract
(NaBi)TiO lead-free thick films were successfully fabricated on alumina substrates via a screen printing method with 0-10 wt% BaO-BO-SiO glass addition. Microstructure, dielectric properties and energy-storage performance of the thick films were systematically investigated. The results show that the denser thick films were obtained by addition of glass. Thus, the breakdown strength, the energy-storage density and efficiency were greatly improved. The maximum recoverable energy-storage density and efficiency of sample with 1 wt% glass were 2.0 J/cm and 44.1 %, respectively. Meanwhile, a low leakage current density of about 10 A/cm was obtained for all samples at 100 kV/cm.
