Abstract
Abstract (1- x )BiTi 0.5 Zn 0.5 O 3 -x(0.935Bi 0.5 Na 0.5 TiO 3 -0.065BaTiO 3 ) (abbreviated as BTZx) lead-free ceramics were prepared by using a conventional solid state reaction method and their composition and temperature dependent energy-storage properties were investigated. The addition of BiTi 0.5 Zn 0.5 O 3 sharply decreased the content of ferroelectric phase, leading to lowered remanent polarization and coercive field. A large energy storage density (W) of 1.04 J cm −3 was achieved at 95 kV cm −1 for BTZ0.916. In the high temperature region, the remanent polarization was suppressed, while maximum polarization still maintained at a high level. Significantly enhanced W of ~0.952 J cm −3 at 80 kV cm −1 was obtained with a relatively high efficiency of ~0.8, making these materials attractive in energy storage applications.
