N2 - (1-x)BiTi0.5Zn0.5O3-x(0.935Bi0.5Na0.5TiO3-0.065BaTiO3) (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 BiTi0.5Zn0.5O3 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.
