AbstractIn this work, (0.93 - x)Bi0.5Na0.5TiO3-0.07BaTiO(3)-xNaNbO(3) (BNT-0.07BT-xNN) lead-free energy storage ceramics were designed on the basis of the phase diagram of this system. The phase structure and energy storage property were studied. The NN substitution into BNT-BT increased the crystal structure symmetry and induced an obvious disruption of the ferroelectric order. At x = 0.20, an extremely slim P-E hysteresis loop along with a large recoverable energy storage density (W-rec) of 2.08 J/cm(3) and a high energy storage effificiency (eta) of 81% was obtained at a moderate electric field of 160 kV/cm. The BNT-BT-0.02NN ceramic possessed a high discharge energy density (W-d similar to 1.44 J/cm(3)) and a fast discharge speed (t(0.9) similar to 153 ns) at an electric field of 160 kV/cm. These results show that the BNT-0.07BT-xNN material may be a promising candidate for capacitors.
