Regulating energy storage performances of 0.85NaNbO3-0.15Bi(Zn2/3Nb1/3)O3 ceramics using BaTiO3

Recently, NaNbO3-based ceramics with excellent energy storage performances (ESPs) and fast charge discharge characteristics have attracted great attention. In this case, BaTiO3 modified 0.85NaNbO(3)-0.15Bi(Zn2/3Nb1/3)O-3 (0.85NN-0.15BZN-yBT) ceramics were designed and successfully fabricated using solid state synthesis. The discharge storage density of the ceramics increases from 1.22 J/cm(3) at y = 0-1.84 J/cm(3) at y = 8%, which is 1.5 times higher than pure 0.85NN-0.15BZN ceramics. This ceramic reveals excellent temperature stability up to 150 degrees C, good discharge cycling after 10(5) cycles and high discharge speed of 2.0 mu s, broadening the scope of NaNbO3-based ceramics for energy storage applications.
