Abstract

Recently, NaNbO₃-based ceramics with excellent energy storage performances (ESPs) and fast charge-discharge characteristics have attracted great attention. In this case, BaTiO₃ modified 0.85NaNbO₃-0.15Bi(Zn_2/3Nb_1/3)O₃ (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/cm³ at y = 0–1.84 J/cm³ 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 ℃, good discharge cycling after 10⁵ cycles and high discharge speed of 2.0 μs, broadening the scope of NaNbO₃-based ceramics for energy storage applications.
