6 FAQs about [Prospects of lead-free energy storage ceramics]
Which lead-free bulk ceramics are suitable for electrical energy storage applications?
Here, we present an overview on the current state-of-the-art lead-free bulk ceramics for electrical energy storage applications, including SrTiO 3, CaTiO 3, BaTiO 3, (Bi 0.5 Na 0.5)TiO 3, (K 0.5 Na 0.5)NbO 3, BiFeO 3, AgNbO 3 and NaNbO 3 -based ceramics.
Are lead-free dielectric energy-storage ceramics a hot spot?
At present, the application of dielectric energy-storage ceramics is hindered by their low energy density and the fact that most of them contain elemental lead. Therefore, lead-free dielectric energy-storage ceramics with high energy storage density have become a research hot spot.
Are lead-free anti-ferroelectric ceramics suitable for energy storage applications?
At present, the development of lead-free anti-ferroelectric ceramics for energy storage applications is focused on the AgNbO 3 (AN) and NaNbO 3 (NN) systems. The energy storage properties of AN and NN-based lead-free ceramics in representative previous reports are summarized in Table 6.
How stable is energy storage performance for lead-free ceramics?
Despite some attention has been paid to the thermal stability, cycling stability and frequency stability of energy storage performance for lead-free ceramics in recent years, the values of Wrec, cycle numbers and frequency are often less than 5 J cm −3, 10 6, and 1 kHz, respectively.
What are the characteristics of lead-free ceramics?
Grain size engineered lead-free ceramics with both large energy storage density and ultrahigh mechanical properties High-energy storage performance in lead-free (0.8- x )SrTiO 3 -0.2Na 0.5 Bi 0.5 TiO 3 - x BaTiO 3 relaxor ferroelectric ceramics J. Alloy. Compd., 740 ( 2018), pp. 1180 - 1187
Can lead-free ceramics achieve ultrahigh energy storage density 10 J cm 3?
Recently, high Wrec and high η have been reported in some Bi 0.5 Na 0.5 TiO 3 (BNT)-based lead-free ceramics 19, 20, 21. However, the great challenge of realizing ultrahigh energy storage density (Wrec ≥10 J cm −3) with simultaneous ultrahigh efficiency (η ≥ 90%) still exists in lead-free ceramics and has not been overcome.
