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.

What is the optimal energy storage performance for lead-free ceramics?

Finally, optimal energy storage performance is attained in 0.85Ba (Zr 0·1 Ti 0.9)O 3 -0.15Bi (Zn 2/3 Ta 1/3)O 3 (BZT-0.15BiZnTa), with an ultrahigh η of 97.37% at 440 kV/cm (an advanced level in the lead-free ceramics) and an excellent recoverable energy storage density (Wrec) of 3.74 J/cm 3.

Can lead-free ceramics be used for Advanced pulsed power systems?

This includes exploring the energy storage mechanisms of ceramic dielectrics, examining the typical energy storage systems of lead-free ceramics in recent years, and providing an outlook on the future trends and prospects of lead-free ceramics for advanced pulsed power systems applications. Graphical Abstract

Can lead-free energy storage materials meet practical needs?

Lead-free energy-storage materials are far from being able to meet practical needs. In addition, other than AN-based and NaNbO 3 (NN)-based AFE materials, bismuth (Bi)-based ceramics, such as Na 0.5 Bi 0.5 TiO 3, BiFeO 3 (BF), Bi 0.2 Sr 0.7 TiO 3, etc, have not attracted enough attention and have not been extensively studied.

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.

What are lead-free electronic ceramics?

In the field of dielectric energy storage, lead-free electronic ceramics have become an inevitable trend. Due to the similarity in the properties of Bi 3+ and Pb 2+, the lone pair of electrons in the outermost 6s 2 layer can be hybridized with the 6p vacant orbital or the O 2− orbital to produce high electron polarizability.
