definition of lead-free energy storage 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.

What are the different types of lead-free ceramics for energy storage applications?

Obviously, the lead-free ceramics for energy storage applications can be organized into four categories: linear dielectric/paraelectric, ferroelectric, relaxor ferroelectric and anti-ferroelectric, each with different characteristics in P - E loops, as shown in Fig. 5.

Are lead-free ceramic dielectrics suitable for energy storage?

However, the thickness and average grain size of most reported lead-free ceramic dielectrics for energy storage are in the range of 30–200 μm and 1–10 μm, respectively. This may impede the development of electronic devices towards miniaturization with outstanding performance.

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 is a lead-free ceramic?

Among various lead-free materials, including Bi 0.5 Na 0.5 TiO 3 (BNT) 9, BiFeO 3 (BF) 10, and BaTiO 3 (BT) 11, K 0.5 Na 0.5 NbO 3 (KNN)-based ceramics are one of the most extensively studied dielectric for advanced energy storage applications 1, 2, 3, 4, 12.

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.
