The authors declare no conflict of interest. The data that support the findings of this study are available from the corresponding author upon reasonable request.

Why do we need lead-free ceramics?

Learn more. Owing to the current global scenario of environmental pollution and the energy crisis, the development of new dielectrics using lead-free ceramics for application in advanced electronic and energy storage systems is essential because of the high power density and excellent stability of such ceramics.

What is a lead-free dielectric ceramic?

State-of-the-art lead-free dielectric ceramics (bulk ceramics, multilayer ceramic capacitors, and ceramic thin films) are discussed along with how energy storage performance may be normalised to take into account the effect of thickness and electrode area. 3.1.

How to optimize energy storage performance of nn-based lead-free ceramics?

The ceramics exhibit well-defined double P - E loops and reduced Pr. M. Zhang et al. proposed a strategy by adjusting the local structure and defect chemistry with SrSnO 3 and MnO 2 to optimize the energy storage performance of NN-based lead-free ceramics from anti-ferroelectric to relaxor states, as shown in Fig. 26 (e).

What are the energy storage performance metrics of lead-free bulk ceramics?

The energy storage performance metrics (Emax, ΔP, Wrec and η) of lead-free bulk ceramics are summarised and depicted in Fig. 17. Wrecvs. η (Fig. 17a) NN and NBT-based bulk ceramics currently demonstrate superior performance, exhibiting Wrec > 8 J cm−3 and η > 80%. AN-based bulk ceramics present lower Wrec (< 8 J cm−3) and lower η (< 80%).
