Only a few review articles address the systematic investigation and development of various reported lead-free ceramics used for energy storage. Discussing and analyzing the most recent progress in developing of different lead-free ceramics holds great significance in advancing pulsed power systems with excellent performance. Fig. 3.
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. Table 6.
To better optimize the energy storage performance of BT-based lead-free ceramics, B. Liu et al. coated BT with Al 2 O 3 and SiO 2 using the chemical coating method and reduced the average grain size below 200 nm. This led to improved breakdown strength (190 kV cm −1) and enhanced energy storage density (0.725 J cm −3). Q.
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).
Recently, a higher recoverable energy density of 1.98 J/cm 3 with an efficiency of 90.57% was obtained in Ba 0.4 Sr 0.6 TiO 3 (BST) lead-free ceramics upon adding 9 wt% Bi 2 O 3 -B 2 O 3 -SiO 2 (BBS) glass. With increasing BBS glass content, the BDS increased clearly (the maximum BDS was 279 kV/cm in the BST-9 wt% BBS ceramic).
Along with the rapid development of electrostatic capacitors requiring dielectric materials to exhibit environmental-friendly and outstanding performance, numerous efforts have been made to enhance the energy storage properties of lead-free ceramics for pulsed power capacitor applications in recent reports , , , .
