PbZrO₃‐Based Anti‐Ferroelectric Thin Films for High‐Performance Energy Storage: A Review

Abstract

Energy storage capacitors occupy a large proportion in the pulse power equipment, and they play an important role nowadays. In recent years, anti‐ferroelectric materials have attracted increasing attention of researchers due to their high energy storage density. Compared with the lead‐free anti‐ferroelectric materials, PbZrO3 (PZ)‐based anti‐ferroelectric films are defined as promising electrical energy storage devices for pulsed power systems due to their ultrahigh energy storage density. During the past decade, numerous studies have been reported to develop high‐performance PZ‐based anti‐ferroelectric thin films for electrical energy storage applications. This review focuses on the recent progress of PZ‐based anti‐ferroelectric films for energy storage, and provides various ways, such as element modification (replacing of one element in the ABO3 structure by another element), composite materials (adding secondary phase into PZ films to form composite films), and process improvement (such as the tuning of different bottom electrodes), to improve their energy storage density. Finally, the problems and future development directions of the PZ‐based films are raised.

High energy storage of PbZrO3 antiferroelectric thin films via constructing phase composition

“…Lead zirconate is a typical antiferroelectric material, W rec of PZ thin films can possibly reach 50 J cm −3 in the process of phase switching [13]. Compared with other antiferroelectric materials, it has superior E BDS and fatigue resistance, and has more promising application prospects [14][15][16][17][18]. Additionally, there are methods to enhance the electrical properties of thin films by means of calculations and doping [19][20][21].…”

Improved energy storage properties through multilayer stacking of relaxor ferroelectric and antiferroelectric thin films

“…• It aids in improving the energy storage performance [49], by modifying the P-E double hysteresis loop [52,53], that results in enhanced P max [49,54,55], and BDS values [56].…”

Achieving high overall energy storage performance of KNN-based transparent ceramics by ingenious multiscale designing

“…Despite their faster charge–discharge speed over the other three most commonly used battery systems, which are Li-ion batteries, fuel cells, and super-capacitors, energy storage capacitors have been suffering from the drawback of short battery life for quite a long time, 1–6 and their development was thus limited. Such a problem is mainly due to the paradox of obtaining large polarization and high electric breakdown strength simultaneously, which have already been reported in many previous studies.…”
