Recent progress of ecofriendly perovskite-type dielectric ceramics for energy storage applications

Abstract

Increasing concern has been focused on the search for ecofriendly dielectric ceramics to meet the extensive demands of pulsed capacitors. Due to the advantages of high-energy storage density, efficiency, and excellent temperature stability, optimization of energy storage performance in dielectric ceramics has been a goal in the past decades. This review summarizes the recently reported progress in energy storage properties of typical perovskite-type lead-free ceramics. The advantages and shortcomings in the various kinds of ceramics are discussed. Finally, future prospects are presented to provide some guidelines for the exploration of new materials.

Dielectric films for high performance capacitive energy storage: multiscale engineering

“…), 39 composition (lead-based, lead-free, bismuthbased, etc.) 40 and classification of dielectric type (linear, paraelectric, ferroelectric, relaxor, antiferroelectric, etc. ), [41][42][43] this field has seen many new remarkable advances, especially in dielectric films.…”

Enhanced energy storage performance and thermal stability in relaxor ferroelectric (1‐x)BiFeO3‐x(0.85BaTiO3‐0.15Bi(Sn0.5Zn0.5)O3) ceramics

“…It is known that the energy storage density is closely related to the electrical breakdown strength or threshold (E b ) that determines the operative electric field. Generally, E b is evaluated by the Weibull distribution function, 15,16 described by: X i = lnE bi and Y i = ln(−ln(1 − i/(n + 1))), where X i and Y i are the two parameters in the Weibull distribution, i is the serial number of specimens, E bi is the breakdown electric field of sample with serial number i, and n is the total number of specimens. Figure 4 shows the Weibull distribution plots of the as-prepared samples.…”

“…In response to the promotion of environmental protection, demand for environment friendly dielectric capacitors for energy storage is increasing. Lead‐free dielectrics such as BaTiO 3 , (Bi,Na)TiO 3 , (K,Na)NbO 3 , and BiFeO 3 (BF)‐based systems have thus been extensively investigated 16‐24 . Among these perovskite oxide dielectrics, BF has been considered as a very promising alternative to replace lead‐free materials, due to its super large ferroelectric polarization (≈90 μC/cm 2 ) 25 .…”

“…11 However, probing their intrinsic and extrinsic electric properties is critical to assess their possible role in new types of nanoscale devices, such as nanosensors. 12,13 To date, most efforts have focused on electrical transport in carbon nanotubes, metal and semiconductor nanowires, etc. [14][15][16][17][18] However, few works of electrical transport were concerned with 1D ferroelectric nanostructures.…”
