Materials exhibiting high energy/power density are currently needed to meet the growing demand of portable electronics, electric vehicles and large-scale energy storage devices. The highest energy densities are achieved for fuel cells, batteries, and supercapacitors, but conventional dielectric capacitors are receiving increased attention for pulsed power applications due to their high power density and their fast charge–discharge speed. The key to high energy density in dielectric capacitors is a large maximum but small remanent (zero in the case of linear dielectrics) polarization and a high electric breakdown strength. Polymer dielectric capacitors offer high power/energy density for applications at room temperature, but above 100 °C they are unreliable and suffer from dielectric breakdown. For high-temperature applications, therefore, dielectric ceramics are the only feasible alternative. Lead-based ceramics such as La-doped lead zirconate titanate exhibit good energy storage properties, but their toxicity raises concern over their use in consumer applications, where capacitors are exclusively lead free. Lead-free compositions with superior power density are thus required. In this paper, we introduce the fundamental principles of energy storage in dielectrics. We discuss key factors to improve energy storage properties such as the control of local structure, phase assemblage, dielectric layer thickness, microstructure, conductivity, and electrical homogeneity through the choice of base systems, dopants, and alloying additions, followed by a comprehensive review of the state-of-the-art. Finally, we comment on the future requirements for new materials in high power/energy density capacitor applications.

“…The two responses are often reported as simply the piezo response, but the observation can be differentiated via the quadratic response to field observed for electrostriction compared to linear dependence of polarization with field for the piezo effect. In relaxor ferroelectrics both physical processes are generally responsible for their actual response [26,30]. The field dependence of the strain response from several of the measured lattice planes (Figure 5) displays a mix of both behaviors and is more complex than the bulk behavior (Figure 3).…”

“…For instance, results from relaxor PMN-PT ceramics and crystals showed that the dielectric and piezoelectric properties were correlated with their domain size [24]. Domain sizes for PIN-PMN-PT single crystals and thin films have been shown to be dependent on large variety of factors and examples ranging from tens to a few hundreds of nm have been recorded [24][25][26][27][28][29], although tens of nm is more typical. 1)] for different lattice planes as a function of temperature and depth from the surface of the sample (∼2 nm) into its bulk.…”

In Situ Electric-Field Study of Surface Effects in Domain Engineered Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 Relaxor Crystals by Grazing Incidence Diffraction

In this work, we present a grazing incidence X-ray diffraction study of the surface of a 0.24Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) [011] poled rhombohedral single crystal. The near surface microstructure (the top several tens to hundreds of unit cells) was measured in situ under an applied electric field. The strains calculated from the change in lattice parameters have been compared to the macroscopic strain measured with a strain gauge affixed to the sample surface. The depth dependence of the electrostrain at the crystal surface was investigated as a function of temperature. The analysis revealed hidden sweet spots featuring unusually high strains that were observed as a function of depth, temperature and orientation of the lattice planes.

“…The local structural heterogeneity can generate interfacial energies that compete with the bulk energies, flattening the free‐energy profile and enhancing ε r and d 33 . Besides, other RE 3+ ‐doped PMN‐PT and PMN‐PT‐based ceramics were also reported, such as La 3+ ‐doped PMN‐PT ceramics, 13 Sm 3+ ‐doped Pb(Sc 1/2 Nb 1/2 )O 3 ‐Pb(Mg 1/3 Nb 2/3 )O 3 ‐PbTiO 3 (PSN‐PMN‐PT) ceramics, 14 and Pr 3+ ‐doped PIN‐PMN‐PT ceramics 15 . The ferroelectric, piezoelectric, and energy storage properties of these systems were well changed by RE 3+ dopants, but their common point is that when the RE 3+ doping concentration exceeds a certain value, an undesirable pyrochlore phase will appear in the phase structure, making these ceramics difficult to achieve the best state 3,9–15 .…”

Undesirable pyrochlore phase often appears in Pb(Mg1/3Nb2/3)O3‐PbTiO3 (PMN‐PT)‐based ceramics with high rare‐earth ion (RE3+) doping concentration, which greatly limits their development. In this study, 0–5 mol% Sm3+‐doped Pb(Mg1/3Nb2/3)O3‐29PbTiO3 (PMN‐29PT:0‐5Sm) ceramics were first synthesized using traditional precursor method. In the X‐ray diffraction spectra and scanning electron microscope images of PMN‐29PT:3‐5Sm ceramics, the diffraction peaks of pyrochlore phase and pyrochlore grains with octahedral morphology were observed, respectively. The reason for the appearance of the pyrochlore phase is that Sm3+ doping causes the Nb‐rich regions. To eliminate the pyrochlore phase, PMN‐29PT:3‐5Sm ceramics were resynthesized by an improved precursor method in which an excess of 4 mol% MgO was added to the reactants before pre‐sintering. After adding an excess of 4 mol% MgO, the concentration ratio of Nb5+ and Mg2+ in the pyrochlore grains returned to the value in the perovskite grains, and the pyrochlore phase was transformed into the perovskite phase PMN. The dielectric, ferroelectric, and electromechanical properties were compared before and after eliminating the pyrochlore phase. The results show that the comprehensive performance of the ceramics is improved after eliminating the pyrochlore phase.
