Electrical energy storage systems (EESSs) with high energy density and power density are essential for the effective miniaturization of future electronic devices. Among different EESSs available in the market, dielectric capacitors relying on swift electronic and ionic polarization-based mechanisms to store and deliver energy already demonstrate high power densities. However, different intrinsic and extrinsic contributions to energy dissipations prevent ceramic-based dielectric capacitors from reaching high recoverable energy density levels. Interestingly, relaxor ferroelectric-based dielectric capacitors, because of their low remnant polarization, show relatively high energy density and thus display great potential for applications requiring high energy density properties. In this study, some of the main strategies to improve the energy density properties of perovskite lead-free relaxor systems are reviewed, including (i) chemical modification at different crystallographic sites, (ii) chemical additives that do not target lattice sites, and (iii) novel processing approaches dedicated to bulk ceramics, thick and thin films, respectively. Recent advancements are summarized concerning the search for relaxor materials with superior energy density properties and the appropriate choice of both composition and processing routes to match various applications’ needs. Finally, future trends in computationally-aided materials design are presented.

Abstract The intricacies in identifying the appropriate material system for energy storage applications have been the biggest struggle of the scientific community. Countless contributions by researchers worldwide have now helped us identify the possible snags and limitations associated with each material/method. This review intends to briefly discuss state of the art in energy storage applications of dielectric materials such as linear dielectrics, ferroelectrics, anti-ferroelectrics, and relaxor ferroelectrics. Based on the recent studies, we find that the eco-friendly lead-free dielectrics, which have been marked as inadequate to compete with lead-based systems, are excellent for energy applications. Moreover, some promising strategies to improve the functional properties of dielectric materials are discussed.
