“…For instance, composite ceramics were reported by mixing dielectric La(Co0.5Ti0.5)O3-8 with a low loss and the oxide conductor (La0.5Sr0.5)CoO3-8. [205] A sudden increase in relative permittivity is found when the volume concentration of (La0.5Sr0.5)CoO3-8 was close to the fc of approximately 0.1 due to the strong interfacial polarization existing at the interfaces between both phases.…”

Ever since the beginning of this century, many kinds of materials have been reported to demonstrate colossal permittivity (CP) or colossal dielectric constant exceeding 10 3 . Accordingly, such CP materials and their further modification and improvement to achieve enhanced CP performance for promising applications in modern electronics, sensors, energy storage, and multifunctional devices and so on have attracted extensive attention. In this review, 2 a general overview of the recent advances in CP materials is provided, ranging from their various categories, physical mechanisms, and modulation methods to promising applications.First, various classes of CP materials are categorized in terms of their structures and dielectric properties. Subsequently, this review provides an insight into the CP mechanisms in views of barrier layer capacitance, defect-dipole cluster and polaronic effect. Moreover, the strategies and prototypical works are introduced in some aspects, including the manipulation of CP properties by doping, percolative capacitors and the methods employed to enhance the dielectric behaviors in CP materials with different forms. We then discuss a wide range of applications based on CP materials, such as modern electronics and energy storage. Finally, the challenges and opportunities for further investigation of CP materials are highlighted in the summary and future perspectives.
