Dielectric materials for energy storage applications
Submission status
Open
Submission deadline
Searching appropriate material systems for energy storage applications is crucial for advanced electronics. Dielectric materials, including ferroelectrics, anti-ferroelectrics, and relaxors, have emerged as promising candidates. This Collection brings together articles discussing different dielectrics, including polymers, nanocomposites, bulk ceramics, and thin films, for energy storage applications.
All participating journals invite submissions of original research, with Nature Communications and Communications Materials also considering Reviews and Perspectives which fall within the scope of the Collection. All submissions will be subject to the same peer review process and editorial standards as other articles submitted to the participating journals. As the participating journals remain editorially distinct and independent, each journal will come entirely to its own editorial judgement.
The tetragonal tungsten bronzes are promising for high-temperature energy storage applications but the mechanisms for their broad dielectric responses are unclear. Here, a comprehensive experimental and theoretical study of Sr2NaNb5O15 explains its two large dielectric anomalies in terms of structural transitions.
Borophene has unusual anisotropic characteristics which give it potential use in piezoelectric applications. Here, we synthesized few layered borophene and explored their properties in piezoelectric nanogenerator devices.
Polymer dielectrics face huge challenges in the harsh environments of emergent applications. Now, increased energy storage of polymer dielectrics at temperatures up to 250 °C by designing tailored combinations of structural units is reported.
Dielectric ceramics are widely used in advanced high/pulsed power capacitors. Here, the authors propose a high-entropy strategy to design “local polymorphic distortion” in lead-free ceramics, achieving high energy storage performance.
Polymer-matrix composites have a number of attractive properties for use as dielectrics in electrostatic energy storage devices. Here, a BaTiO3 sponge filled with epoxy achieves a high dielectric constant and energy density, attributed to large local electrical displacements.
