Multiscale microstructure design for high-performance dielectric energy storage materials

Dielectric materials are increasingly recognized as promising candidates for advanced energy storage and power amplification, particularly in dielectric capacitors that combine high power density with rapid charge-discharge capability and exceptional cycling stability. Special attention is given to the development of multilayer ceramic capacitors (MLCCs) for high-power pulsed systems, where the challenge lies in simultaneously achieving miniaturization and high energy density. This review highlights recent advances in dielectric materials, with particular emphasis on polarization engineering strategies that enhance energy and power densities through multiscale microstructural design, spanning devices,…
