Selection criteria of polymer nanocomposites for electrical energy storage applications: A concise review

Abstract

Polymer nanocomposites are drawing considerable interest in electrical energy storage research owing to their distinctive characteristics and promising roles in various devices, such as batteries, supercapacitors, and fuel cells. This review examines the selection criteria of polymer nanocomposites for electrical energy storage applications and the current advancements in developing and producing polymer nanocomposites specifically tailored for electrical energy storage applications. Key topics covered include the selection of polymer matrices, choice of nanofillers, fabrication techniques, characterization methods, and performance evaluation of the resulting nanocomposites. The impact of nanofiller dispersion, interface engineering, and morphology control on electrical storage properties is emphasized. Proper dispersion enhances uniformity and interfacial interactions, improving electrical, mechanical, and thermal properties. Interface engineering boosts polymer-nanofiller compatibility, while morphology control optimizes nanofiller structure and arrangement for better storage efficiency. Emerging trends, challenges, and future research directions are also discussed, providing insights for developing advanced polymer nanocomposites with improved electrical energy storage capabilities.
