Abstract

Faced with global energy shortages and environmental challenges, supercapacitors have emerged as a sustainable energy storage solution. Achieving high energy density in these devices hinges on innovative design and composition of electrode materials. Polyoxometalates (POMs), with their rich molecular structures and abundant redox-active sites, have drawn significant attention and are progressively recognized as ideal candidates for supercapacitor electrodes. This review systematically examines POM-based materials, emphasizing their unique properties, contributions to device performance, and recent progress. Key advancements in POM composites, crystalline materials, and hybrid systems are analyzed in terms of their impact on critical metrics. The review highlights assembly strategies such as nanostructuring and interfacial engineering to optimize POM integration and enhance electrochemical performance. Additionally, it evaluates emerging trends and current limitations, outlining challenges and future directions for POM-based supercapacitors. By bridging molecular design and device engineering, this work provides a roadmap for advancing next-generation energy storage systems.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
