Supercapacitors have gained significant attention in recent years for their high energy storage efficiency, reliable stability, and eco-friendly process. This study reviews the recent progress in the development of high-performance all-solid-state flexible supercapacitors, focusing on the electrodes and electrolytes used. The operational principles of various supercapacitors are introduced, along with an overview of electrode materials and polymer-based solid-state electrolytes in different systems. The recent advancements and future research directions for all-solid-state flexible supercapacitors are summarized.
In the past few years, supercapacitors (SCs) have attracted great attention in both academic and industrial sectors due to their high energy storage efficiency, reliable stability, and eco-friendly process. Flexible solid-state SCs as one of the ongoing focuses for the development of wearable and portable electronics have become the most promising energy storage devices for the smart power system due to their high power density, fast electrochemical response, high efficiency on the charge-discharge process, and excellent electrochemical stability. In this study, the recent progress in the electrodes and electrolytes used for approaching high-performance of the all-solid-state flexible SCs is reviewed. We first introduce basic operational principles of various SCs. And then we overview the electrode materials including carbon materials, conducting polymers, transition metal oxides/chalcogenides/nitrides, MXenes, metal-organic frameworks, covalent-organic frameworks, and the polymer-based solid-state electrolytes in different systems. Afterward, we summarize recent progress in the development of the all-solid-state flexible SCs and outlook for future research directions.
