Recent Advances and Challenges in Hybrid Supercapacitors Based on Metal Oxides and Carbons

Inorganics, Год журнала: 2025, Номер 13(2), С. 49 - 49

Опубликована: Фев. 8, 2025

Hybrid supercapacitors (HSCs) are a novel type of supercapacitor composed battery-type electrodes and capacitor-type electrodes, which have directly transformed the global energy landscape. On one hand, they can replace clean sources that heavily dependent on climatic conditions in specific regions, thereby enhancing effective utilization intermittent sources. other with their high density akin to secondary batteries long lifespan power characteristic supercapacitors, perfectly bridge gap between supercapacitors. This article reviews fundamental storage principles HSCs highlights latest optimization strategies for based transition metal oxides (TMOs) carbon over past two years. These include heteroatom doping, heterostructured materials, nanocomposites, metal–organic frameworks (MOF). Finally, prospects future research directions discussed.
