Metal oxide-biochar composites have become a promising class of materials for supercapacitor applications. The incorporation metal oxides into the biochar matrix offers several advantages, including improved capacitance, stability, ion diffusion, and conductivity. synergistic interactions between result in enhanced capacitance stability composites. Biochar's porous nature makes transport easier, which improves energy storage capabilities speeds up charge-discharge rates. Additionally, addition composites' conductivity, facilitating effective electron transport. However, research gaps still remain despite these developments, requiring optimization composition structural features as well their synthesis approaches. Furthermore, order to precisely control characteristics composites, greater comprehension mechanism underlying creation is necessary. This agenda calls new with electrochemical performance using diverse oxide precursors made from various agricultural wastes. article summarizes recent developments waste upcoming supercapacitors. We believe findings, terms fundamentals, development, challenges, future prospects, this review would be beneficial readers will facilitate concerned era.

Carbon materials play a fundamental role in electrochemical energy storage due to their appealing properties, including low cost, high availability, environmental impact, surface functional groups, electrical conductivity, alongside thermal, mechanical, and chemical stability, among other factors. Currently, carbon can be considered the most extensively explored family field of supercapacitors batteries, which are devices covering wide range applications demanding power energy. However, as with all technologies, there is process adaptation optimization; hence, have been aligning advances that emerge. Similarly, over years, new methods processes discovered produce carbons more suitable for storage, adapting them present good synergy metal-based compounds meet current standards. In this work, we compilation used from inception these technologies day.
