In the context of escalating global energy demands and the push for renewable energy sources, biochar has emerged as a significant topic of interest due to its remarkable catalytic properties and potential applications in electrochemical energy storage devices. A detailed bibliometric study conducted using Citespace software, encompassing 602 publications from the Web of Science database spanning the years 2014 to 2023, has provided a visual and analytical overview of the research landscape surrounding biochar. This analysis has revealed China as a leading country in biochar research, underscoring its scholars’ contributions to the field.

The study employs various bibliometric tools, including visual analysis networks, to map national collaboration, institutional cooperation, and individual author contributions to the field. Further, through journal co-citation and keyword co-occurrence analyses, the study highlights the primary subject areas, core journals, current research hotspots, and emerging frontiers in biochar research. Notably, the application of biochar in electrochemical energy storage devices is identified as a burgeoning area of interest, driven by biochar’s inherent properties such as high carbon content, substantial porosityPorosity of biochar is a key factor in its effectiveness as a soil amendment and its ability to retain water and nutrients. Biochar’s porosity is influenced by feedstock type and pyrolysis temperature, and it plays a crucial role in microbial activity and overall soil health. Biochar More, and chemical and mechanical stability.

The introduction section of the article underscores the urgency of developing renewable energy sources and the role of energy storage devices in meeting the world’s energy needs. It points out the depletion of traditional energy sources and the environmental concerns associated with them, paving the way for the exploration of alternative materials like biochar. Biochar’s utility in converting biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More and solid waste into valuable electrode materials for energy storage devices exemplifies the innovative approach of “turning waste into treasure” and highlights the potential for using agricultural and forestry residues as sources of biochar.

Bibliometrics, as elucidated in the study, serves as a critical tool for analyzing and forecasting trends in research fields. The application of Citespace software in this study has facilitated a comprehensive understanding of the development narrative, research hotspots, and trends in the use of biochar within the realm of electrochemical energy storage.
