Energy storage technology determines the safety, stability, and economic viability of renewable energy utilization. The utilization of carbon materials derived from biomass in energy storage batteries has garnered significant interest owing to its exceptional performance and eco-friendliness. The central research emphasis lies in the regulation of electrochemical characteristics by manipulating pores, structure, and elemental composition. In this study, a comprehensive bibliometric analysis was conducted on 500 pertinent papers obtained from the Web of Science database spanning the years 2013 to 2023. The analysis aimed to examine research trends and the developmental trajectory of biocarbon as an electrode material. This was achieved by employing the latest dataset, keyword clustering, burst analysis, and literature visualization techniques using CiteSpace in conjunction with SATI tools. The analysis identified the most influential countries, institutions, and subject areas in this research field, and listed the top ten papers. The United States and Indonesia are noteworthy contributors to the research findings in this particular field, where the Chinese Academy of Sciences stood out for its high number of publications and citations. Research in this field has predominantly concentrated on supercapacitor preparation and biomass charcoal application. However, there has been a recent shift towards utilizing "waste biomass" in research endeavors.
