Abstract
Energy storage technology has been rapidly developed in the past years. To reveal the development trend of energy storage technologies and provide a reference for the research layout and hot topics, this paper analyzes the output trend of global papers in the field of energy storage based on the published papers on energy storage technologies. The number of papers in the field of energy storage has been increasing rapidly since 2006. The number of annual papers published on energy storage technologies in China accounts for 40% of the world in 2021. Several key indicators, including the number of citable items, total citations, average citations, and the number of highly cited papers, are selected to analyze the overall status of scientific research on energy storage technologies in major countries in the world. Finally, high-frequency keywords for highly cited papers in the field of energy storage are selected to construct a knowledge map based on the co-word matrix. The bibliometric analysis shows that energy storage has a very broad development prospect.
