In-depth analysis on thermal hazards related research trends about lithium-ion batteries: A bibliometric study

摘要

Lithium ion batteries (LIBs) play an ever-increasing role in our daily life due to their excellent energy storage performance. However, the thermal hazards of LIBs, occasionally accompanied with fires or explosions, are also severe and worrying issues, which have been concerned by numerous scholars for decades. This paper aims to perform a macroscopic bibliometric reivew on publications related to the thermal hazards of LIBs to date. A total of 826 relevant publications are retrieved from the Web of Science Core Collection database in the period of 1996-2019. A bibliometric study of research on thermal hazards of LIBs is conducted by means of visualization software VOSviewer and CiteSpace. The results are analyzed from the perspectives of the annual publications, countries, institutions, authors, terms, and references. As a result, the analysis presents networks of geographical and institutional cooperation, co-authorship, terms co-occurrence, and co-cited references, as well as corresponding clusters, indicating their contributions to the publications on thermal hazards of LIBs. The results provide a comprehensive overview on the evolution of research hotspots in this domain and can help those researchers who are willing to engage in this research field to quickly understand the research frontier and overall situation.
