Lithium-ion Battery: Evolution of Available Scientific Publications and Future Research Trends

Abstract

Climate changes awareness has gained more visibility over the past years and new ways of dealing with them are on demand. Lithium-ion battery research is one of contributors to this technological innovation to overcome carbon-based source of energy, due to their excellent performance and long cycle life. This paper aims to apply a bibliometrics analysis to track the existing scientific publications on lithiumion battery research without timespan restrictions. From Web of Science (WoS) a total of 65154 publications are retrieved belonging to the refined keywords that are present in publications Title, Abstract and Keywords. In order to analyze the dataset, a bibliometric analysis will be presented regarding the construction of networks based on the keywords co-occurrence, co-authorship, co-cited references and distributions of publications over geographical regions, institutions, scholars, and categories contributions. From this network, an overall view of the output dissemination of scientific publications made about this domain will be developed. A bibliometric analysis on lithium-ion battery is assessed by means of quantitative and visualization tools using R and VOSviewer software. The results obtained are evaluated and summarized from the perspective of total annual publications, countries, institutions, authors, terms, journals and subject categories. This analysis illustrates the role of collaborative partnerships in successful scientific research on lithium-ion battery, with China contributing the most to knowledge production with a total of 33318 publications, 15 of 20 most productive institutes, 12 of 20 most prolific authors and 3 of 10 most cited articles. China and US have the strongest relationship when it comes to collaboratives papers with 3087 co-authorship articles. Tsinghua University in China is the most productive institute with 1393 articles and Nanyang Technology University in Singapore is the most influential institute with 243 citations. Journal of Power and Sources has published the most articles among all the journals, having a total of 6104 publications. The process of analyzing and evaluating scientific production and the results obtained, are expected to contribute to an overview of the trajectory of the research on lithium-ion battery, highlighting main actors leading knowledge production on this domain and assess new trend topics that can help in future research.
