Characterization of the scientific output on lithium batteries through SciVal topic analysis

Abstract

Introduction: in the context of the depletion of fossil fuels and the threat of climate change, countries are betting on a change in the energy paradigm, where lithium-ion batteries are at the technological frontier and their production has become widespread in recent decades. Objective: to characterize the scientific output on lithium-ion batteries by analyzing SciVal topics. Method: bibliometric study on the scientific output published in Scopus concerning lithium batteries between 2017 and 2021. SciVal was used to analyze articles clustered in the topic "Lithium-ion Batteries; Lithium Ion; Electrodes". Production, citation and collaboration indicators were determined. Result: 98 articles were published in this topic, where the most productive year in papers and citations was 2017 (%Ndoc=25,51 %; %Ncit=46,53). 65,3 % of the articles were registered in the area "Materials Science" and 51 % within the area "Chemistry". 2 % of the articles were found in the top 1 % of the most cited articles, 27,5 % presented international collaboration. China (Ndoc=64), Japan (Ndoc=)20 and the United States (Ndoc=8) concentrated most of the scientific output, with China Three Gorges University being the most productive institution (Ndoc=11). Conclusions: the scientific output on lithium batteries was mainly concentrated in first quartile journals, with articles in the areas of materials science and chemistry. There was a high rate of international collaboration, however, a low University - Company collaboration.
