The Evolutionary Dynamics of Battery Technology: A Knowledge-Based Assessment from Article Publications
| Resumo: | The energy storage research field has shown increased interest in technologies that can tackle the challenges brought on by lithium-ion batteries. However, there is limited information on what subjects are actually being studied, what publication trends look like and who are the scientific sponsors of those movements. This study relies on bibliometric and text mining approaches to analyze scientific publications on five emergent alternatives to lithium-ion, specifically, redox-flow, lead-acid, solid-state, lithium-sulfur and sodium-ion. The goal is to uncover publication trends between 2000 and 2021, identify what countries, authors and journals are contributing the most to this research, what topics are being investigated and discussed in each technology and to what extent these technologies are interrelated with the circular economy. There was an increase in the scientific outputs of all batteries throughout the time period, with China clearly leading the scene in terms of publication volume. The majority of authors and institutions publishing on redox-flow, solid-state, lithium-sulfur and sodium-ion were associated with Asian countries. On the other hand, lead-acid publications were mainly dominated by authors and affiliations associated with Europe. Most articles were either published on the Journal of Power Sources or on the Journal of Materials Chemistry A. The text mining analysis confirmed that rechargeable batteries have been growing in importance in the energy storage field. Circularity related publications have also increased, with most authors and affiliations being connected to the USA. All batteries, except solid-state, showed evidence of being highly related to circular economy approaches. Intrinsically, this study contributes to a thorough overview of the research framework on these technologies in the last two decades, while also shedding light on opportunities for further investigation, both from a scientific and circular economy standpoint. |
