Research progress and future trend of retired power battery recycling: CiteSpace-based visual analysis

Based on CNKI and WoS databases, the publishing trend, high-yield authors, high-yield institutions, keyword co-occurrence and clustering of research on retired power battery recycling during 2000-2023 were analyzed using the bibliometrics software CiteSpace. The results show that the study on retired power battery recycling has shown a continuous upward trend since 2000. The foreign high-prolific authors gather and cooperate tightly, while domestic high-prolific authors are scattered and have weak cooperative relations. Foreign high-yield institutions are concentrated in developed countries, and domestic high-yield institutions are mostly from cities with higher economic development levels. The keywords co-occurrence and clustering analysis show that the recycling process, echelon utilization and the recycling system construction of retired power batteries are the research focus. In the future, cross-regional, cross-industry and interdisciplinary cooperation should be positively developed. The research on the construction of the efficient, intelligent and safe retired power battery recycling system and echelon utilization industrial chain should be strengthened to promote the healthy development of the new energy vehicle industry chain.
