The Network Structure of International Research Collaboration in Secondary Batteries

The secondary battery market continues to grow, driven by the increasing demand for sustainable energy storage solutions. However, recent international environmental changes have increased technological protectionism for this key technology. This policy shift will require closer cooperation among allies. This study examined the structure and changes in international research collaboration in secondary batteries. Utilizing the Web of Science database, we applied scientometric analysis techniques to publication data and co-authorship networks. In particular, we identified the structure of the network and key patterns and trends over the last decade to identify dynamic changes. The proportion of collaborative research in secondary battery research papers has steadily increased. Our key findings show that international collaboration in secondary battery research is increasing and that China's influence continues to grow. In particular, the secondary battery international research collaboration network is path-dependent on previously established networks. This path-dependence should be considered for strategic alliances and joint international research in secondary battery research. These findings provide valuable insights into the dynamics of collaboration and can inform policy efforts to promote international collaboration in secondary batteries.
