Analysis of the key materials employed in solid-state lithium batteries based on patent data mining
The development of key materials for solid-state lithium batteries,which represent next-generation high-performance energy storage solutions,is essential for enhancing their energy density,stability,and safety.Considering global patents on solid-state lithium batteries as research objects,this study employs a text mining method to extract material information from these patents.Furthermore,by constructing the primary distribution and co-occurrence network of materials,it analyzes the characteristics of material distribution and identifies potential future materials of solid-state lithium batteries.In addition to the above network,a distribution and co-occurrence network of institutions and materials is also established to examine the material layouts and research considerations of major institutions.Specifically,new materials and research institutions appearing in the patents on solid-state lithium batteries since 2021 are reviewed,and current research hotspots and future development trends are identified.Notably,the review identifies lithium,aluminum,lanthanum,phosphorus,and sulfide as critical materials appearing in the solid-state lithium battery patents.Furthermore,the results reveal that most organizations focus on these core materials,adopting similar strategies for material development and application.Interestingly,a few important institutions also report the development of new materials for solid-state lithium batteries and acquire related patents,thus driving material development,technological innovation,and the commercialization of solid-state lithium batteries.Thus,this paper proposes a new method for analyzing and identifying materials used in solid-state lithium batteries,offering valuable insights for material development and technological innovations within this field.
