(1) Background: Lithium plays an extremely important role in the national economy. However, the chemical activity of lithium metal leads to many safety problems in the application of lithium technology, which is the bottleneck problem restricting the development of lithium technology. The purpose of this paper is to describe the research status of lithium technology safety issues visually and dynamically, elucidate the pressing issues in this field and reveal future development trends. (2) Methods: In this paper, metrology literature analysis and knowledge graph methods were adopted. With the help of visualization tools, namely, CiteSpace and VOSviewer, literature data exported from the Web of Science were analyzed in a multi-angle and all-round way. (3) Results: The number of papers in the field of lithium technology safety showed an accelerating trend. Close collaboration between authors and institutions. The scope of the research has gradually shifted from the early focus on the medical application of lithium and the resulting safety issues to the health and safety of lithium batteries. (4) Conclusions: Lithium technology safety is a hot topic in the current academic community. Future research trends will continue to focus on the safety problems and solutions of lithium technology, and pay more attention to sustainable development, especially the research on the improvement and optimization of lithium-ion battery performance.

Journal ratings can reflect the quality of a journal and serve as a crucial reference for evaluating scientific research outcomes. To integrate the preferences of journal rating lists proposed by different institutions, some journal evaluation integration methods have been proposed, with the Weighted Average Percentage (WAP) method being a typical representative. However, the WAP method ignores the level interval information in the rating. To address this issue, we propose the Weighted Average Interval Percentile (WAIP) method. This approach introduces information about journal grade intervals and classifies journals by integrating evaluation rules based on upper and lower bounds. In an empirical study of four well-known journals in the field of economic management, the WAIP method demonstrates its effectiveness and wide applicability, enabling more accurate and stable integration of multiple journal ranking lists. This method aims to provide a more objective perspective for journal ratings, thereby enhancing the fairness and efficiency of the evaluation process.
