Lithium-ion batteries (LIBs) can help support sustainability through electric vehicles and energy storage. There is now wide adoption of LIBS and supply sourcing concerns for LIB metals such as cobalt and lithium. LIB End-of-life (EOL) management is essential for LIB metals supply chain resilience. Safety risks within EOL LIBs are potential disruption concerns. In this study safety risks during LIB EOL stages are explored with a circular economy (CE) perspective. Safety risk sources in EOL LIB management and their effects on activities are quantified and ranked by a combined Best-Worst Method (BWM) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methodology. This methodology combines risk analysis with multi-criteria decision-making (MCDM) to provide initial insights into relative safety risk source improvements. General practical and research implications for future studies about the CE of LIBs emerge from this study's computational and analytical results.

锂离子电池 (LIB) 可以通过电动汽车和储能帮助支持可持续发展。现在广泛采用 LIBS 和 LIB 金属（例如钴和锂）的供应采购问题。LIB 报废 (EOL) 管理对于 LIB 金属供应链的弹性至关重要。EOL LIB 中的安全风险是潜在的中断问题。在本研究中，从循环经济 (CE) 的角度探讨了 LIB EOL 阶段的安全风险。EOL LIB 管理中的安全风险源及其对活动的影响通过最佳-最差方法 (BWM) 和按理想解决方案相似度排序的技术 (TOPSIS) 方法进行量化和排名。该方法将风险分析与多标准决策 (MCDM) 相结合，以提供对相关安全风险源改进的初步见解。
