In　the　rapidly　expanding　global　electric　vehicle　lithium-ion　battery　supply　chain　network　(EV　LIB　SCN),　intricate　intercontinental　and　interrelated　connections　render　it　susceptible　to　geopolitical　disturbances.　The　complex　supplier–buyer　dynamics　within　this　network　facilitate　the　propagation　of　disruptions,　complicating　the　identification　and　evaluation　of　the　consequences　of　geopolitical　disruptions.　Existing　recommendations,　grounded　in　macro-level　material　flow　data,　offer　limited　guidance　for　EV　LIB-associated　enterprises　in　managing　such　disruptions.　To　address　this　gap,　this　study　constructs　a　meso-level　EV　LIB　SCN　incorporating　realistic　supplier–buyer　relationship　data　among　relevant　firms.　A　supply　chain　network　vulnerability　(SCNV)　index　has　been　designed　to　quantify　the　disruption　impact.　Furthermore,　a　geopolitical　disruption　diffusion　(GDD)　model　has　been　developed　to　simulate　the　disruption　propagation　in　two　distinct　scenarios,　i.e.,　single-region　blockade　and　inter-region　blockade.　This　study　broadens　the　scope　of　EV　LIB　SCN　investigations　from　macro-　to　meso-level　analyses,　and　the　evaluation　of　both　direct　and　indirect　impacts　of　geopolitical　disruptions　enhances　comprehension　of　geopolitical　disruption　risks　in　global　supply　chain　networks.　©　2024　Elsevier　Ltd
