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.
