Lithium-ion　batteries　(LIBs)　are　an　essential　part　for　electric　vehicles　(EVs)　and　have　experienced　rapid　growth　with　the　strong　demand　for　EVs.　Concerns　over　the　sustainable　supply　of　EV-LIBs　have　been　voiced,　but　only　a　few　studies　have　investigated　the　international　trade　in　EV-LIBs,　which　has　a　significant　impact　on　EV　production　in　the　complicated　and　volatile　international　trade　environment.　To　fill　this　gap,　this　study　investigates　the　international　EV-LIB　trade　from　a　dynamic　perspective.　First,　the　dynamic　structural　evolution　of　the　EV-LIB　trade　from　2012　to　2019　is　explored　from　three　perspectives,　i.e.,　backbone　structure,　geospatial　characteristics　and　trade　communities,　by　constructing　a　weighted　and　directed　network.　Second,　the　hidden　systemic　risks　in　the　international　EV-LIB　trade　are　revealed　by　the　proposed　trade　network　risk　transmission　(TNRT)　model　in　two　supply　shortage　scenarios.　The　results　show　a　heterogeneous　structure　in　the　backbone　network,　and　the　trade　barycenter　is　transitioning　from　Asia　to　Europe.　In　addition,　a　＂robust-yet-fragile＂　characterization　is　revealed　in　the　global　EV-LIB　trade　network,　and　the　hidden　risks　in　leading　EV-LIB　exporter　nodes　and　trade　edges　are　uncovered.　The　findings　will　support　authorities　seeking　effective　strategies　to　manage　the　EV-LIB　trade　and　build　a　more　resilient　trade　system.
