Two-dimensional　(2D)　nanostructure　is　currently　the　subject　in　the　fields　of　new　energy　storage　and　devices.　During　the　past　years,　a　broad　range　of　2D　materials　represented　by　graphene　have　been　developed　and　endow　with　excellent　electrochemical　properties.　Among　them,　elemental　2D　materials　(Xenes)　are　an　emerged　material　family　for　Li/Na-ion　battery　(LIB/SIB)　anodes.　Compared　with　other　2D　materials　and　bulk　materials,　Xenes　may　exhibit　some　great　superiorities　for　Li/Na　storage,　including　excellent　conductivity,　fast　ion　diffusion　and　large　active　sites　exposure.　In　this　review,　we　provide　a　systematic　summary　of　the　recent　progress　and　achievements　of　Xenes　as　well　as　their　applications　in　LIBs/SIBs.　The　broad　categorization　of　Xenes　from　group　IIIA　to　VIA　has　been　concisely　outlined,　and　the　related　details　in　syntheses,　structures　and　Li/Na-ion　storage　properties　are　reviewed.　Further,　the　latest　research　progress　of　Xenes　in　Li/Na　ion　batteries　are　summarized,　together　with　mechanism　discussions.　Finally,　the　challenges　and　prospects　of　Xenes　applied　to　Li/Na　ion　battery　are　proposed　based　on　its　current　developments.
