Nanoscale　microstructure　designing　is　playing　an　important　role　in　improving　the　performance　of　electrode　materials　of　an　electrochemical　battery.　The　Sn　based　anode　is　among　the　very　high-capacity　but　less-stable　materials,　and　has　been　used　mostly　for　anode　of　the　Li-ion　battery　with　unsatisfactory　performance.　In　this　work,　we　design　a　new　type　of　3D　porous　graphene　and　nano-Sn　composite　(Sn/　Void@G)　by　simple　one-step　annealing　of　graphene　oxide,　polystyrene　spheres　and　stannic　chloride　for　both　high　performance　Li-　and　Na-ion　battery　anodes.　More　importantly,　the　3D　porous　graphene　formed　tunable　micro-nano　void　as　a　highly　efficient　＂bumper＂　to　accommodate　the　large　volume　expansion　of　nano-Sn　particles.　As　results,　the　discharge　specific　capacity　of　the　Sn/Void@G,　anode　still　remains　45.3%　while　the　charge-discharge　current　is　increased　50　times,　and　the　capacity　is　more　than　400　mAh　g(-1)　after　500　cycles　at　5C　rate.　For　Na　storage,　the　integrated　anodes　deliver　the　Na　storage　capacity　of　786.1　mAh/g　at　0.1C　rate　and　the　capacity　of　more　than　340　mAh/g　after　800　cycles　at　2C　rate.　The　present　result　on　Li　and　Na　ion　battery　may　pave　the　way　to　next　generation　high　power　and　energy　density　batteries.　(C)　2019　Elsevier　B.V.　All　rights　reserved.
