In　this　study,　multi-walled　carbon　nanotubes/Cu　nanowires-coated　on　the　copper　foil　used　as　a　three-dimensional　porous　current　collector　for　Si　electrode　has　been　developed　to　tackle　the　problems　of　silicon-based　lithium-ion　batteries.　The　highly　conductive　Cu　nanowires　cooperated　with　robust　multi-walled　carbon　nanotubes　not　only　improve　the　inferior　electric　conductivity　of　the　Si　anode　but　also　strengthen　the　total　frame　stability.　Furthermore,　the　three-dimensional　structure　creates　numerous　voids　on　the　surface　of　Cu　foils.　Such　porous　structure　of　the　modified　current　collector　offers　the　flexible　volume　expansion　during　lithiation/delithiation　process.　Meanwhile,　the　core-shell　structure　of　multi-walled　carbon　nanotubes/Si　and　Cu　nanowires/Si　minimizes　the　deformation　strain　and　greatly　improves　the　long-term　cycling　performance　in　a　real　battery.　As　a　result,　a　high　specific　capacity　of　1845　mAh　g−1　in　a　half　cell　at　a　current　density　of　3.5　A　g−1　after　180　cycles　with　a　capacity　retention　of　85.1%　has　been　achieved　without　any　conductive　additives　or　binder.　The　demonstrated　three-dimensional　current　collector　coupled　with　Si　anode　might　inspire　new　material　development　on　high-performance　of　lithium-ion　batteries.　©　2019　Elsevier　B.V.
