To　buffer　the　volume　expansion　of　silicon　during　charge-discharge　process,　a　3D　carbon-coated　stable　silicon/graphene/CNT　(C@Si/GN/CNT/PDA-C)　composite　was　prepared.　Si　nanoparticles　(SiNPs)　were　first　modified　by　hexadecyl　trimethyl　ammonium　bromide　(CTAB)　to　enhance　their　stability　and　dispersibility　in　water,　then　uniformly　distributed　in　graphene/carbon　nanotubes　(GN/CNT)　by　electrostatic　self-assembly,　and　ultimately　encapsulated　by　carbonized　poly-dopamine　carbon　layer　(PDA-C)　at　high-temperature.　PDA-C　not　only　alleviates　the　volume　expansion　of　Si　and　inhibits　the　direct　contact　of　Si　with　electrolyte,　but　also　acts　as　a　bridge　between　the　conductive　GN/CNT　and　Si　to　maintain　electrode　integrity.　As　an　anode　material　for　lithium-ion　batteries,　the　C@Si/GN/CNT/PDA-C　exhibits　a　superior　reversible　capacity　of　1946　mAh　g　−　1　after　100　cycles　with　the　capacity　retention　of　68.9%　at　a　current　density　of　0.1　A　g　−　1,　and　over　1306　mAh　g　−　1　after　100　cycles　at　1　A　g　−　1.　The　excellent　electrochemical　performance　of　C@Si/GN/CNT/PDA-C　is　attributed　to　the　stable　hierarchical　structure.　©　2021
