The　amorphous　carbon　was　coated　on　the　surface　of　the　nano-silicon　with　citric　acid　by　a　simple　mechanical　stirring　in　water　bath　method　and　high　temperature　pyrolysis　method,　and　then　the　carbon-coated　silicon　composite　material(Si@C)　was　coated　with　polyvinyl　alcohol　by　the　secondary　mechanical　stirring　and　high　temperature　pyrolysis　to　obtain　double　carbon　layer-coated　silicon　composite　material　(Si@C@C).　The　microstructure　and　surface　morphology　of　Si@C@C　were　characterized　by　X-ray　diffraction　(XRD)　and　scanning　electron　microscopy　(SEM).　The　electrochemical　properties　of　Si@C@C　were　investigated　by　constant　current　charge-discharge,　cyclic　voltammetry,　and　electrochemical　impedance　spectra　techniques.　The　study　found　that　the　first　reversible　specific　capacity　of　Si@C@C　was　1669　mAh/g　at　the　current　density　of　0.1　C.　The　specific　capacity　remained　at　1300　mAh/g,　while　the　capacity　retention　rate　was　77.9%　after　200　cycles.　The　cyclic　stability　of　Si@C@C　was　higher　than　that　of　Si@C,　which　greatly　improved　the　electrochemical　performance　of　silicon-based　materials　as　anode　materials　for　lithium　ion　batteries.
