Pyrite　(FeS2)　is　known　for　one　alternative　to　the　promising　anode　materials　for　lithium-ion　batteries　(LIBs)　on　account　of　the　low　price,　friendliness　to　environment　and　comparable　higher　theoretical　capacity.　Nonetheless,　its　long-term　cycling　performance　is　still　not　satisfied.　In　our　present　work,　a　FeS2@carbon　composite　coated　with　reduced　graphene　oxide　(rGO)　(rGO@FeS2@C)　was　synthesized　to　settle　this　problem.　With　the　addition　of　rGO,　the　huge　volume　change　was　relieved　and　the　big　pulverization　was　also　alleviated.　When　applied　as　the　anode　material　for　LIBs,　the　rGO@FeS2@C　electrode　could　deliver　outstanding　electrochemical　performance　owing　to　its　special　structure.　At　1　A　g(-1),　it　could　exhibit　a　high　specific　capacity　of　820.7　mA　h　g(-1)　after　300　cycles.　Even　if　when　the　current　density　reaches　to　a　higher　degree　of　5　A　g(-1),　rGO@FeS2@C　could　still　exhibit　a　great　specific　capacity　to　600.8　mA　h　g(-1)　in　the　wake　of　1100　cycles,　which　is　one　of　the　best　results　to　FeS2　systems.　In　addition,　we　also　compare　its　performance　with　the　commercialized　FeS2,　further　confirming　the　good　electrochemical　properties　of　rGO@FeS2@C.
