Tin-based　nanocomposite　materials　embedded　in　carbon　frameworks　can　be　used　as　effective　negative　electrode　materials　for　lithium-ion　batteries　(LIBs),　owing　to　their　high　theoretical　capacities　with　stable　cycle　performance.　In　this　work,　a　low-cost　and　productive　facile　hydrothermal　method　was　employed　for　the　preparation　of　a　Sn/C　nanocomposite,　in　which　Sn　particles　(sized　in　nanometers)　were　uniformly　dispersed　in　the　conductive　carbon　matrix.　The　as-prepared　Sn/C　nanocomposite　displayed　a　considerable　reversible　capacity　of　877　mAhg(-1)　at　0.1　Ag-1　with　a　high　first　cycle　charge/discharge　coulombic　efficiency　of　about　77%,　and　showed　668　mAh/g　even　at　a　relatively　high　current　density　of　0.5　Ag-1　after　100　cycles.　Furthermore,　excellent　rate　capability　performance　was　achieved　for　806,　697,　630,　516,　and　354　mAhg(-1)　at　current　densities　0.1,　0.25,　0.5,　0.75,　and　1　Ag-1,　respectively.　This　outstanding　and　significantly　improved　electrochemical　performance　is　attributed　to　the　good　distribution　of　Sn　nanoparticles　in　the　carbon　framework,　which　helped　to　produce　Sn/C　nanocomposite　next-generation　negative　electrodes　for　lithium-ion　storage.
