Tin and graphite based nanocomposites: Potential anode for sodium ion batteries

► Tin and graphite mixture and nanocomposites have been synthesized by high energy mechanical milling (HEMM). ► Mechanically milling results in nanocrystalline nanocomposites. ► The mechanically milled nanocomposites exhibit stable capacities of ∼410 mAh g−1. ► Electrochemical response varies with duration of mechanical milling. ► Good electrochemical response of the nanocomposite is due to structural stability.
