A scalable ternary SnO2–Co–C composite as a high initial coulombic efficiency, large capacity and long lifetime anode for lithium ion batteries

A new ternary SnO₂–Co–C composite has been synthesized by facile and scalable ball milling, which demonstrates a high initial coulombic efficiency (ICE, with average of 80.8%), high reversible specific capacity and a long lifetime (610 mA h g⁻¹ after 1000 cycles at 2 A g⁻¹).
