Co2SnO4–multiwalled carbon nanotubes composite as a highly reversible anode material for lithium-ion batteries

We report a facile strategy to synthesize the composite of Co2SnO4 nanoparticles and multiwalled carbon nanotubes (MWCNTs) as a highly reversible anode material for high-performance lithium-ion batteries. Galvanostatic charge/discharge, cyclic voltammograms(CVs) and electrochemical impedance spectra (EIS) testing results indicate that the Co2SnO4–MWCNTs composite display large reversible capacity, excellent cyclic performance and good rate performance, highlighting the importance of the added MWCNTs for maximum utilization of electrochemically active Co2SnO4 nanoparticles for energy storage applications in high-performance lithium-ion batteries.
