Abstract

A nanocomposite material (SnO~2~Co~3~O~4~) has been synthesized as an anode material for lithium‐ion batteries by the molten salt method. Characterization by X‐ray diffraction (XRD) and transmission electron microscopy (TEM) showed that the composite has a small particle size. The electrochemical performance was examined, including the charge–discharge and cycling properties. The experimental results showed that the sample containing the highest amount of Co~3~O~4~ compound exhibited a specific capacity of 355 mAh g^−1^ after 40 cycles, with cycling at 70 mA g^−1^ (35.2% higher than for the sample containing a lower amount of Co~3~O~4~). It seems that increasing the amount of Co~3~O~4~ can give good capacity retention and high specific capacity.
