Electrochemical Performance of Co S Microspheres Synthesized by Hydrothermal Method as Anode Material for Li-ion Batteries

Co S microspheres were prepared by hydrothemal method. TEM and XRD were employed to analysized the characteristics of samples,and the electrochemical behavior were studied by Li-ion batteries assembled. The results show that the as-prepared Co S microspheres exhibited good initial reversible capacity,however the subsequent cycle stability was poor,which may be attributed to the dissolution of Li2 S produced by lithiation.
