Hydrothermal synthesis and electrochemical performance of walnut-like CoS2 hierarchical structures

Walnut-like CoS2 hierarchical structures were synthesised by a simple hydrothermal method. The crystalline phase and morphology of the products were characterised with X-ray diffraction and scanning electron microscope, respectively. The results showed that CoS2 prepared by hydrothermal method were hierarchical walnut-like materials consist of nanoparticles. As an anode material of Li ion batterie...
