采用简单的水热法合成了核桃状CoS 2分级结构。用X射线衍射和扫描电镜对产物的晶相和形貌进行了表征。结果表明,水热法制备的CoS 2是由纳米粒子组成的分级核桃状材料。作为锂离子电池的负极材料,100次循环后的可逆容量达到132.8mAh/g。由于其优异的电化学性能,CoS 2材料可作为LIB的实用阳极材料。
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 batteries (LIBs), reversible capacity of these CoS2 materials reached 132.8 mAh/g after 100 cycles. Due to outstanding electrochemical performance, CoS2 materials can be exploited as a practical anode material for LIBs.
