Carbon spheres CSs ) derived from different raw materials are proved to be good sulfur hosts for Li S battery cathode materials. But there is little attention about activated carbon spheres ACSs) with different particle sizes and specific surface areasareas. In this paper, CSs with particle sizes were prepared with glucose by hydrothermal method and activated by KOH. Three ACSs with particle sizes were used to load with sulfur as cathodes of Li-S batteries to analyze the effects of different specific surface areas on battery performance. Electrochemical measurements show that the larger the specific surface area and particle size, the better the battery performance..
