摘　　要：以葡萄糖溶液为原料,通过水热和高温碳化两步法制备了单分散的碳微球.采用X射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、拉曼光谱、物理自动吸附仪(ASAP 2020)、场发射扫描电镜(FESEM)和透射电子显微镜(TEM)对材料的结构、形貌、组成以及表面特性进行了表征.用循环伏安、恒流充放电等电化学方法对其电化学性能进行了测试,结果表明:碳微球通过堆积形成微米级多孔网络结构,为电解液离子嵌入-脱出提供了有效的通道,从而这种碳微球具有良好的电化学性能。carbon microspheres（CMSs）were synthesized via hydrothermal process by following a high temperature carbonization,in which glucose was used as raw materials. The morphology, microstrueture, components and surface fea- tures of the as-obtained samples were characterized by SEM,TEM ,XRD,Raman ,FTIR and BET. The electrochemical be- haviors of the product was evaluated by cyclic voltammetry and galvanostatic charge-discharge. The results indicated that CMSs could form porous network structure, which provided a fast path for the insertion and extraction of electrolyte ions. Therefore,CMSs exhibited excellent electrochemical behaviors.
