中文摘要：
以椰壳为碳源、KOH为活化剂，在不同的碱碳比下制备具有微孔结构的活性炭。当碱碳比为5和4时，制备得比表面积分别为2918m。／g和3125m。／g的活性炭，碘吸附值分别为2718．613mg／g和2831．014mg／g。将硫与制得的活性炭以质量比7：3进行复合，作为正极组装锂硫电池。以100mA／g的电流在1．5～2．8V充放电，碱碳比为5和4的活性炭组装的电池的首次充放电容量分别为1250．8mAh／g和l301．0mAh／g。
英文摘要：
Coconut shell activated carbon with microporous structure was synthesized by using coconut as carbon source and KOH as activator. The specific surface areas of the obtained activated carbon, under the alkali carbon ratio of 5 and 4,were 2 918 m2/g and 3 125 m2/g,the iodine adsorption value of them were 2 718.613 mg/g and 2 831. 014 mg/g,respectively. Sulfur and prepared activated carbon （AC） were composed with a mass ratio of 7： 3, as the cathode to assemble lithium-sulfur battery. When charged-dis- charged in 1.5 ~ 2. 8 V with the current of 100 mA/g, the initial specific discharge capacities of assembled battery with the alkali carbon ratio of 5 and 4 were 1 250. 8 mAICg and 1 301.0 mAh/g,respectively.
