英文摘要	选取Super-P（SP）、KB或MWCNTs导电碳膜夹层，并置于硫电极与隔膜间组装成扣式锂硫电池.相关评估结果表明，碳膜夹层可显著提高锂硫电池循环性能，硫电极（载硫量为80%，by mass，下同）循环40周后比容量均在800 mAh·g-1以上. 上述三种碳膜的物理性质有较大差异，导致相应电池具有不同电性能. KB碳膜夹层电池呈现较强的电化学极化效应；SP碳膜夹层电池循环初期可释放出最高的比容量，而循环稳定性较差；MWCNTs碳膜可视为较适宜的导电碳夹层材料.; Three kinds of conductive carbon films were prepared with Super-P (SP), KB and MWCNTs, and then the as-prepared carbon films were applied as an interlayer between a sulfur electrode and a separator for constructing a coin-type lithium-sulfur (Li-S) cell, respectively. The assessment results show that all the cells delivered the reversible capacities higher than 800 mAh·g-1 after 40 cycles when the sulfur loading was up to 80% (by mass) in the sulfur electrode. Due to significant differences of physical properties among the carbon materials，the cell with a KB interlayer exhibited higher electrochemical polarization; the cycling performance of the cell with a SP interlayer was poorer than that of the other cells, although the discharge capacity was the highest in the initial cycles; MWCNTs film was the best choice as an interlayer in the Li-S cells.; 中国电子科技集团公司第十八研究所化学与物理电源技术国家重点实验室基金项目（No. 9140C160203120C16074）资助; 作者联系地址：1. 天津大学化工学院，天津 300072；2. 中国电子科技集团公司第十八研究所化学与物理电源技术国家重点实验室，天津 300384; Author's Address: 1.
