Vapor-grown carbon fibers （VGCFs） were introduced as conductive additives for sulfur-multiwalled carbon nanotubes （S-MWCNTs） composite cathode of lithium-sulfur batteries. The performance of S-MWCNTs composite cathodes with carbon black and VGCFs as sole conductive additives was investigated using scanning electron microscopy （SEM）, galvanostatic charge-discharge tests and electrochemical impedance spectroscopy （EIS）. The results show that the S-MWCNTs composite cathode with VGCFs displays a network-like morphology and exhibits higher activity and better cycle durability compared with the composite cathode with carbon black, delivering an initial discharge capacity of 1254 mA＆#183;h/g and a capacity of 716 mA＆#183;h/g after 40 cycles at 335 mA/g. The interconnected VGCFs can provide a stable conductive network, suppress the aggregation of cathode materials and residual lithium sulfide and maintain the porosity of cathode, and therefore the electrochemical performance of S-MWCNTs composite cathode is enhanced.

以不同粒度范围的石油焦为原料，KOH为活化剂，采用化学活化工艺制备了超级电容器用活性炭电极材料。采用N2吸附法表征了活性炭材料的BET比表面积及孔结构；在1mol／L的Et4NBF4／AN有机电解液体系下组装成模拟电容器，并考察了活性炭材料的电化学性能。结果表明：随着原料粒度的减小，活性炭的振实密度和收率先增大，然后再减小。原料粒度范围越窄，活性炭具有越小的BET比表面积和孔容。在1mol／L的Et4NBF4／AN电解液体系下，随着石油焦粒度的不断减小，活性炭材料的质量比容量不断增大，在粒度〈38μm时取得最大值140F／g。粒度为38-44μm的石油焦制备出的活性炭在1A／g电流下质量比容量为126．6F／g，在20A／g电流下质量比容量为116．2F／g，容量衰减只有8．2％，表现出良好的功率特性。
