研究了用碳纤维插层化合物快速加热合成的剥离碳纤维（ExCFs）作为双电层电容器（EDLC）电极。EDLC的测定采用标准的三电极电池，电解液为1 mol/dm3硫酸。制备的excf的电容达到117 F/g，尽管它们的相对表面积约为330 m2/g。ExCFs经空气活化后，其BET表面积略有增加，但EDLC的电容增大至160 F/g。excf的电容很大程度上依赖于其BET表面积，这与活性炭纤维的依赖关系不同。
Exfoliated carbon fibers (ExCFs) synthesized through the rapid heating of intercalation compounds of carbon fibers were examined as electrodes of electric double layer capacitors (EDLC). The measurement of EDLC was performed using a standard three-electrode cell with 1 mol/dm3sulfuric acid electrolyte. The capacitance of as-prepared ExCFs reached 117 F/g, even though they had a relativity small surface area of about 330 m2/g. After air activation of ExCFs, the BET surface area increased slightly, but the capacitance of the EDLC increased up to 160 F/g. Capacitance of ExCFs strongly depended on their BET surface area, having a different dependence from that reported on activated carbon fibers.
