摘　　要：以纸纤维为基体,以碳纳米管为导电剂,采用普通造纸工艺将两者复合制备出具有一定强度和柔韧性的碳纳米管纸。采用X射线衍射、扫描电子显微镜、四探针电阻仪对样品进行表征。结果表明,当碳纳米管与纸纤维以质量比1∶1掺杂时,碳纳米管纸代替石墨片作为锌锰电池集流体,锌锰电池放电能力提高64%,采用石墨化碳纳米管纸时,锌锰电池放电能力提高100%,达到15 m A·h。随着碳纳米管含量增加,锌锰电池放电能力也随之提高。A kind of strong but highly flexible CNT paper is prepared by traditional paper-making process with pulp fibers as carriers and CNTs as conductive agent, which is used to improve the discharge property of zinc-manganese battery. The obtained products are characterized by X-ray diffraction （ XRD ）, scanning electron microscopy （ SEM ） and four-point probes（4PP）. The results show that the discharge performance of zinc-manganese battery is increased by 64% when the CNT paper with 1 ： 1 mass ratio of pulp fibers and CNTs is employed to replace the graphite as current collector. More importantly, when zinc-manganese battery is modified by the graphitized CNT paper, the discharge capacity is improved by 100% and can reach 15 mA-h. Increasing the content of CNT paper leads to the increase of discharge capacity of zinc-manganese battery.
