摘　　要：将锌粉与聚丙烯腈(PAN)的N-N二甲基甲酰胺(DMF)溶液共混配置纺丝液,采用湿法纺丝技术制备Zn/PAN复合纤维,即纤维状锌空气电池阳极。利用扫描电子显微镜及热重分析技术对纤维状锌空气电池阳极进行物理化学性能测试。在纤维状锌空气电池阳极表面依次缠绕m(NH 4Cl)∶m(KCl)=2∶1的电解质溶液水性薄膜和导电双面胶组装纤维状锌空气电池,并研究该空气电池的放电性能。结果表明,当PAN纺丝液中添加锌粉的质量分数为15%时,得到纤维状锌空气电池具有较好的电学性能,其开路电压为0.8~1.1 V,电流平均值为0.11 mA。Zinc powders were blended with polyacrylonitrile/N-N dimethyl formamide(PAN/DMF)solution followed by wet spinning technique to prepare Zn/PAN composite fiber and was used as fibrous anode for zinc-air battery.Scanning Electron microscope(SEM)and thermogravimetric analysis(TG)technology were used to test the physicochemical properties of fibrous zinc-air battery anode.Fibrous zinc-air batteries were assembled by wrapping a water-based film of electrolyte solution with m(NH 4Cl)∶m(KCl)=2∶1 on the anode surface of fibrous zinc-air batteries and conductive double-sided adhesive.The results demonstrated that the fibrous zinc air battery anode from 15%mass fraction of zinc powders in PAN/DMF spinning solution,obtained the optimal electrical performance with its open circuit voltage of 0.8~1.1 V and average discharge current of 0.11 mA.
