摘　　要：研究了空气电极防水层对锌空气电池性能的影响,通过改变防水层中碳材料的种类,PTFE的含量以及烧结温度,得出最佳防水层制备工艺参数,并组装成锌空气电池进行恒流放电测试。测试结果表明,以乙炔黑和PTFE乳液按1∶1混合,然后经过300℃烧结得到的防水层组装的锌空气电池放电性能最好。The effects of diffusion layer of air cathode on the performance of zinc-air battery were investigated. The optimized preparation parameters including the kind of carbon materials, the contented of PTFE and sintering temperature were obtained through a series of experiments. The zinc-air batteries were assembled and discharged in a constant current manner. The results indicate that the discharge capability of zinc-air battery with diffusion layer by mixing acetylene black and PTFE in mass ratio of 1：1 and calcining at 300 ℃ is the best.
