| 摘 要： | 空气极是整个空气电池中的关键所在，空气极的性能受着防水层的性能、催化层的性能、制备工艺等多种因素的影响．本实验对比了不同含量的聚四氟乙烯、活性碳颗粒等做成的防水层的特性及不同的催化剂(银粉、La-Ca-Co-O等催化剂)做成的催化层的特性．用电化学工作站研究了空气电极的析氧和氧还原特性，认为用碳酸氢铵为造孔剂、用银粉做催化剂的空气电极效果最好．

| Abstract: | Air-electrode is the crucial part of air-zinc battery while the properties of air electrode are affected by the properties of water-proof layer, catalyst layer, the process of the fabrication as well as many other factors. Comparisons have been made between different waterproof layers with diverse PETF and active carbon particle contents and different catalyst layers with silver, La-Ca-Co-O etc as catalyst. Using electrochemical working station to measure the reduction and oxidization properties of oxygen, the conclusion can be drawn that the optimized air electrode consists of NH 4HCO 4 as hole making agent and Ag as catalyst. |
