摘　　要：将不同比例的铁粉、Fe3 O4和石墨混合均匀 ,制成涂片式铁电极并组装成铁镍蓄电池 ,测定铁电极的充电效率。结果表明 ,含Fe粉 11.75 %～ 47%时 ,充电效率高于其它比例铁粉含量的铁电极 ,可达 80 .9%～ 84.4% ,比充电效率在3 0 %～ 60 %之间的传统铁电极有显著的提高。Iron powder, Fe 3O 4 and graphite were mixed in different proportion, and the Fe electrode was prepared using the mixture and was assembled into Ni Fe battery. The charge efficiency of iron electrode was determined. The result shows that the charge efficiency of iron electrode with the iron powder content within 11.75% -47% is 80.9%-84.4%, which is higher than that with other iron powder content and is much higher than that of traditional iron electrode (with in 30%-60%).
