摘　　要：用均相沉淀法制备出了纳米氧化镍,所选取的原料和沉淀剂价廉易得,沉淀效果好,工艺路线简单易行.探讨了原料配比、沉淀剂滴加速率、pH值和反应时间对氧化镍生成量的影响.并且确定了较优的工艺条件.将所制取的纳米氧化镍应用于铁镍蓄电池,研究其电化学性能,比较了纳米氧化镍蓄电池和普通氧化镍蓄电池的充放电性能,前者的充放电性能明显优于后者.A nano- nickel oxide is prepared by the homogeneous sedimentation method. The selected materials and precipitating agent are low priced and easily obtain and the effect is better . The technological process is simple and easy. Influences of materials ratio and precipitating agent rate and pH value and reacting time to yield of nano-nickel oxide were inquired technological conditions are determined. And "experiment Fe -Ni storage cell with the nano-nicke oxide was made. Its electrical and chemical properties...
