摘　　要：α相氢氧化镍由于其高放电容量倍受研究者的关注。以Mn作为掺杂元素,在保护气氛下合成了一系列含α相氢氧化镍电池材料,研究了不同掺Mn量及搅拌速度对配位沉淀法合成工艺的影响。用正交试验筛选出合成工艺参数的范围,再通过均匀设计法进一步优化得到最佳的工艺参数:掺锰量为13.3%,搅拌速度为32 r/S,pH为12.5,放电容量达到300 mAh/g,明显高于市售氢氧化镍产品,对含α相氢氧化镍电池材料工业化生产具有一定的指导意义。Alpha phase nickel hydroxide has been widely investigated due to its properties of high discharge capacity. A series of battery material containing Mndopedalpha phase nickel hydroxide were synthesized under protective atmosphere. The effects of different Mn content and stirring intensity on coordination synthesis process were studied and the range of suitableprocess parameters was selected by orthogonal experiment. The process parameters were further optimized by uniform design method as the following results that Mn doped was amount 13. 3%,stirring speed was 32 r /S,pH value was12. 5 and the discharge capacity was 300 mAh /g. It is significantly higher than that of commercially available nickel hydroxide products and it has guiding significance for containing alpha phase nickel hydroxide battery materials in industrial production.
