Synthesis of Mn-substituted Nickel Hydroxide

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.
