Abstract：
 Water solution of nickel sulfate and water solution of sodium hydroxide containing complexing agent and additive and with dissolved salt of doped element are first compounded; water solution of cobalt sulfate and water solution of sodium hydroxide containing complexing agent are then compounded; all the solutions are finally made to react chemically in a reactor and the reacted solution is shifted to an aging tank to obtain nanometer level spherical alpha-nickel hydroxide product. The process of the present invention is simple and has easily controlled technological parameters and the product has small positive pole expansion, high specific capacity, large charging and discharging capacity and high practical value.
