PURPOSE:To obtain active material for nonsintered plate of alkaline storage battery high filling rate and efficiency by reacting salt solution and alkali soultion in an excess of alkali, and removing free alkali and drying and washing the reaction product. CONSTITUTION:Salt solution of active material such as nickel nitrate and alkali solution such as sodium hydroxide are mixed and reacted in an excess of alkali. The reaction product obtained is filtered and free alkali is removed so that residual alkali becomes 0.7-5.0wt%. Then this product is dried and washed and dried again to obtain active material. By this process, active material for alkaline storage battery having high filling rate and efficiency is obtained, and performance of nonsintered plate is improved. |
