PURPOSE:To easily produce a nickel electrode for a battery having high active material utilization and long life by adding cobalt powder in a process in which nickel hydroxide precipitate obtained by mixing nickel salt solution and caustic alkali solution is washed and collected, and drying them. CONSTITUTION:Nickel hydroxide is precipitated by mixing nickle salt solution and caustive alkali solution. Cobalt powder is added in a process in which the precipitate is washed and collected. This mixture is dried or partially dried to prepare an active material mixture. The active material mixture obtained by this process has high utilization, and a long life nickel electrode for a battery is easily manufactured by using this mixture. |
