Verfahren zur Herstellung von positivem Elektrodenaktivmaterial für alkalische Sekundärbatterie |
摘要 |
The present invention is to provide a production method of an active material for an alkaline secondary battery comprising: a step of mixing particles comprising particles mainly containing nickel hydroxide and particles of a metal cobalt or a cobalt compound in a mixer with a sealed structure comprising a heating means in the presence of oxygen and an alkaline aqueous solution while heating. An active material produced by the method allows a high utilization. And a battery assembled with a positive electrode using the active material has an excellent high ratio discharge characteristic, and hardly causes the capacity decline even at the time of recharging after leaving in the over discharge state for a long time. <IMAGE> |
