Alkalische Sammlerbatterie und Verfahren zur Herstellung von Ni/Co-Hydroxid-Aktivmasse für positive Elektrode

摘要

Provided are alkaline storage batteries which are higher in active material utilization as compared with conventional batteries and which can maintain the high utilization even after long-term charge-discharge cycle. Cobalt hydroxide having a BET specific surface area of 20-30 m<2>/g and obtained by neutralization reaction of a cobalt salt solution and an aqueous alkali solution in the presence of a reducing agent is added to a positive electrode active material.
