Abstract

Oxides and hydroxides of nickel and cobalt forming the active material of alkaline accumulators are treated with a moderately strong acid such as citric acid to remove impurities such as compounds of iron, aluminium, calcium, magnesium, potassium, sodium, zinc, barium, beryllium, and lithium. Purification may be facilitated by applying a reverse charge to the battery before or during the acid treatment, caustic potash solution being used as electrolyte in the first case and the acid used in the purifying treatment being also used as electrolyte in the second case. Alternatively acid potassium citrate may be used as electrolyte.
