Abstract (en)

[origin: WO2004032260A2] The invention relates to cathode active material based on mixed nickel hydroxide which is used for alkaline batteries and has a special bimodal particle-size distribution providing said material with high-performance characteristics. The inventive material based on mixed nickel hydroxide is produced by means of a very advantageous continuous precipitation process in a closed flow reactor which is provided with an integrated decantation area.
