Nickel eletrode for secondary battery

摘要

Disclosed is a nickel electrode for secondary battery, which ensures high packing density of an active material and improvement in a efficiency factor of the active material. The nickel electrode comprises a current collector supporting an active mixture material containing Ni(OH)2 powder and CoO powder and/or Co(OH)2 powder as essential components, wherein said Co(OH)2 powder and/or CoO powder are spherical or almost spherical in shape.
