Abstract
A positive electrode and a negative electrode for an alkaline storage battery and manufacturing methods thereof are provided. The positive electrode includes a nickel porous body formed on a plate, active material particles containing nickel hydroxide and additives filled up into the nickel porous body, a conductive layer coated on the surface of active material particle, and a protective layer coated on the surface of the conductive layer, for increasing the binding force between the active material particles and preventing the contact between the active material particles and an electrolytic aqueous solution.
