Nickel electrode for alkaline secondary battery and alkaline secondary battery

摘要

The nickel electrode for alkaline secondary battery according to the present invention is obtained by applying a paste containing active material particles comprising nickel hydroxide to a conductive substrate and drying the paste on the conductive substrate. In the above-mentioned nickel electrode for alkaline secondary battery, a conductive layer comprising sodium-containing cobalt oxide is formed on a surface of the active material particles and tungsten powder and/or tungsten compound powder is added on the active material particles.
