Substrate for alkaline storage battery, process for producing the same and alkaline storage battery |
摘要 |
An improved sintered nickel porous plaque substrate for alkaline storage batteries is prepared by a process which includes coating the surface of the sintered nickel powder with a nickel oxyhydroxide coating by anode oxidation in an alkali solution, then attaching a cobalt salt to the nickel oxyhydroxide coating and, while subjecting the cobalt salt to an alkali conversion treatment, through an oxidation-reduction reaction between nickel oxyhydroxide and cobalt hydroxide, converting the nickel oxyhydroxide coating into a nickel hydroxide coating and forming a cobalt oxyhydroxide layer as a uniform film on the outside of the nickel hydroxide coating.
