Abstract
The invention relates to a new method of manufacturing a nickel hydroxide electrode wherein the electrochemically active nickel hydroxide is formed in the pores of a nickel structure by reacting the nickel of said structure with a gas which forms a salt therewith in situ capable of reacting with an alkali metal hydroxide to form nickel hydroxide. The invention also relates to the prepared electrode and to an alkaline storage battery containing the same as well as to the use of said electrode in an alkaline storage battery.
Claims14
In the method of manufacturing a nickel hydroxide electrode having a sintered, porous nickel structure by forming electrochemically active material in the pores of the structure through activation of nickel from the structure, the improvement which comprises reacting the nickel of the structure with a gas which forms a nickel salt in situ capable of reacting with an alkali metal hydroxide to form nickel hydroxide and then reacting said salt with an alkali metal hydroxide to form nickel hydroxide in the pores of the nickel of said structure.
A porous nickel hydroxide electrode produced by reacting a sintered, porous nickel structure with a gas which forms a nickel salt in situ capable of reacting with an alkali metal hydroxide to form nickel hydroxide, then reacting said salt with an alkali metal hydroxide to form a porous nickel hydroxide structure, all of the nickel hydroxide in said porous nickel hydroxide structure having been formed from the nickel in said sintered, porous nickel structure, and then forming said porous nickel hydroxide structure into an electrode.
