Abstract
A method of producing a nickel electrode comprising a current collector and active material pressed into physical and electrical contact with the current collector. The active material comprises nickel hydroxide, an organic binder, a conductive diluent and a cobalt compound, the cobalt compound having been precipitated from a cobalt-containing solution in contact with the already-formed nickel hydroxide.

A method of producing a pressed nickel electrode comprising the sequential steps of:
- (a) contacting nickel hydroxide powder with a solution containing cobalt ions and precipitating a cobalt compound from said solution onto the nickel hydroxide powder,
- (b) mixing the nickel hydroxide powder containing said precipitated cobalt compound with a powdered conductive diluent and a powdered binder to form a resultant mixture, and
- (c) pressing the resultant mixture into physical and electrical contact with a current collector.
A method of producing a pressed nickel electrode comprising the sequential steps of:
- (a) mixing nicle hydroxide powder with a powdered conductive diluent and a powdered binder to form a resultant mixture,
- (b) pressing the resultant mixture into physical and electrical contact with a current collector, and
- (c) contacting said pressed resultant mixture with a solution containing cobalt ions and precipitating a cobalt compound from said solution onto said pressed resultant mixture.
