The invention proposes a composition comprising: The invention also relates to an anode comprising the composition according to the invention. The invention also relates to an alkaline electrolyte battery comprising said at least one anode.

Composition for negative electrode of alkaline electrolyte battery

A positive active material for nickel electrodes of alkaline storage batteries consists of particles of hydroxide containing mainly nickel and covered with a layer of a hydroxide phase based on nickel and yttrium. The proportion of the hydroxide phase is in the range 0.15% to 3% by weight of yttrium expressed as yttrium hydroxide relative to the total weight of particles.

Positive active material for alkaline electrolyte storage battery nickel electrodes

A non-sintered nickel electrode for alkaline electrolyte storage cells including a current collector and a paste containing an active material based on nickel hydroxide and a conductive material, wherein said conductive material is a lithium-containing cobalt and nickel oxide whose degree of oxidation obtained after electrochemical conditioning is stable after prolonged storage in the alkaline electrolyte.

Non-sintered nickel electrode for an alkaline electrolyte secondary electrochemical cell

A method of manufacturing a positive active material for nickel electrodes of alkaline storage batteries which consists of particles of hydroxide containing mainly nickel and covered with a layer of a hydroxide phase based on nickel and yttrium is disclosed. The proportion of the hydroxide phase is in the range 0.15% to 3% by weight of yttrium expressed as yttrium hydroxide relative to the total weight of particles.
