Abstract:
A method of fabricating a positive electrode comprising the steps of:a) providing a powder mixture comprising nickel hydroxide active material and a binder wherein said nickel hydroxide is co-precipitated with 3 to 5 weight per cent zinc and 1 to 2 weight per cent cobalt; b) combining said powder mixture with a solvent to form a paste; c) providing a two-dimensional electrically conductive substrate having at least a first major substrate surface and a second major substrate surface opposing said first surface; d) applying said paste to at least a portion of said first and second substrate surfaces; and, e) drying said paste to form a final electrode coating, wherein the thickness of said substrate is between 10 and 50 per cent of the thickness of said electrode.
