Abstract

Disclosed is a method for activating a cell employing a non-sintered type nickel positive electrode. The electrode has metallic cobalt powder and either nickel oxyhydroxide in the range of 60 wt % or less excluding 0 wt % or dischargeable higher oxidized cobalt compound powder whose cobalt has a valence of three or more in the range of 60 wt % or less excluding 0 wt %. The method comprising the steps of resting the cell until the positive electrode potential becomes substantially equal to the equilibrium potential of Co/Co(OH).sub.2, and performing initial charging of the cell, following the resting step.
