Abstract
The present invention concerns a nickel electrode comprising a nickel-based hydroxide which satisfies at least one of the following criteria: an intensity ratio of the ?103! line to the ?200! line in the X-ray diffraction diagram of 1.05.+-.0.10; a coherence length L of 13.+-.3 nm, a ratio of the sum of the surface areas of the peaks at 3687.+-.10 cm.sup.-1 and 3600.+-.10 cm.sup.-1 to the surface area of the peak at 3580.+-.10 cm.sup.-1 of the Raman spectrum of 0.11.+-.0.03; a ratio of the surface area of the peak at 511.+-.10 cm.sup.-1 to the surface area of the peak at 460.+-.10 cm.sup.-1 in the Raman spectrum of 1.1.+-.0.1.
