Abstract:
A pasted nickel electrode for a storage cell having an alkaline electrolyte, the electrode comprising a current collector and an active mass based on nickel hydroxide in powder form together with a carbon-based conductor, the electrode being characterized by the fact that said carbon-based conductor is made up of particles of carbon that withstand electrochemical oxidation and that satisfy the following relationship:W>0.025 in units of 10.sup.9 g/m, whereW=TC002/S.times.G, whereTC002 is the size of the [002] crystallite on the X-ray diffraction pattern expressed in nanometers;S is the specific surface area of the particles expressed in m.sup.2 /g;G is the graphitization coefficient of the carbon defined as follows:G=(d002-0.3354)/(0.3450-0.3354)d002 is the lattice constant in the 002 direction in nanometers.
