The positive nickel electrode which does not irreversibly lose capacity during storage, comprises a current collector, active material based on crushed nickel hydroxide and a carbon-based conductor, formed from carbon particles which are resistant to oxidation. A thickened out nickel electrode for an alkaline accumulator, comprises a current collector and active material based on crushed nickel hydroxide and a carbon-based conductor, formed from carbon particles which are resistant to oxidation and satisfy: (W) ≥ 0.25 10<9>gm<-1>; where W = TC002/S x G. TC002 = crystal size (nm); S = specific surface area (m<2>/g; G = graphite coefficient; G = (d002 - 0.3354)/(0.3450 - 0.3354); d002 = linking distance in direction 002 (nm). |
