Abstract: An aqueous nickel hydroxide paste for the mechanical impregnation of fibrous-structure electrode frameworks. The polydisperse solid total system of solid particles in the nickel hydroxide or hydrated nickel oxide paste has a particular particle-size distribution (distribution ogive) which may vary within narrow limits and is preferably evaluated in a RRSB particle-size grid according to P. Rosin, E. Rammler, K. Sperling and I. G. Bennett. The resulting paste can be filled into differing frameworks in one operation, as a moist active mass (paste), to a degree of filling of 94% to 100%, without constituents of the paste (particularly at the lower edge during handling in the vertical position) draining off or escaping again. Preferably, the choice of the particle-size distribution of the nickel hydroxide powder used is so fine that the technical comminution work in the production of the paste is very small and that the production times for the paste can consequently be substantially reduced.
