Abstract
The invention relates to a structure of a positive electrode possessing improved electrical capacity and intended for electrochemical generators working with a liquid electrolyte. It comprises, on the one hand, a metallic collector of high porosity, in particular of the non-woven fibrous type or of the isotropic, cross-linked type of open porosity and, on the other hand, a nickel hydroxide-based active material filling in part the pores of the collector and containing cobalt. This structure is characterized by a heterogeneous dispersion of the cobalt within the active material.
