An electrode for an alkaline electrolyte secondary cell, comprising a current collector supporting a paste containing an electrochemically active material and a binder, characterized in that said binder is a copolymer selected from copolymers of maleic anhydride and a vinyl monomer, said binder being cross-linked after said electrode has been formed.
A process for the production of an electrode according to any one of the preceding claims, comprising the following steps:
- producing said paste by adding a solution of said binder and said cross-linking agent to a suspension of said active material in powder form in water;
- forming an electrode by coating said current collector with said paste;
- and
- carrying out a cross-linking treatment on said electrode.
