A composition for manufacturing an electrode, the composition including an electrically conductive carbon-based compound, at least one species able to form a catalyst, and cellulose microfibrils encapsulating chitosan. The cellulose microfibrils create a fibrous mesh binding the composition while limiting coating of the catalyst. Thus, the catalyst remains accessible to the surrounding environment, to allow the redox reactions at the electrode. The electrochemical performances of the electrode are consequently improved. The composition is furthermore particularly adapted for shaping an electrode by 3D printing.
