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.

Composition for manufacturing an electrode, electrode and associated method

The present invention relates to a printing or spray deposition method for preparing a supported flexible electrode and to a method for manufacturing a lithium-ion battery.

Printing or spray deposition method for preparing a supported flexible electrode and manufacture of a lithium-ion battery

A method for preparing self-supporting flexible electrodes is provided using refined cellulose fibers as binder. The negative or positive self-supporting flexible electrode is obtained by such method. A Li-ion battery is also provided in which at least one electrode is a self-supporting flexible electrode.
