COMPOSITION FOR MANUFACTURING AN ELECTRODE, ELECTRODE AND ASSOCIATED METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240039007 titled 'COMPOSITION FOR MANUFACTURING AN ELECTRODE, ELECTRODE AND ASSOCIATED METHOD
Simplified Explanation
The abstract describes a composition for manufacturing an electrode that includes an electrically conductive carbon-based compound, a catalyst-forming species, and cellulose microfibrils encapsulating chitosan. The cellulose microfibrils create a fibrous mesh that binds the composition while limiting coating of the catalyst. This allows the catalyst to remain accessible to the surrounding environment, improving the electrode's electrochemical performances. The composition is also suitable for shaping an electrode using 3D printing.

Original Abstract Submitted
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.
