Effects of Aniline Tetramer-Co-Acrylic Monomer Grafted to Polysaccharide Backbone As a Conductive and Adhesive Binder for High Capacity Si/C Composite Anodes

摘要

Conducting polymers such as polyaniline and polypyrrole have been sometimes described as a potential candidate binder for high silicon anode materials due to its low price, high conductivity, and simple synthesis. The manufacturing process of conducing polymerbased electrodes requires environmental-unfriendly organic solvents such as n-methylpyrrolidone. Due to the drawback, natural polysaccharides blended with the conductive polymers have been often investigated as water-soluble, electronically conductive, and adhesive binder to improve the electrochemical performance of the high-capacity Si anodes. However, the polymer blends are still needed to modify their properties through functionalization with some additional groups, for example, grafting with adhesive monomers and crosslinking for high adhesion strength.
