Lignin is a highly branched, three-dimensional macromolecule rich in phenolic hydroxyl (-OH), carboxyl (-COOH), and methoxy (-OCH3) groups. Unlike linear binders (like PVDF), lignin’s 3D branched structure allows it to form a more stable and rigid network that "cages" active material particles. Its polar groups form strong hydrogen and covalent bonds with the current collector (copper or aluminum) and active materials like Silicon (Si) or Hard Carbon, preventing delamination. Moreover, lignin contains quinone & hydroquinone functionalities and these groups can undergo reversible redox reactions during battery cycling. This means the binder itself contributes to the battery's overall capacity, rather than just acting as glue.
