γ-PGA (γ-Polyglutamic acid) has both a free a-carboxyl group (-COOH) and an amide (peptide) bond (-NH-CO-) in every repeating unit. The numerous COOH and NH groups form strong hydrogen bonds with the hydroxyl groups (Si-OH) on the surface of silicon and other active materials. The electron-rich oxygen and nitrogen atoms on the amide and carboxylate groups can coordinate with Li+ ions, further strengthening the interface and even potentially facilitating Li+ transport.
