CCS (Carboxymethyl Chitosan) is a remarkable and highly promising biopolymer binder that is gaining significant attention in battery research, especially for next-generation, high-capacity chemistries. Carboxymethyl Chitosan is created by introducing carboxymethyl (-CH2\-COOH) groups onto the chitosan backbone, typically at the C6 and/or N2 positions. This modification yields several key properties: (1) Neutral pH solubility; (2) The binder now possesses both the native amino (-NH2) and hydroxyl (-OH) groups from the chitosan backbone plus the newly introduced carboxylate (-COO-) groups. This abundance of strong, polar functional groups enhances adhesion by forming multiple hydrogen bonds and ionic bonds with the metal oxide surface of active materials like silicon (SiOx) and the metal current collector (e.g., copper).
