Overview of Lithium - Ion Battery Binders  Binders, often grouped with conductive agents and additives as "auxiliary materials" in lithium - ion battery production, are crucial and indispensable materials. Their main function is to adhere active materials and conductive agents to current collectors, ensuring electrical contact between powder material particles in the electrode and between the powder materials and the current collector. Binders have a low mass fraction in the electrode and do not participate in electrochemical reactions. Their primary role is to attach active materials and conductive agents to the current collector, maintaining the integrity of the electrode. Binders influence the formation of the solid electrolyte interface (SEI), charge transfer within the electrode and at the electrode - electrolyte interface, the wetting behavior of the electrode, as well as the battery's cycling performance and cost. Therefore, an ideal binder can guarantee the stabil...

PVDF, CMC, PAA, etc.! Research on Lithium Battery Binders LIBs electrodes are mainly composed of electrochemically active electrode materials, conductive additives, binders, current collectors, etc. Among them, binders are an important component of LIBs electrodes. Binders can tightly attach active substances and conductive agents to the current collector to form a complete electrode, prevent the active substances from falling  off and peeling off  during the charge and discharge process , and can evenly disperse the active substances and conductive agents, thereby forming a good electron and ion transmission network and realizing efficient transmission of electrons and lithium ions. The materials currently used as electrode binders include polyvinylidene  fluoride (PVDF), carboxymethyl cellulose (CMC), styrene-butadiene rubber (SBR), polyvinyl  pyrrolidone (PVP), polymethyl methacrylate (PMMA), polyacrylonitrile (PAN),  polyacrylic acid (PAA), polyvinyl alcoho...
