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...

Analysis of manufacturing processes of lithium batteries with different packaging methods: square, cylindrical, and soft pack Automotive Technician ,praise In the new energy era, lithium batteries are the core power and energy storage unit, and their importance is self-evident. Among the many characteristics of lithium batteries, the external form of packaging shape actually contains complex technical considerations and process logic. The three mainstream packaging shapes of square, cylindrical, and soft pack each correspond to a unique process, like three keys, opening the door to different application scenarios. This article will deeply analyze the technical routes and process secrets behind these three lithium battery packaging shapes.
