Negative electrode binder performance requirements, test methods and failure mechanisms! Binders have a low mass ratio in the electrode and do not participate in the electrochemical reaction. Their main function is to adhere the active material and the conductive agent to the current collector to keep the electrode intact . Binders affect the formation of the solid electrolyte interface (SEI) , the charge transfer inside the electrode and between the electrode - electrolyte interface , the wetting behavior of the electrode, and the cycle performance and cost of the battery .
Analysis of the influence of slurry quality on coating surface fluctuation｜Lithium battery production process front end (mixing/coating)
Analysis of the influence of slurry quality on coating surface fluctuation｜Lithium battery production process front end (mixing/coating) Lithium battery production process - mixing/coating The production process of lithium batteries varies among different battery manufacturers. Generally speaking, it is divided into three stages: front, middle and back. 1. Front section: pole piece production (Mixing, coating, tableting, baking, slitting, tableting, tab forming) (Core link: coating) 2. Middle section: battery cell assembly (winding or lamination, pre-packaging of cells (into shells), electrolyte injection, sealing) (Core link: winding) 3. Post-processing (activating the battery cell) (battery cell formation, capacity division, static placement, testing, and sorting) (Core links: formation, volume fractionation, and testing)
