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)
Introduction to lithium battery production process, process flow, principle, formula, and parameters
Introduction to lithium battery production process, process flow, principle, formula, and parameters Introduction丨 mybattery The number of companies and practitioners engaged in lithium battery production is the largest in the entire industry chain, and many new people join the industry every day. This article shares with you the introduction of each process, working principle, formula, parameters, and process flow of lithium batteries. I hope it will be helpful for everyone's study. 01 Mixing process Mixing process 1. Mixing process (1) Function: The batching process is actually to mix the various components in the slurry in a standard proportion and prepare the slurry to facilitate uniform coating and ensure the consistency of the electrode. (2) Slurry related parameters: a. Viscosity: The resistance of a fluid to flow. Viscosity is a property of a fluid. When a fluid flows in a pipe, there are three states: laminar flow, transitional flo...
