Lithium-Ion Battery Manufacturing Process Guide

This document provides a comprehensive overview of the lithium-ion battery manufacturing process, focusing on the three major enemies of batteries: moisture, particles, and timeliness. It details the environmental requirements for temperature, humidity, and cleanliness in electrode, assembly, and formation sections. The electrode section process flow includes slurry mixing, coating, rolling, and slitting/die cutting. Slurry mixing involves combining raw materials to achieve a uniform suspension, with control points for workshop temperature, humidity, cleanliness, and material properties. Coating applies the slurry onto current collectors, impacting battery capacity and safety. The document also covers assembly and formation sections, emphasizing the importance of dew point and humidity control. Key process parameters and quality checks are outlined to ensure battery consistency and performance.
