1. Electrode Manufacturing. Lets Take a look at steps in Electrode Manufacturing. Step 1 – Mixing. The anode and cathode materials are mixed just prior to being delivered to the…

The anode and cathode materials are mixed just prior to being delivered to the coating machine. This mixing process takes time to ensure the homogeneity of the slurry. Cathode: active material (eg NMC622), polymer binder (e.g. PVdF), solvent (e.g. NMP) and conductive additives (e.g. carbon) are batch mixed. Anode:active material (eg graphite or gra...

The anode and cathodes are coated separately in a continuous coating process. The cathode (metal oxide for a lithium ion cell) is coated onto an aluminium electrode. The polymer binder adheres anode and cathode coatings to the copper and aluminium electrodes respectively.

Immediately after coating the electrodes are dried. This is done with infrared heating on a continuous process. The solvents are recovered from this process.

Battery Manufacturing Basics from CATL’s Cell Production ... - Medium

medium.com › batterybits › battery-manufacturing-basics-from-catls-cell-production

This story is contributed by Katherine(Qianran) He and Yen T. Yeh In many universities and startup-scale battery R&D environments, the coin cell is the default form factor to evaluate battery systems. However, in applications such as electric vehicles (EV), “cells” are typically manufactured in pouch, prismatic, or cylindrical form factors, which are then assembled into “modules”, “packs”, and then integrated into the EV product. In order to achieve stringent safety and performance requirements, a high level of precision, uniformity, stability, and automation have become necessary in the battery manufacturing process. This work is a summary of CATL’s battery production process collected from publicly available sources in Chinese media (ref. 1 , 2 , 3 ). CATL (Contemporary Amperex Technology Co. Limited) is the largest battery manufacturer in the world, and its battery production process is sophisticated and highly automated. Although much of the details of the manufacturing process are proprietary, we have identified and outlined the 3 main production stages and 14 key processes below from publicly available sources as an introduction to battery manufacturing.
