리튬 배터리는 어떻게 만들어지나요? Posted by batterymanufactory.com
Making lithium batteries involves several intricate steps and the careful assembly of various components. Here's a comprehensive breakdown of the process: Part 1: How Lithium Batteries are Made Step 1: Making Electrode Materials: Cathode materials like lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), or nickel-manganese-cobalt oxide (NMC); Anode materials typically graphite or sometimes silicon. Process: Materials are mixed with conductive binders and solvents to form a slurry. Slurry is coated onto metal foils (cathode on aluminum, anode on copper) using tools like slot dies or doctor blades. Step 2: Drying and Cutting Drying: Coated foils are dried in ovens to remove solvents. Cutting: Electrode sheets are cut to precise shapes and sizes using slitting machines. Step 3: Stacking and Filling Stacking: Electrodes (cathode and anode) and separators (polyolefin-based) are assembled in the desired configuration (cylindrical, prismatic, etc.). Filling: Elect
