The lithium battery cell production process flow is a complex, multi-step manufacturing sequence that transforms raw materials into functional lithium-ion battery cells, requiring precision and strict quality control at each stage to ensure performance and safety. The process can be divided into electrode preparation, cell assembly, electrolyte filling, formation, and aging.
Electrode preparation is the first critical step. It begins with mixing active materials, conductive agents, and binders into a slurry. For the cathode, active materials may include lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), or nickel-cobalt-manganese (NCM) compounds; the anode typically uses graphite. The slurry is coated uniformly onto a metal foil substrate—aluminum for the cathode and copper for the anode—using slot-die coating machines to ensure consistent thickness (10–100μm). The coated foils are dried in ovens to remove solvents, then calendared (compressed) to increase density and improve conductivity. Finally, the foils are slit into narrow strips of the desired width, with tabs welded onto the ends to connect to the cell’s terminals.
Cell assembly involves stacking or winding the electrodes. In the stacking method, layers of cathode, separator (a porous polymer film that prevents short circuits), and anode are stacked alternately. The winding method rolls the three layers into a cylindrical or prismatic shape. The separator, made of materials like polyethylene (PE) or polypropylene (PP), must be thin yet strong enough to withstand electrolyte immersion and mechanical stress. The stacked or wound assembly is placed into a cell casing—cylindrical (e.g., 18650, 21700), prismatic (rectangular metal or plastic), or pouch (flexible aluminum-plastic laminate).
After assembly, the cell is filled with electrolyte, a lithium salt (e.g., LiPF6) dissolved in organic solvents (e.g., ethylene carbonate). The electrolyte facilitates ion movement between the electrodes. The filling is done in a dry room (dew point below -40°C) to prevent moisture, which reacts with the electrolyte to form harmful gases. The cell is then sealed—crimped for cylindrical cells, welded for prismatic metal casings, or heat-sealed for pouch cells.
Formation and aging follow. Formation involves charging and discharging the cell at low currents to activate the electrode materials and form a solid electrolyte interphase (SEI) layer on the anode, which stabilizes the cell and prevents further electrolyte decomposition. Aging stores the cells at elevated temperatures (40–60°C) for several days to identify early failures. Finally, the cells undergo testing for capacity, internal resistance, and safety, with defective units rejected. This rigorous process ensures that lithium battery cells meet performance and safety standards for use in various applications.
