Electrode Manufacturing Raw materials are combined to produce a slurry material; this is coated onto a metallic substrate producing. Individual Anode & Cathode electrodes. The anode & cathode materials must be kept separate, at all times in order to prevent contamination. Cell Assembly (Cylindrical/Pouch) The Electrodes are brought together but separated by a ‘Separator’. The electrolyte solution is injected into the cell. Formation, Aging & Testing During the formation process, the cell receives it first electrical charge. A process of charging & discharging forms a protective layer on the electrodes. This protects the active material from the electrolyte solution. Module Assembly Individual cells are mechanically connected to form the battery module.
EV battery manufacturing processes are complex, sensitive, and delicate, in a multi-stage sequence with mixing, pumping, coating, injection, calendering, ageing and assembly operations. EV battery contaminants include moisture, particles and static, as well as chemical and electrical fire and safety risks. Therefore, robotics and automation are extensively used along with mini environment, to provide both product component protection and personnel safety. Typically, there are 4 processes to EV battery manufacturing. The following process steps are indicative of a typical battery, chemistries, and technologies. These process steps are carried out in multiple and different interconnected dry cleanrooms and storage areas, within the overall EV battery manufacturing facility
