Cell Fabrication: The first step in battery production is to create the individual cells. This involves mixing and coating the necessary materials, such as lithium, nickel, and cobalt, onto a current collector. The coated current collector is then rolled up and inserted into a cylindrical or prismatic casing. Cell Testing and Sorting: Once the cells are fabricated, they undergo rigorous testing to ensure they meet the required standards. Cells that pass the tests are then sorted and grouped according to their performance characteristics. Module Assembly: The sorted cells are then assembled into modules, which are essentially groups of cells connected in series and parallel. The modules are designed to provide the necessary voltage and capacity for the battery pack. Pack Assembly: The final stage of battery production involves assembling the modules into a complete pack. This includes installing the necessary electrical connections, cooling systems, and management systems.
