From raw materials such as graphite, lithium cobalt oxide, copper foil, aluminum foil, ceramic diaphragm, aluminum shell, etc., to a complete battery, a total of 36 steps are required to go through 4 major processes. Among them, there will be a high temperature aging time of 1-3 days after injection, volumetric formation, and PACK to ensure the overall performance of the battery is stable. Before shipping and packaging, it will cooperate with the MES system for full inspection. The full inspection items include appearance, coding, electronic components, battery voltage, capacity, internal resistance and other details. Serve every customer with 0PPM quality control!
