SECONDARY BATTERY MANUFACTURING SYSTEM AND SECONDARY BATTERY MANUFACTURING METHOD

Embodiments provide a secondary battery manufacturing system. The secondary battery manufacturing system includes a controller configured to collect cell identifier (ID) sensing data, based on a cell ID sensing signal generated based on a data matrix read by a data matrix reader, in which the cell ID sensing data includes a cell ID that is a read value of the data matrix and a device number matching the cell ID, and the device number indicates a site where the data matrix reader is installed.
