Battery manufacturing technicians prepare for and conduct processes in one stage of cell or battery manufacture. Electrode technicians produce the component that goes in battery cells. They perform processes such as mixing, coating, drying, calendering, and electrode slitting. Cell assembly technicians make individual cells performing processes such as winding, stacking, filling, and sealing. Formation technicians perform formation, ageing and testing processes and final inspection of cells, ensuring cells are charged and working. Module and pack technicians combine individual cells to make battery modules and packs, and conduct end of line testing and cell finishing. In relation to the stage that they work in, technicians conduct quality assurance and maintain process records. Maintaining workplace health, safety and environment is also key. Technicians also support other activities including continuous improvement, inventory control, and maintenance.
