In cell assembly, a separator and electrode are joined together during vacuum drying. The joined cell of cathode and anode is either wound, rolled, or stacked. Lead tabs are attached to the folded cells. The process is complete when the cells are filled with electrolytes, vacuum-sealed, and dried. Cognex offers gauging, 2D code reading, alignment, guidance, and inspection solutions to ensure that lithium-ion cells can meet high energy density and performance demands. Cylinder-, pouch-, and prismatic- or can-type cells manufactured with Cognex technology are well-suited to mobile energy storage applications, including as automotive batteries for electric vehicles.
