Lithium Metal Battery Assembly

The Z-shaped lithium metal battery stacking machine is a pivotal piece of equipment in the mid-stage production process of lithium battery manufacturing. Lithium metal battery production can be broadly divided into four major processes: electrode sheet production, cell assembly, cell activation and testing, and module/Pack encapsulation. Among these, cell assembly constitutes the mid-stage production, encompassing processes such as winding or stacking, cell pre-encapsulation, and cell electrolyte injection. Stacking, in particular, involves arranging individual electrode sheets produced in the die-cutting process into a cell.

The Z-shaped stacking machine stands out in the market as one of the four main types of stacking equipment, alongside cut-and-stack machines, thermal bonding stacking machines, and winding-stacking integrated machines. Currently, the Z-shaped stacking machine is the most widely applied in China due to its efficiency and reliability.
