Battery stacking process is mainly used for pouch cell and Aluminum case battery.

The stacking process uses multi-pole pieces in parallel to make the internal resistance of the battery smaller and the charging efficiency higher; and the heat generated during the charge and discharge cycle is relatively small and more uniform, and the battery safety is higher.

In addition, the lamination process makes the internal space of the battery more fully utilized, and the      battery energy density is relatively larger. Therefore, the lamination process is favored by the intelligent manufacturing of lithium batteries
