Abstract

The invention relates to the technical field of power battery manufacturing, and discloses a lamination process. The lamination process comprises the following steps: S1, heating and pressing a first unit strip; s2, cutting the first unit strip material to form a first unit sheet; s3, heating and pressing the second unit strip; s4, cutting the second unit strip material to form a second unit sheet; s5, sequentially stacking one second unit sheet and at least one first unit sheet from bottom to top to form a battery cell; and S7, laminating the battery cell. According to the invention, the heating effect is ensured, the temperature difference between the center and the outer side of the battery cell is reduced, a preheating process is not required to be set before the battery cell is laminated, the process steps are reduced, the production efficiency of the battery cell is improved, the energy consumption is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power battery manufacturing, in particular to a stacking process. Background technique [0002] Laminated lithium batteries have been widely used in various fields. The assembly process of laminated cells generally consists of lamination, gluing, preheating, hot pressing, pre-welding, main welding and other processes. Among them, the role of the preheating process is to heat the stacked cells to make the temperature uniform inside and outside the cells; the role of the hot pressing process is to press the electrodes of the cells and the diaphragm by means of high pressure and heating. , which is conducive to improving the performance of the battery cell. However, the current preheating and hot pressing process takes a long time, which has become a bottleneck restricting the efficiency of the entire laminated cell assembly process, and because the entire cell is preheated and hot pressed, the equipment si...
