Abstract

The invention discloses a lamination method for cell manufacturing and cell electrode group manufacturing equipment. The lamination method comprises the steps: a first diaphragm and a second diaphragm are oppositely arranged, positive electrode sheets are inserted between the first diaphragm and the second diaphragm one by one and staggered on one side of the first diaphragm facing away from the second diaphragm, and negative electrode sheets are arranged on one side of the second diaphragm facing away from the first diaphragm. According to the lamination method, the two diaphragms can be laminated simultaneously so that the manufacturing time of the cell electrode group is shortened, the manufacturing efficiency of the cell electrode group is improved and thus the manufacturing efficiency of the cell is improved.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular, to a lamination method for manufacturing electric cores and equipment for manufacturing electric core pole groups. Background technique [0002] In related technologies, with the development of new energy machinery such as new energy vehicles, the application of batteries is becoming more and more extensive. In the field of lithium batteries and other batteries, z-shaped lamination technology is usually used when manufacturing the electrode group of the battery cell, that is, when laminating, the negative electrode sheet is stacked first, then the negative electrode sheet is coated with a separator, and then the positive electrode sheet is stacked. Wrap the separator around the positive electrode. The lamination unit of this lamination method is a single pole piece or a single diaphragm, and the speed of using this lamination method is slow, resulting in low efficiency of cell...
