The invention discloses composite lamination equipment which comprises a first pole piece attaching device and a second composite device, and the second pole piece attaching device, a third composite device and a lamination device are sequentially arranged on the downstream of the first composite device. The first pole piece laminating device and the second compounding device are respectively used for laminating and compounding a second polar piece on the first side of the compound middle piece, and the second pole piece laminating device and the third compounding device are respectively used for laminating and compounding another second polar piece on the second side of the compound middle piece; the first pole piece laminating device and the second pole piece laminating device enable the distances between the two adjacent second pole pieces located on the first side and the second side to be equal; and the lamination device enables the composite middle sheets to be folded between the adjacent second polar sheets.
Description
technical field [0001] The invention relates to the technical field of lithium ion battery production and manufacturing, in particular to a composite lamination device and a composite lamination process. Background technique [0002] At present, in the production process of lithium batteries, there are two ways to assemble the pole pieces into cells, one is winding, and the other is lamination. Generally speaking, square batteries and cylindrical batteries are basically wound, while soft pack batteries are mainly laminated. However, with the development of lithium batteries, the size of the battery cells is also increasing, the optimal rate of the winding solution has begun to decrease, and the cost has increased. In order to reduce costs and improve yield, prismatic cells are now beginning to use stacking solutions. [0003] At present, the lithium battery industry has higher and higher requirements for battery performance and other aspects. In fact, it is also the improv...
