The general lamination mode in the prior art is lamination in a way that a lamination table moves back and forth, namely, after a negative electrode is laminated, the lamination table moves to a positive electrode for lamination, and a diaphragm forms a Z shape to separate the positive electrode plate from the negative electrode plate, so that the lamination speed is low, the production efficiency is low, and the development of a laminated battery is severely restricted.
