Form lamination band.In laminating equipment, which is successively folded into Z-shaped knot at the position of every adjacent cathode pole piece
Structure, then anode pole piece is inserted into the gap of Z-shaped structure, then the lamination of the zigzag structure inserted with anode pole piece is with pressure
Conjunction forms lamination band.
Another lamination process is the setting polarity interval that same distance is spaced in the mode separation strapping of two-layer laminate setting
Pole piece, such as：Anode pole piece, cathode pole piece, anode pole piece ..., its shape is integral, then between adjacent pole piece
Heat-sealing, it is same to form Z-shaped structure, due in which, the polarity of pole piece be it is spaced, therefore, only need to be by the Z-shaped
Laminated cell can be made in the lamination band pressing of shape structure.
Certainly, the more than both the above mode of mode of laminated cell is formed, no longer enumerated here.
In conclusion in lamination band provided by the present embodiment, lamination band making apparatus and laminating equipment, lamination band packet
It includes：At least mode separation strapping of two-layer laminate setting, is provided with a row along mode separation strapping length direction array between adjacent two layers mode separation strapping
The pole piece of arrangement；Mode separation strapping and pole piece are compound integral, and are located on each layer mode separation strapping with the position arranged between adjacent pole piece
Equal heat-sealing.It in the lamination band, respectively arranges at the position between adjacent pole piece, the equal heat-sealing of diaphragm, so that postorder adds
In work, diaphragm do not separated, fold, is formed by the phenomenon that finished product battery core is less prone to short circuit, and then improve the qualification of product
Rate.
The foregoing is a further detailed description of the present application in conjunction with specific implementation manners, and it cannot be said that this Shen
Specific implementation please is only limited to these instructions.For those of ordinary skill in the art to which this application belongs, it is not taking off
Under the premise of from the present application design, a number of simple deductions or replacements can also be made.
