Description

  The present invention relates to a laminating apparatus for producing a laminated body such as an electrode plate used for an electricity storage device such as a lithium ion capacitor.

  Generally, an electricity storage device is formed by stacking positive and negative electrode plates coated with an active material on each other via a separator made of an insulating material. Further, in a lithium ion capacitor or the like, a metal lithium layer or the like is formed on a predetermined electrode plate. Such a metal lithium layer is formed, for example, by attaching a metal lithium foil to an electrode plate (see, for example, Patent Document 1).

  In Patent Document 1, a first roll that adsorbs and intermittently feeds a strip-shaped lithium foil, a processing mechanism that forms a perforation in the lithium foil on the first roll, and intermittently rotates in synchronization with the first roll. And a second roll that receives the lithium foil after perforation formation from the first roll, and a third roll that continuously rotates while sliding on the second roll, and the feed amount of the second roll and the third roll The configuration in which the lithium foil is cut along the perforation due to the difference and the cut lithium foil is pasted on the electrode plate at a predetermined interval is illustrated.

  However, in the configuration having a plurality of rolls as in Patent Document 1 and the like, there is a concern about an increase in the size of the apparatus. On the other hand, an apparatus or the like in which the functions of the plurality of rolls are integrated is also found (see, for example, Patent Document 2 and FIG. 10).
