Abstract
A stacking apparatus and a method for assembly of electrochemical cells. The stacking apparatus includes at least one stacking head having an adjustable holding member adapted to hold an electrochemical laminate of a pre-determined length and means for adjusting the shape of the electrochemical laminate of the pre-determined length during stacking of a plurality of electrochemical laminates. The electrochemical laminates are assembled in a way that prevents air entrapment between the electrochemical laminates.
Claims12
A stacking apparatus for assembly of electrochemical cells comprising:
- a supporting structure;
- at least one stacking head operative to stack a plurality of electrochemical laminates of a pre-determined length one on top of the other, said stacking head having at least one adjustable holding member adapted to hold a particular one of the electrochemical laminates and having means for adjusting the shape of the particular one of the electrochemical laminates, said at least one adjustable holding member being operative during stacking to hold the particular one of the electrochemical laminates in a shape such that a central portion of the particular one of the electrochemical laminates is deposited first and to subsequently move so as to progressively lower the remainder of the particular one of the electrochemical laminates, thereby preventing air entrapment between adjacent ones of the electrochemical laminates being stacked.
