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-determin ed 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 prevent s air entrapment between the electrochemical laminates.

Claims (14)

1. A stacking apparatus for a ~ ing:
-a supporting structu -at least one stack ~ ng member adapted to hold an ~ mined length and having means ~ ctrochemical laminate;
-said at least one stacking head being operative to stack a plurality of said electrochemical laminates of the pre-determined length one on top of the other, during stacking said adjustable holding member holding each particular electrochemical laminate of the pre-determined length in a shape such that a central portion of the particular electrochemical laminate of the pre-determined length is deposited first followed by a motion of said adjustable holding member that progressively lowers the remainder of the particular electrochemical laminate of the pre-determined length, thereby preventing air entrapment between adjacent electrochemical laminates of the pre-determined length in the stack.
2. A stacking apparatus as defined in claim 1, wherein said adjustable holding member includes a vacuum system generating a negative pressure that holds said pre-determined length of electrochemical laminate.
3. A stacking apparatus as defined in claim 2, wherein said adjustable holding member includes a plate made of a micro-porous material through which the vacuum system generates said negative pressure.
4. A stacking apparatus as defined in claim 3, wherein said adjustable holding member includes a vacuum chamber positioned adjacent said plate of micro-porous material.
5. A stacking apparatus as defined in claim 1, further comprising mechanical cutting means adjacent said stacking head and adapted to cut a continuous length of electrochemical laminate to said pre-determined length.
6. A stacking apparatus as defined in claim 5, wherein said mechanical cutting means includes a rotary knife.
7. A stacking apparatus as defined in claim 1, wherein said at least one stacking head includes two adjustable holding members rotatably mounted onto said at least one stacking head.
8. A stacking apparatus as defined in claim 7, wherein said two adjustable holding members are rotatably mounted through a slot system guiding the rotational movement of said two adjustable holding members, thereby preventing damage to said electrochemical laminate of the pre-determined length.
9. A stacking apparatus as defined in claim 1, wherein said at least one stacking head is movable vertically and horizontally within said supporting structure.
10. A stacking apparatus as defined in claim 1, comprising a plurality of stacking heads mounted side by side on said supporting structure such that a plurality of electrochemical cells may be assembled simultaneously.
11. A stacking apparatus as defined in claim 1, further comprising a treated surface onto which a plurality of said electrochemical laminates of the pre-determined length are stacked.
12.A stacking apparatus as defined in claim 1, further comprising at feast one carriage platform having a' treated surface onto which a plurality of said electrochemical laminates of the pre-determined length are stacked.
13 13.A process for assembling a plurality of electrochemical laminates to form a battery comprising the steps of:
-laminating a continuous length of anode film with a continuous length of pre-assembled half cell comprising a current collector, a cathode film and an electrolyte separator film;
-cutting the laminate into pre-determined lengths of laminates;
-stacking said pre-determined lengths of laminates one on top of the other in a shape such that a central portion of each said pre-determined length of laminate is deposited first, followed by a motion that progressively lowers the remainder of said pre-determined length of laminate, thereby preventing air entrapment between adjacent pre-determined lengths of laminate in the stack.
14. A process for assembling a plurality of electrochemical laminates to form a battery wherein said electrochemical laminates are in a charged state when being assembled one above the other.
