Cell pack and method for producing and method for disassembling the same

A method for producing a cell pack, comprising:

• arranging a plurality of unit cells in an arrangement direction, disposing a first sliding plate at an end portion of the plurality of unit cells in a first direction of the arrangement direction, and disposing a second sliding portion at an end portion of the plurality of unit cells in a second direction of the arrangement direction to prepare a second cell stack;
• compressing the second cell stack in the arrangement direction so that a dimension thereof in the arrangement direction becomes a first dimension;
• preparing a restraint mechanism which includes a first end plate portion, a second end plate portion, and a ring-shaped restraining hoop portion and in which the first end plate portion and the second end plate portion are disposed opposite each other and spaced apart by a first dimension along the arrangement direction and, in a plane parallel to the arrangement direction, the restraining hoop portion is disposed so as to surround the first end plate portion and the second end plate portion along the outer periphery thereof;
• installing an expansion suppressing jig that prevents a separation distance between the first end plate portion and the second end plate portion from spreading beyond the first dimension;
• inserting the compressed second cell stack between the first end plate portion and the second end plate portion;
• and
• restraining the plurality of unit cells while displacing the expansion suppressing jig in a direction in which the separation distance in the arrangement direction is increased and applying a load with the restraining mechanism to the plurality of unit cells in a direction of compressing along the arrangement direction.
