Claim 19:
20. A method for producing a battery, comprising:
providing a battery module, the battery module comprises a battery cell arrangement structure and an end plate, the battery cell arrangement structure comprises a plurality of battery cells stacked upon each other, and the end plate is fixedly connected to the battery cell arrangement structure;
providing a box body, the box body comprises a first wall and a second wall, the second wall is connected to the first wall and extends upward, the second wall is provided with a restraint surface, and the restraint surface is configured to abut against the end plate to restrict the end plate from moving upward; and
putting the battery module into the box body and placing the battery module on the first wall, so that the end plate is located between the second wall and the battery cell arrangement structure, and the end plate is capable of moving towards the second wall when the battery cell arrangement structure expands, to provide expansion space for the battery cell arrangement structure;
providing a restraint protrusion on the end plate and an upper surface of the restraint protrusion is configured to abut against the restraint surface to restrict the end plate from moving upward;
setting a gap between the upper surface of the restraint protrusion and the restraint surface in an up and down direction and the restraint protrusion is located below the restraint surface when the battery cell arrangement structure is not expanded.
