1. A clamping device for forming a battery, the clamping device comprising:
a first plate;
a second plate positionable relative to the first plate such that a space between the first plate and the second plate is sized to receive the battery;
a coupling member coupling the first plate to the second plate, wherein one or both of the first plate and the second plate is movable away from the other plate, the coupling member having a first end portion and a second end portion; and
an elastic member disposed between the first end portion and the second end portion, the elastic member forcing the first plate toward the second plate;
wherein, in use, the clamping device is configured to be removed after cell formation or cell pretreatment.
