Abstract
This application discloses a battery cushion and a forming method thereof, and a battery module and a forming method thereof. The battery cushion includes a body and breakable bubbles. The breakable bubbles are disposed in the body. The breakable bubbles include at least a first bubble and a second bubble. A breaking pressure of the first bubble is less than a breaking pressure of the second bubble, so that the battery cushion can release a space occupied by the battery cushion in a progressive manner under different external forces. The battery cushion disclosed in this application can not only achieve a pre-tightening force required during assembly of the battery module but also effectively relieve an expansive force generated during working of the battery module.
