Zusammenfassung:	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 collapsible pores. The collapsible pores are disposed in the body. The collapsible pores include at least a first pore and a second pore. A collapsing pressure of the first pore is less than a collapsing pressure of the second pore, so that the battery cushion can release a compression space in a terraced manner under different extrusion 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.
