Abstract

A battery module and an electronic device are provided. The battery module includes a case and a cell. Multiple cells are stacked in the case along a thickness direction. The case includes a base plate, an upper cover, and a side wall. The side wall is formed by enclosing multiple side plates. The side plates include at least one movable plate capable of sliding along a stacking direction of the cells. When the cell swells, an swelling force and an swelling amount of the cell pushes the outermost cell to move toward the stacking direction, so that the movable plate is pushed and slides along with the swelling of the cell, which can reduce the swelling force on the movable plate to effectively reduce the swelling force on the movable plate in an swelling direction of the cell, so as to significantly improve the safety of the battery module.
