Abstract: A cell fixing apparatus includes a first shell element, a second shell element, and a plurality of pressure-adding beams. The first shell element and the second shell element are relatively fixedly connected, the first shell element and the second shell element are disposed at intervals in a first direction, so that an accommodating cavity is provided between the first shell element and the second shell element, and the accommodating cavity is configured to accommodate the cell. The plurality of pressure-adding beams may be disposed on a surface of the first shell element that is away from the second shell element. The plurality of pressure-adding beams may include a first-type beam and a second-type beam. A size of the first-type beam in the first direction is greater than that of the second-type beam. The pressure-adding beams are used to limit deformation of the cell in the accommodating cavity.
