Abstract: This application relates to a battery module and a battery pack. The battery module includes a binding member and battery cell assemblies arranged along a horizontal direction, the battery cell assembly including an upper-layer battery cell and a lower-layer battery cell that are stacked along a vertical direction, the upper-layer battery cell and the lower-layer battery cell interconnected and forming a joint; and the binding member covering the joint, located between two adjacent battery cell assemblies, and fixed to the battery cell assemblies. The battery module includes a binding member and a plurality of battery cell assemblies, and the battery cell assembly includes upper-layer and a lower-layer battery cells stacked along a vertical direction. A joint is formed between the upper-layer and lower-layer battery cells and covered by the joint fixed to the battery cell assemblies, swelling of the upper-layer and lower-layer battery cells at the joint is reduced.
