Abstract: The present application relates to a battery module. The battery module includes a battery group and an insulating plate. The battery group includes a bus bar and a plurality of battery units, each battery unit includes a tab which includes a connecting segment and a bending segment. The insulating plate includes a plurality of plate assemblies, and the adjacent plate assemblies are connected through a connecting plate. There is an obtuse angle between each plate assembly and the connecting plate connected thereto. Each connecting segment passes through a guiding groove, and the bending segment and the bus bar are fixed and connected. The guiding groove can adjust the altitude of the tab as it passes through the insulating plate. The bending segment can be connected to the bus bar, then the process requirements can be met with a small space, which improves the energy density of the battery module.

Abstract: A battery includes two battery cells arranged along a first direction and including two electrode terminals opposite to each other along the first direction. A first electrode of the two electrode terminals is disposed at an end of a first battery cell of the two battery cells along the first direction, and a second electrode of the two electrode terminals is disposed at an end of a second battery cell of the two battery cells along the first direction. Surface contact is formed between two end faces of the two electrode terminals, respectively. The two end faces are opposite to each other along the first direction. The two electrode terminals are configured to be fixedly connected to each other along an outer periphery of at least one of the two end faces to implement electrical connection between the two battery cells.

Abstract: The present disclosure provides a buffering member and a battery module, the buffering member comprises a first member and a second member. The first member comprises a first main body and a first connecting portion, the second member comprises a second main body and a second connecting portion. The first main body and the second main body face each other, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion. Because the first member and the second member are independent members, and they can be formed by separately cutting a sheet. Because the first member and the second member each are small in size and simple in structure, and they can be rapidly formed by using less material, the whole structure of the buffering member is simple and the buffering member uses less material, thereby maximally improving the utilization rate of the sheet.
