Abstract: A cell includes a positive electrode plate, a negative electrode plate, and a separator. An insulating adhesive tape is attached to the positive electrode plate. A first adhesive-tape surface of the insulating adhesive tape is disposed on a same side as a first positive-electrode-plate surface of the positive electrode plate. The first positive-electrode-plate surface is arranged between the first adhesive-tape surface and the second adhesive-tape surface in the first direction. The second adhesive-tape surface is arranged between the first positive-electrode-plate surface and the second positive-electrode-plate surface in the first direction. The insulating adhesive tape extends from the first positive-electrode-plate end to the second positive-electrode-plate end in the second direction. A battery module, a battery pack, and a vehicle including same are also provided.

Abstract: A battery separator includes a separator body and an insulating adhesive tape attached thereto. The separator body includes a first separator surface and a second separator surface arranged opposite to each other in a second direction, and includes a first separator end and a second separator end arranged opposite to each other in a first direction. The insulating adhesive tape includes a first adhesive-tape surface and a second adhesive-tape surface arranged opposite to each other in the second direction, and a first adhesive-tape end and a second adhesive-tape end arranged opposite to each other in the first direction. The insulating adhesive tape is attached to the separator body in the first direction, and the first adhesive-tape surface is arranged at a position corresponding to the first separator surface. The insulating adhesive tape extends from the first separator end to the second separator end in the first direction.
