description The utility model provides a battery cell and a battery pack, and belongs to the technical field of battery cell tab welding. The tab is electrically connected with the pole group, the tab comprises a base part and a folding part which are connected with each other, a crease is formed at the joint of the base part and the folding part, the folding part is connected with the base part in an attached manner after being folded at the crease, and the crease is connected with the upper end of the tab. According to the battery cell provided by the utility model, the folding part is folded and attached to the base part, and the width of the tabs is reduced while the overcurrent area and overcurrent capacity of the tabs are ensured by folding the tabs, so that the width of the welding plate can be reduced, the overall weight and cost of the top cover are reduced, and the layout of other structural parts on the cover plate is more convenient. 本实用新型提供一种电芯及电池包，属于电芯极耳焊接技术领域，其中，电芯包括：极组；极耳，与所述极组电连接，所述极耳包括连接设置的基部和折叠部，所述基部和所
