Abstract
The present application relates to a battery cell, a battery, and an electrical apparatus in the field of battery technologies. The battery cell includes a case assembly, an end cover, and an electrode assembly. The case assembly defines an accommodating cavity with an opening, and includes first and second electrode lead-out portions positioned at one end of the case opposite the opening along a first direction. The end cover seals the opening. The electrode assembly, positioned inside the cavity, includes a main body, a first tab, and a second tab of opposite polarity. Both tabs are arranged at one end of the main body away from the end cover and are electrically connected to the corresponding lead-out portions. The end cover includes a pressure relief portion configured to release internal pressure. This design facilitates the integration of pressure relief features and simplifies the structural arrangement of the battery cell.
