Abstract

The invention provides a battery cell. The battery cell comprises a body part, a tab and a protective sleeve, and the body part includes a first end part. And the tab extends out of the body part from the first end part. The protective sleeve comprises a first part and a second part, the first end part is sleeved with the first part in a surrounding manner, and the second part extends out of the body part and surrounds the tab. And a bonding piece is arranged between the second part and the first end part and between the second part and the tab. The head of the battery cell is sleeved with the protective sleeve, and the protective sleeve can reduce the risk that the battery cell is likely to be broken in the scenes of falling, vibration, impact, extrusion or expansion and the like and the risk that the battery cell is likely to be abraded, scraped and broken in the processes of manufacturing, assembling, transporting, storing and the like. And the protective sleeve can be matched with the battery cell and is used for accommodating a bonding piece during glue filling of the battery cell, so that the glue filling efficiency and the operation convenience of the battery cell are improved. The invention also provides an electrochemical device and an electric device using the battery cell.
