Abstract
Embodiments of the present application provide a protective device for cell including a first conductive component and a second conductive component that are disposed oppositely and spaced apart. A switching unit disposed between the first conductive component and the second conductive component is configured to disconnect the first conductive component from the second conductive component based on a predetermined temperature of the cell. The purpose of the present application is to provide a protection device for cell to timely cut off the internal circuit of the cell when the internal temperature of the cell is high.
