    Abstract: A cylindrical battery includes a housing having an accommodating space; and a negative electrode sheet, a first separator, a positive electrode sheet, and a second separator that are wound multiple turns forming an electrode core. The housing is co-axial with the electrode core that is disposed in the accommodating space. The positive electrode sheet includes a positive electrode material layer and a positive electrode foil layer. The negative electrode sheet includes a negative electrode material layer and a negative electrode foil layer. Some of the wound turns of the positive electrode foil layer extends toward an end of the housing to form a positive electrode tab. Some of the wound turns of the negative electrode foil layer extends toward another end of the housing to form the negative electrode tab.

    Abstract: A battery cover plate assembly, a cell, battery module, a power battery, and an electric vehicle are provided. The battery cover plate assembly includes a cover plate, an inner electrode terminal, and an outer electrode terminal. The inner electrode terminal and the outer electrode terminal are electrically connected by using a current interrupt device. The current interrupt device includes a score member and a flipping member. The flipping member is electrically connected to the score member. In addition, the flipping member can act under an effect of air pressure to break a score on the score member. The flipping member forms an elongated structure extending along the cover plate.
