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.
