The battery cover plate assembly includes a cover plate, an inner lead-out member, and an outer electrode terminal. The inner lead-out member and the outer electrode terminal are electrically connected by using a current interrupt apparatus. A flipping member of the current interrupt apparatus is electrically connected to the outer electrode terminal. A score member is electrically connected to the inner lead-out member. A score is formed on the score member and is electrically connected to the flipping member. The inner lead-out member is mounted on the cover plate through a cover plate insulator. The cover plate insulator has a first engagement portion engaged with the cover plate and a second engagement portion engaged with the inner lead-out member.
