The battery assembly method first assembles a first cover plate module into the opening of the outer shell body, and bends the tabs opposite to the first cover plate module so that the tabs overlap the surface of the connecting piece located below the connecting window. Next, the outer shell body is sealed. Finally, the tabs and connecting pieces are welded using the connecting window to achieve current conduction between the tabs and the terminals. Thus, the step of connecting the tabs to the terminals through the connecting piece is placed after the step of sealing the outer shell body. On the one hand, this avoids the impact of vibration, high temperature and other adverse factors during the welding process on the already welded tabs and terminals when the outer shell body is sealed, thus improving the welding quality between the terminals and tabs. On the other hand, since the first cover plate module and the outer shell body are in a fixed state, the difficulty of welding the tabs and connecting pieces is reduced.
