    摘要： The present disclosure relates to composite battery covers including one or more integral vent members configured to release pressure. An example composite battery cover includes a continuous sheet having a first stiffness and one or more vent members defined in the continuous sheet. Each of the one or more vent members may include a first area having a second stiffness and/or a second area having a third stiffness. The second stiffness may be different from the first stiffness. The third stiffness may be different from the second stiffness and/or the first stiffness. The stiffness and strength of the continuous sheet and/or one or more vent members may be controlled by variable thicknesses and/or fiber loadings.

    摘要： The present application discloses an improved aluminum cover plate of a battery, including a cover plate, a metal sheet and an electrode column. The electrode column penetrates and is arranged in rivet holes of the cover plate and the metal sheet, and is riveted with the metal sheet. A first sealing ring is arranged between a cap portion and a nail portion of the electrode column and the cover plate. A second sealing ring is arranged on an outer periphery of the nail portion of the electrode column, and the second sealing ring is clamped and arranged between the cover plate and the metal sheet. The first sealing ring and the second sealing ring are arranged separately.
