    摘要： A battery pack includes a non-aqueous electrolyte secondary battery, a rigid covering member, and a protection circuit board. The secondary battery includes a battery element and a flexible covering member formed of a first laminated film composed of a first heat-bonding layer, a first metal layer, and a first outer covering layer laminated successively. The flexible covering member is sealed along around the battery element while leaving electrode terminals of the positive and negative electrodes extended outside the battery element. The rigid covering member is formed of a second laminated film composed of a second heat-bonding layer, a second metal layer, and a second outer covering layer laminated successively. The flexible covering member and the rigid covering member are bonded with an adhesive strength equal to or higher than atmospheric pressure and with a peel strength equal to or lower than a breaking strength of the flexible covering member.

    摘要： A rechargeable battery wherein the detachment due to deformation of a resin member is prevented by strengthening the fixing force of the resin member connecting a bare cell with a protection circuit module.
    The rechargeable battery includes a bare cell provided with a cap plate; a protection circuit module; and a resin member, wherein the rechargeable battery further includes a reinforcing member composed of a support plate part connected to one side of the cap plate and provided with a rivet through-hole; a resin fixing part integrally formed with one end of the support plate part, and bent at a certain angle in the direction of the protection circuit module and protruded therefrom; and a rivet connecting part fixing the support plate part to the cap plate by perforating the rivet through-hole.
    Thereby, the resin member is prevented from being deformed by the external force as the fixing force is increased by the fixing reinforcing member, further preventing that the resin member from being detached out of the bare cell.
