Abstract: A battery pack includes an electrode assembly, a lower case and an upper case. The electrode assembly has first and second electrode tabs. The lower case has an opening, and accommodates the electrode assembly so that the first and second electrode tabs face the opening. The upper case includes a protective circuit module and a molding portion integrally injection-molded with the protective circuit module, and seals the opening. In the battery pack, the protective circuit module has first and second terminals directly connected to the respective first and second electrode tabs.

Abstract: Disclosed is a rechargeable battery pack which can reduce the number of parts and simplify the assembly process. The rechargeable battery pack includes an electrode assembly performing charging and discharging operations, a protection circuit module insulation assembly, and a case accommodating the electrode assembly and bonded to the protection circuit module insulation assembly, the protection circuit module insulation assembly further including an electrolyte injection opening formed by penetration and a sealing plug sealing the electrolyte injection opening.

Abstract: A rechargeable battery that includes an electrode assembly, a case having an inner space and receiving the electrode assembly, and a protective circuit module mounted with a protective element controlling charge and discharge of the electrode assembly, wherein the protective circuit module includes a circuit board installed with the protective element and a metal part fixed to the circuit board and combined to the case.

Abstract: A high-capacity battery pack attachable to a small-sized electronic device in which a lithium-polymer cell and a lithium-ion cell are physically coupled and to be electrically connected in parallel, and an electronic device using the battery pack maximize a battery mounting space while providing a high-capacity battery pack useful for the small-sized electronic device. The battery pack is arranged such that the lithium-polymer cell having a thin thickness in a large cross-sectional area and a lithium-ion cell having a thick thickness in a small cross-sectional area are appropriately arranged to maximize the space of the battery accommodating portion.
