Abstract

The invention relates to a battery pack and a method of manufacturing same. The battery pack comprises a bare cell and a protection circuit module positioned on top of the cap plate of the bare cell and a cover. Threaded connectors are used to connect the cover to the bare cell. The threaded connectors are chemically polished to enhance the engagement between the connectors and the cap plate.

Description

[0001] This application claims the benefit of US Provisional Patent Application 61 / 310,193, filed March 3, 2010, entitled "Battery Pack and Method of Making Same," which is hereby incorporated by reference in its entirety. technical field [0002] One or more embodiments of the present invention relate to a battery pack and a method of manufacturing the same, and more particularly, to a battery pack including self-tapping screws and a method of manufacturing the battery pack. Background technique [0003] Recently, small and lightweight portable electric / electronic devices, such as cellular phones, notebook computers, camcorders, etc., are actively being developed and produced. Accordingly, the portable electric / electronic device includes a battery pack, so that the portable electronic device can be operated even in a location where no additional power source is available. Batteries generally use economical secondary batteries that can be charged and discharged. Typical sec...
