Abstract

The present invention refers to a battery cell (100a) including an electrode assembly (110) having first and second electrode tabs (112, 113); a case (120a) accommodating the electrode assembly (111) therein and having a sealing portion (126a, 126b, 126c) formed at the edge of the case (120a); a protection element (140) connected to one of the electrode tabs (112, 113); and a mounting portion (130a, 130b, 130c) positioned in the sealing portion (126a, 126b, 126c) and accommodating the protection element (140) therein.

Description

[0001] This application claims priority to and benefit of U.S. Provisional Application No. 61 / 758,182, filed January 29, 2013 in the United States Patent and Trademark Office, which is hereby incorporated by reference in its entirety. technical field [0002] One aspect according to embodiments of the present invention relates to battery packs (eg, battery cells). Background technique [0003] Recently, various secondary batteries have been used as power sources for portable electronic devices. As portable electronic devices are used in various fields, demands for specific secondary batteries have rapidly increased. Secondary batteries can be charged / discharged many times and thus have economical and environmental efficiency. Therefore, the application of the secondary battery pack is promoted. [0004] As electronic devices become smaller and lighter, secondary batteries should also become smaller and lighter. However, since the secondary battery includes a material havi...
