Abstract

The present invention provides a battery case formed from a laminate sheet comprising an outer coating layer formed from a weather resistant polymer, an inner sealant layer formed from a thermosetting polymer, and a barrier layer interposed between the outer coating layer and the inner sealant layer, wherein an electrode assembly curvable or bendable in correspondence to the shape of a device, in which a battery cell is provided, is embedded, and a pattern is formed on at least one surface among surfaces facing the outer side of the electrode assembly.

Description

technical field [0001] The present invention relates to a battery casing with a wrinkle-resistant pattern. [0002] This application claims the benefit of Korean Patent Application No. 2014-0123643 filed with the Korean Intellectual Property Office on Sep. 17, 2014, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0003] With the remarkable development of information technology (IT), many kinds of portable information communication devices have been popularized. As a result, in the 21st century, we are moving towards a ubiquitous era in which high-quality information services are possible regardless of time and place. [0004] Lithium secondary batteries are very important in realizing such a ubiquitous era. In particular, lithium secondary batteries capable of charging and discharging have been widely used as energy sources for wireless mobile devices. In addition, secondary batteries have also been used as energy source...
