Abstract

The invention provides a method of manufacturing a pouch type battery cell. In the method, the battery cell is aged, and furthermore air exhausting is performed on the battery cell in a state that the battery cell is kept in an aging direction. Therefore, the direction of the battery cell in the aging step does not change in the air exhausting step, and electrolyte does not disperse in the air exhausting step.

Description

technical field [0001] Aspects of the present invention relate to a method of manufacturing a pouch-type battery cell. Background technique [0002] Recently, battery cells have been variously used as power sources of portable electronic devices. As portable electronic devices are used in various fields, demands for battery units are rapidly increasing. The battery cell can be charged / discharged many times, and thus is economically and environmentally efficient. Therefore, the use of battery cells is encouraged. [0003] As small size and light weight of electronic devices are required, small size and light weight of battery cells are also required. According to such demands, pouch-type battery cells capable of being reduced in size and light in weight have recently appeared. However, since a material having high reactivity such as lithium is provided inside the pouch type battery cell, the safety of the battery cell is important. [0004] In addition, it is important t...
