Problems solved by technology

If the electrode assembly is manufactured from misaligned battery cells, the electrode assembly may not be received in the battery case
Moreover, electrode assemblies fabricated from misaligned battery cells have the disadvantages of low energy density and less energy efficiency
[0008] In this case, there is no in-depth study on the technique of aligning the battery cells to make a stacked electrode assembly

Abstract

The present invention provides a battery cell stacking jig capable of rapidly stacking battery cells and improving the degree of alignment of the stacked battery cells. A battery cell stacking jig according to the present invention is configured to stack at least two battery cells and comprises: a seating portion for providing a space in which the battery cells are seated; and a battery cell alignment portion having a first block, which is mounted on the seating portion, and a second block, which is mounted on the seating portion and is arranged to be spaced apart from the first block by a predetermined distance, at least one of the first block and the second block being mounted on the seating portion to be able to move on the seating portion.

Description

technical field [0001] The present disclosure relates to a technique for manufacturing an electrode assembly, and more particularly, to a battery cell stacking jig for manufacturing a stacked type electrode assembly. [0002] This application claims Korean Patent Application No. 10-2013-0131745 filed in Korea on Oct. 31, 2013, Korean Patent Application No. 10-2013-0131746 filed in Korea on Oct. 31, 2013, and Priority of Korean Patent Application No. 10-2013-0131747 filed in Korea on Oct. 31, the disclosure of which is incorporated herein by reference. Background technique [0003] In general, secondary batteries are rechargeable and have a wide range of applications, as opposed to disposable primary batteries, for example, electronic equipment including mobile phones, laptop computers and camcorders, or electric vehicles. In particular, a lithium secondary battery has a larger capacity than a nickel-cadmium battery or a nickel-hydrogen battery, and thus is widely used as a ...
