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 fixture, which can quickly stack battery cells and improve the alignment degree of the stacked battery cells. The battery cell stacking jig according to the present invention is configured to stack at least two battery cells, and includes: a seating portion for providing a space in which the battery cells are seated; and a battery cell aligning portion, the battery cell The body aligning part has a first block mounted on the seating part and a second block mounted on the seating part, the second block is arranged to be spaced apart from the first block by a predetermined distance, the first block and the second block At least one of the two blocks is installed on the placement part so as to be movable on the placement part.

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 ...
