Problems solved by technology

[0009] However, when this type of adhesive member is used for a long time, the adhesive components deteriorate, so the adhesive strength may decrease significantly
In addition, double-sided tape requires continuous management during processing because defects such as problems such as tape not conveyed or tape being stretched occur, and the unit price is high, which leads to a decrease in profit margins

Abstract

A battery cell assembly manufacturing method according to an embodiment of the present invention is a method for manufacturing a battery cell assembly comprising a plurality of battery cells stacked on each other, and the method comprises a step of joining adjoining battery cells among the plurality of battery cells to each other by using a one-component liquid material, wherein the one-component liquid material is applied onto the battery cells by a spray application method.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0056450 filed with the Korean Intellectual Property Office on May 14, 2019, the disclosure of which is incorporated herein by reference. [0003] The present invention relates to a battery cell assembly and a manufacturing method thereof, and more particularly, to a battery cell assembly and a manufacturing method thereof capable of reducing defects in processes and increasing profit margins. Background technique [0004] Secondary batteries, which are easily applied to various product groups and have electrical characteristics such as high energy density, are commonly used not only in portable devices but also in electric vehicles (EV) or hybrid vehicles (HEV), driven by electric drive sources energy storage system, etc. Since such a secondary battery has the main advantage of significantly reducing the use of fossil fuels an...
