Problems solved by technology

Therefore, the length of the sealing portion for folding the secondary battery pouch increases, so it is difficult to satisfy the quality required by customers using only the existing folding equipment
[0016] In addition, there is an increasing need to increase the number of sealing parts for folding to alleviate the problem of an increase in the size of the secondary battery pouch due to the increase in capacity, but it is also difficult to meet such requests from customers using only existing folding equipment

Abstract

The disclosed sealing portion forming apparatus for folding a secondary battery pouch comprises: first and second pressing bars that are disposed to face each other with a sealing portion for folding interposed therebetween so as to apply a pressing force for flattening the sealing portion for folding, the sealing portion being defined by the edges of the secondary battery pouch that seals an electrode assembly accommodated therein; first and second pressing surfaces provided respectively on the first and second pressing bars and disposed to face the sealing portion for folding; and a forming protrusion provided on the first pressing surface and forming a folding guide line in the sealing portion for folding by means of a pressing force from the first and second pressing bars.

Description

technical field [0001] The present disclosure relates to an apparatus for forming a sealing portion for folding a secondary battery pouch, in detail, an apparatus for forming a sealing portion for folding a secondary battery pouch capable of improving the secondary battery pouch. The folding quality of the seal of the pouch and prevents the seal from springing back after being folded. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Demand for secondary batteries as energy sources is rapidly increasing as technology develops and demands for mobile devices, electric vehicles, and energy storage systems (ESS) increase. Therefore, many studies on secondary batteries capable of satisfying various demands are being conducted. [0004] Typically, in terms of shape, small-sized prismatic secondary batteries that can be applied to products such as mobile phones and large-sized ...
