Are classified.
- a rectangular battery is manufactured by inserting some battery elements into a rectangular hollow case in which a lower end is sealed, welding a top cap assembly, injecting an electrolyte, and then sealing an injection hole.
- the rectangular hollow case with the lower end sealed is manufactured by the deep drawing processing method of the board
- the deep drawing processing method is a typical molding method for making a hollow container without a seam from a flat plate.
- the deep drawing processing method is a molding method in which a raw material plate 10 placed on the surface of the die 30 is pressed 21 with a punch 20 to be plastically processed.
- the deep drawing process has the advantage that the efficiency of the process is high because the final hollow case can be manufactured from a plate by a series of continuous processes, but has the following problems.
- the manufacturing cost of the apparatus for this is very high, and in particular, the manufacturing of a mold or the like generally takes a long period of 2 to 3 months. This significantly increases the time required to develop a battery that meets changing consumer tastes.
- the degree of stretching of the metal sheet each portion is different depending on the shape of the mold. In some cases, when the metal sheet is out of the allowable elongation range, a deterioration phenomenon may occur. Therefore, there exists a limit of the shape which can be processed by the deep drawing process.

It is to provide a rectangular battery cell that can be reduced.

- the rectangular cell case manufactured by the deep drawing process may cause a crack in the material during the process of drawing along with the drawing, thereby greatly reducing the strength, or breaking the air, causing a failure rate of the product.
- the weakened strength lowers the sealing force and is easily broken by external impact. This problem also makes it impossible to fabricate rectangular cell cases with constant depth and width.
- the battery cell according to the present invention does not occur at all as described above.
- the manner of coupling the case members may vary.
- the cell case may be manufactured by welding the interface with the case members in close contact with each other in the shape of the cell case so that the contact ends face each other.

Specifically, when the cell case is too thick, it is possible to increase the overall thickness or volume of the finished battery cell. On the other hand, if the cell case is too thin, it is impossible to impart the desired mechanical strength to the cell case, and the rectangular battery cell cannot be protected against external impact.
- the battery cell according to the present invention may be manufactured by accommodating a folding structure or an electrode assembly having a stack structure in a cell case, or by accommodating an electrode assembly having a stack / folding structure.
- the rectangular battery cell according to the present invention is not particularly limited as long as the electrode assembly is mounted in the battery case, but as a specific example, lithium having high energy density, discharge voltage, and output stability may be used. It may be a secondary battery.
