본 발명은 리튬 전지에 관한 것으로서, 특히 리튬 전지를 구성하는 집전체를 제조함에 있어 2줄의 금속 와이어를 X, Y 축으로 교차시켜 집전체를 제작함으로서 천공작업에 의한 첨단부에 의한 집전체의 내부 단락을 방지할 수 있도록 한 금속 와이어로 제작된 리튬 전지 집전체에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lithium battery. In particular, in manufacturing a current collector constituting a lithium battery, a current collector is fabricated by crossing two lines of metal wires on the X and Y axes to produce a current collector. The present invention relates to a lithium battery current collector made of a metal wire to prevent an internal short circuit.
무전기, 컴퓨터, 가전 제품 그리고 자료 백업 기능을 갖는 각종 전자 장비에는 전류 공급을 위해 리튬 전지가 사용되고 있다. 리튬 전지는 작은 크기를 갖지만장시간 동안 일정한 전류를 공급할 수 있기 때문에 많은 전자기기에 사용되고 있다.Lithium batteries are used for current supply in radios, computers, consumer electronics, and other electronic devices with data backup capabilities. Lithium batteries have a small size but are used in many electronic devices because they can supply a constant current for a long time.
리튬 전지를 제작할 경우에 사용되는 집전체는 도 1에 도시되어 있는 형태로 제조되는 것이 일반적이다. 상기한 형태의 집전체(1)는 금속 박판에 천공 작업을 통해서 홀(5)을 형성함으로서 제조된다.The current collector used when fabricating a lithium battery is generally manufactured in the form shown in FIG. 1. The current collector 1 of the above-described type is manufactured by forming a hole 5 in a thin metal plate through a drilling operation.
천공 작업에 의해 홀이 형성되기 때문에 홀의 형성시 절단 부분이 날카롭게 가공된다. 집전체 홀의 날카로운 부분에 의해 내부 단락이 형성되는 문제점이 있었다.Since the hole is formed by the drilling operation, the cut portion is sharply processed when the hole is formed. There is a problem that an internal short circuit is formed by the sharp portion of the current collector hole.
전지 내부에 단락이 발생할 경우에는 전지의 안정성이 저하되는 문제점이 있었다.When a short circuit occurs inside the battery, there is a problem that the stability of the battery is lowered.
본 발명은 상기한 문제점을 해결하기 위한 것으로서, 리튬 전지 내부의 집전체를 제조함에 있어 금속 와이어를 X, Y 축으로 직교시켜 제작하여 집전체의 홀 형성시 절단 부분이 형성되지 않도록 함으로서 후 전지의 내부 단락을 방지할 수 있도록 한 금속 와이어로 제작된 리튬 전지 집전체를 제공한다.The present invention is to solve the above problems, in the manufacture of the current collector inside the lithium battery by producing a metal wire orthogonal to the X, Y axis to prevent the formation of the cut portion when forming the hole of the current collector Provided is a lithium battery current collector made of a metal wire to prevent an internal short circuit.

도 2는 본 발명에 의한 리튬 전지 집전체의 일실시예의 형태를 나타내는 도면으로서, 본 발명금속 와이어로 제작된 리튬 전지 집전체는 도전성 금속 와이어를 X, Y축으로 교차시켜 형성되어 있음을 도시하고 있다.2 is a view showing an embodiment of a lithium battery current collector according to the present invention, showing that the lithium battery current collector made of the metal wire of the present invention is formed by crossing conductive metal wires along the X and Y axes. have.
이때 금속 와이어는 Ni, Ti, Cu, Fe, SUS304, SUS304L 과 같은 도전성 재질로 제작 형성되고, 사용되는 금속 와이어는 0.05mm ~ 0.2mm 의 지름을 갖는 것이 바람직하다.At this time, the metal wire is made of a conductive material such as Ni, Ti, Cu, Fe, SUS304, SUS304L, and the metal wire used preferably has a diameter of 0.05mm ~ 0.2mm.
도면을 참조하여 본 발명을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the drawings.
본 발명에 의한 집전체의 제작을 위해 Ni, Ti, Cu, Fe, SUS304, SUS304L 과 같은 도전성 재질의 금속제 와이어를 준비한다. 이때 사용되는 금속제 와이어는 0.05mm ~ 0.2mm 의 지름을 갖는다.For the production of the current collector according to the present invention, a metal wire made of a conductive material such as Ni, Ti, Cu, Fe, SUS304, and SUS304L is prepared. The metal wire used at this time has a diameter of 0.05mm ~ 0.2mm.
우선, 다수의 금속제 와이어를 X축 상으로 배열하여 X축 집전체(20)를 형성한다. 이때 X축 집전체(20)의 전체 폭은 리튬 전지의 전극폭과 같은 정도로 설정하는 것이 바람직하고, X축 집전체(20)를 구성하는 각각의 와이어는 0.5mm ~ 2.0mm 의 간격으로 배치된다.First, a plurality of metal wires are arranged on the X axis to form the X axis current collector 20. At this time, the overall width of the X-axis current collector 20 is preferably set to the same as the electrode width of the lithium battery, each wire constituting the X-axis current collector 20 is arranged at intervals of 0.5mm ~ 2.0mm. .
금속 와이어를 이용하여 X축 집전체(20)가 형성된 후, 다른 금속제 와이어를 이용하여 각각의 X축 집전체(20)와 수직으로 교차되도록 연결하여 Y축 집전체(30)가 형성되도록 한다. Y축 집전체를 형성할 때 사용하는 와이어의 지름과 배치 간격은 X축 집전체를 형성하는 경우와 동일하다.After the X-axis current collector 20 is formed using the metal wires, the Y-axis current collector 30 is formed by connecting the X-axis current collectors 20 perpendicularly to each other by using other metal wires. The diameter and the spacing of the wires used for forming the Y-axis current collector are the same as those for forming the X-axis current collector.
상기와 같은 방법으로 X축 집전체(20)와 Y축 집전체(30)가 교차 연결되면서 그물 형태의 집전체(10)가 완성된다.In the same manner as described above, the X-axis current collector 20 and the Y-axis current collector 30 are connected to each other to form a net current collector 10.
종래의 기술에 의한 집전체의 경우 천공 작업에 의해 형성된 홀의 절단면이 날카로워 단락 현상이 발생하는 문제점이 있으나, 본 발명에 의한 집전체는 금속 와이어가 서로 교차하면서 형성된다. X축 집전체와 Y축 집전체의 교차에 의해 형성되는 그물눈 형태는 천공 작업에 의해 형성되는 것이 아니기 때문에 절단면이 형성되지 않아 단락 현상의 발생이 없다.In the case of the current collector according to the prior art, there is a problem that a short circuit occurs due to the sharp cut surface of the hole formed by the drilling operation, but the current collector according to the present invention is formed while the metal wires cross each other. Since the mesh shape formed by the intersection of the X-axis current collector and the Y-axis current collector is not formed by a punching operation, a cut surface is not formed and there is no short circuit phenomenon.
상기와 같이 구성된 본 발명에 의하면, 리튬 전지의 집전체를 형성함에 있어 금속 박판이 아닌 도전성 금속 와이어를 X, Y 축으로 교차 연결하여 제작함으로서 박판의 천공 작업시 발생하는 절단면의 단부 형상에 의한 단락 발생을 제거하는 효과를 갖는다.According to the present invention configured as described above, in forming the current collector of the lithium battery by short-circuit due to the end shape of the cut surface generated during the drilling operation of the thin plate by cross-linking the conductive metal wire, not the metal sheet, by the X, Y axis Has the effect of eliminating the occurrence.
