Description
본 발명의 전지의 양극단자와 연결되도록 하는 탭과의 접촉저항을 줄여 전지의 특성을 향상시키도록 한 이차전지의 양극판과 이의 제조방법에 관한 것이다.The present invention relates to a positive electrode plate of a secondary battery and a method of manufacturing the same, to improve the characteristics of the battery by reducing the contact resistance of the tab to be connected to the positive terminal of the battery of the present invention.
통상, 이차전지에 있어 전지의 음극단자는 극판이 삽입되는 캔 자체가 이루며, 양극단자는 캔에 결합되는 캡 어셈블리가 이루게 된다.In general, in a secondary battery, a negative electrode terminal of the battery is made of a can itself into which a pole plate is inserted, and a positive electrode terminal is formed of a cap assembly coupled to the can.
이에, 상기 캔에 삽입되는 전극부의 양극판과 음극판은, 상기한 양 단자에 각기 연결되어 각 단자를 통해 들어오는 전류를 전달받게 되는 바, 상기에서 양극판은 자신이 보유한 양극 탭을 상기 캡 어셈블리에 접속하고, 음극판은 캔에 부착됨으로써 각 단자의 연결되는 것이 일반적이다.Accordingly, the positive electrode plate and the negative electrode plate of the electrode part inserted into the can are connected to both terminals so as to receive current flowing through the respective terminals, wherein the positive electrode plate connects the positive electrode tab held therein to the cap assembly. The negative plate is generally connected to each terminal by being attached to the can.
이를 위해 종래의 이차전지 제조시에는, 양극판을 제조할 때, 양극판의 일부위에 상기한 양극 탭을 부착하게 되는데, 종래에 이루어지고 있던 이차전지의 양극판 제조는 개략 다음과 같은 공정을 거치고 있다.To this end, in the manufacture of a conventional secondary battery, the positive electrode tab is attached to a part of the positive electrode plate when the positive electrode plate is manufactured. The manufacturing of the positive electrode plate of the secondary battery, which is conventionally performed, is roughly as follows.
즉, ① Ni 집전체에 양극 활물질을 충진하고, ② 이를 건조하고 압연한 후, ③ 상기 집전체를 일정 크기에 맞추어 절단함으로써 양극판을 형성한다.That is, 1) a positive electrode active material is filled in a Ni current collector, ② dried and rolled, and ③ a positive electrode plate is formed by cutting the current collector to a certain size.
④ 그 다음으로는 상기 양극판에 양극 탭을 접속하기 위해, 상기 양극판의 일부위의 활물질을 제거하여 무지부를 형성하고, ⑤ 이 무지부에 소정의 크기를 갖는 양극 탭을 부착시킨다.(4) Then, in order to connect the positive electrode tab to the positive electrode plate, an active material on a part of the positive electrode plate is removed to form a non-coated portion, and (5) a positive electrode tab having a predetermined size is attached to the non-coated portion.
이러한 공정순을 통해 제조된 종래의 이차전지 양극판을 도면을 통해 더욱 알아보면, 도 4에 도시된 바와 같이 상기 양극판(1)이 상단 중심부에는 활물질이 제거되어 이루어진 무지부(10a)가 형성되어 있다.Referring to the conventional secondary battery positive electrode plate manufactured through the process in more detail through the drawings, as shown in Figure 4, the positive electrode plate 1 is formed on the top center of the solid portion 10a is formed by removing the active material.
이 무지부(10a)에는 전술한 바와 같이 상기 양극 탭(12a)이 부착되게 되는 바, 이때 이 양극 탭(12a)은 도 5를 통해 더욱 알 수 있듯이 상기 양극판(1)의 일면에 부착되게 된다.The positive electrode tab 12a is attached to the uncoated portion 10a as described above. At this time, the positive electrode tab 12a is attached to one surface of the positive electrode plate 1 as shown in FIG. 5. .
여기서 상기 양극 탭(12a)의 부착은 대개 용접을 통해 이루어지게 된다.The attachment of the positive electrode tab 12a is usually made by welding.
그런데, 상기한 종래의 이차전지 양극판은 다음의 문제점을 안고 있는 실정이다.However, the conventional secondary battery positive electrode plate has the following problems.
즉, 첫 번째 문제점으로는, 상기 양극 탭이 상기 무지부로부터 탈락되는 경우가 있어 전지의 잦은 불량이 초래된다는 것인데, 이러한 문제점은, 상기 양극 탭이 상기 양극판의 일면으로만 부착되어 있기 때문에 경우에 따라 그 지지력이 약화되는 것에서 기인하고 있다.That is, the first problem is that the positive electrode tab may be dropped from the uncoated portion, resulting in frequent defects of the battery. This problem is caused when the positive electrode tab is attached only to one surface of the positive electrode plate. As a result, the bearing capacity is weakened.
또한, 다른 문제점으로는 상기 양극판과 양극 탭 사이의 접촉저항이 증가되어 전지의 특성이 저하된다는 점이다.In addition, another problem is that the contact resistance between the positive electrode plate and the positive electrode tab is increased, thereby deteriorating the characteristics of the battery.
즉, 상기 양극판의 일면으로 부착되는 양극 탭은, 용량이 작은 전지에서는 접촉저항에 대해 그다지 문제를 일으키지 않으나, 용량이 큰 전지에 적용된 경우에는 커진 전류의 값을 감당하지 못해 결국 접촉저항을 증대시키게 된다.That is, the positive electrode tab attached to one surface of the positive electrode plate does not cause a problem about contact resistance in a battery having a small capacity, but when applied to a battery having a large capacity, the positive electrode tab cannot increase the value of the increased current and eventually increase the contact resistance. do.
따라서, 본 발명은 이와 같은 문제점들을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 양극 탭과 양극판과의 접촉면적 증대로 접촉 저항을 감소시켜 전동성의 향상으로 전지 특성을 좋게 할 수 있음은 물론, 양극 탭의 잦은 탈락현상을 막아 전지 불량율을 감소시킬 수 있도록 한 이차전지의 양극판과 이의 제조방법을 제공함에 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to improve the battery characteristics by reducing the contact resistance by increasing the contact area between the positive electrode tab and the positive electrode plate, of course, The present invention provides a cathode plate of a secondary battery and a method of manufacturing the same, which prevents frequent dropout of the cathode tab to reduce battery failure rate.
이에, 상기 목적을 실현하기 위하여 본 발명은, 활물질이 도포된 집전체의 일부위에 활물질이 제거된 무지부를 형성하고, 이 무지부에는 전지의 양극단자와 접속하기 위한 양극 탭을 부착하고 있는 이차전지의 양극판에 있어서, 상기 양극탭이 상기 무지부의 양면 모두에 걸쳐 부착 형성된 이차전지의 양극판을 제안한다.Accordingly, in order to realize the above object, the present invention provides a secondary battery in which a non-active material from which an active material is removed is formed on a portion of a current collector to which an active material is applied, and a positive electrode tab is connected to the positive electrode terminal of the battery.

또한, 본 발명은 상기 목적을 실현하기 위하여, 활물질이 도포된 집전체의 일부위에 활물질이 제거된 무지부를 형성하고, 이 무지부에는 전지의 양극단자와 접속하기 위한 양극 탭을 부착하고 있는 이차전지의 양극판 제조방법에 있어서, 상기 무지부 상에 슬릿부를 형성하는 단계와; 상기 슬릿부에 소정의 길이를 갖는 양극 탭을 삽입하는 단계와; 삽입된 상기 양극 탭을 절곡하여 상기 무지부의 양면에 상기 양극 탭을 밀착시키는 단계와; 상기 부지부에 밀착된 상기 양극 탭 부위를 용접 처리하는 단계가 포함된 이차전지의 제조방법을 제안한다.Further, in order to realize the above object, the present invention forms a non-coated portion from which an active material is removed on a part of a current collector coated with an active material, and the non-coated portion has a secondary battery attached with a positive electrode tab for connecting to the positive electrode terminal of the battery.

도 1은 본 발명에 따른 이차전지의 양극판을 도시한 정면도이고, 도 2는 도 1 B-B선의 단면도이다.1 is a front view illustrating a positive electrode plate of a secondary battery according to the present invention, and FIG. 2 is a cross-sectional view taken along line BB of FIG. 1.
도시된 바와 같이 상기 양극판(30)은 통상의 이차전지 양극판과 마찬가지로 집전체(Ni foam)(31a)의 내부에 양극 활물질(30b)을 충진하고, 그 중앙 상측부에는 양극 탭(30c)을 부착하여 형성되고 있다.As shown in the drawing, the positive electrode plate 30 is filled with a positive electrode active material 30b inside a current collector (Ni foam) 31a, and a positive electrode tab 30c is attached to an upper portion of the center thereof, similar to a conventional secondary battery positive electrode plate. Is formed.
상기에서 양극 탭(30c)은, 양극 활물질(30b)이 제거된 집전체(31a) 부위인 이른바 무지부(30d)에 부착되고 있는 바, 이 때 상기 양극 탭(30c)은 본 발명에 따라 상기 무지부(30d)에 양면 모두에 밀착된 형태를 유지하게 된다.In the above, the positive electrode tab 30c is attached to the so-called uncoated portion 30d, which is a portion of the current collector 31a from which the positive electrode active material 30b has been removed. In this case, the positive electrode tab 30c is in accordance with the present invention. The non-coated portion 30d maintains its shape in close contact with both sides.
이처럼 본 발명에서 상기와 같은 상태로 양극 탭(30c)를 부착하게 됨은, 이 양극 탭(30c), 이 양극 탭(30c)을 상기 무지부(30d) 양면에 부착시킴으로써, 그 지지상태가 강화되도록 하고 아울러, 상기 집전체(30a)와의 접촉면적이 증대되도록 하여 접촉저항을 줄이고자 함인데, 이러한 목적은 갖는 상기 양극 탭(30c)의 부착방법은 다음과 같이 이루어지게 된다.As described above, in the present invention, the positive electrode tab 30c is attached to the positive electrode tab 30c by attaching the positive electrode tab 30c and the positive electrode tab 30c to both surfaces of the uncoated portion 30d so that the supporting state thereof is strengthened. In addition, to reduce the contact resistance by increasing the contact area with the current collector (30a), the method of attaching the positive electrode tab (30c) having this purpose is made as follows.
도 3은 본 발명에 따른 상기 양극판(30)의 제조방법을 설명하기 위해 도시한 도면으로서, 우선 양극판(30)은 상기 집전체(30a)에 양극 활물질(30b)을 충진하고 이를 건조한 후 압연하여 일정 크기로 절단되어진다.3 is a view illustrating a method of manufacturing the positive electrode plate 30 according to the present invention. First, the positive electrode plate 30 is filled with the positive electrode active material 30b in the current collector 30a and dried and rolled. It is cut to a certain size.
그 다음으로는 일정부위-상측 중앙부-에 상기한 무지부(30d)을 형성하게 되는 바, 이 때, 이 무지부(30d)는 통상적인 초음파 활물질 제거기를 통해 형성된다.(S1)Then, the above-described plain portion 30d is formed at a predetermined portion-the upper center portion, and at this time, the plain portion 30d is formed through a conventional ultrasonic active material remover.
상기 무지부(30d)이 형성이 끝나게 되면, 그 다음으로는 상기 무지부(30d)상에 상기 양측 탭(30c)의 폭을 고려하여 슬릿브(30e)를 형성하게 된다.(S2)When the plain portion 30d is formed, a slit 30e is formed next on the plain portion 30d in consideration of the widths of the both side tabs 30c. (S2)
여기서 상기 슬릿부(30e)는 상기 양측 탭(30c)이 상기 무지부(30d)에 삽입 결합하기 위해 마련된 구멍부로서, 상기 양측 탭(30c)이 이 슬릿부(30e)에 삽입될 때의 초기형태는, 도면을 통해 알 수 있듯이 일자 형태를 취한다.(S3)Here, the slit portion 30e is a hole portion provided for inserting and coupling the both side tabs 30c to the plain portion 30d, and the initial stage when the both side tabs 30c are inserted into the slit portion 30e. The shape, as shown in the drawing, takes the form of a date. (S3)
이에, 상기 슬릿부(30e)로 상기 양측 탭(30c)이 삽입되면, 이 양측 탭(30c)은 상기 무지부(30d)를 중심으로 각기 절곡되어 상기 무지부(30d)이 양면에 밀착되게 된다.(S4)Accordingly, when the both side tabs 30c are inserted into the slit portion 30e, the both side tabs 30c are bent with respect to the plain portion 30d, respectively, so that the plain portion 30d is in close contact with both surfaces. (S4)
물론, 이 때, 상기 양측 탭(30c)의 일측부는 전지의 양극단자와 접속될 수 있기 위한 길이를 갖도록 절곡되어야 한다.Of course, at this time, one side of the both side tab (30c) should be bent to have a length that can be connected to the positive terminal of the battery.
이에, 상기와 같이 양측 탭(30c)이 상기 무지부(30d)에 결합되면, 용접기(50)를 통해 상기 양측 탭(30c)의 양면이 용접처리되어지는 바, 이에 따라 상기 양측 탭(30c)은 상기 무지부(30d)에 고정되게 된다.Thus, when both side tabs 30c are coupled to the plain portion 30d as described above, both sides of the both side tabs 30c are welded through the welding machine 50, and thus the both side tabs 30c are welded. Is fixed to the uncoated portion 30d.
이상과 같은 공정을 통해 상기 양측 탭(30c)의 상기 무지부(30d)에 부착되면, 상기 양극판(30)은 양측 탭(30c)을 종래의 양측 탭에 비해 상기 무지부(30d)에 접촉면적을 증대시키면서 부착시킬 수 있게 됨은 물론, 상기 무지부(30d) 양면으로 상기 탭(30c)의 양면을 용접결합시키는 관계에 따라 그 지지력 또한 강화시킬 수 있게 된다.When attached to the non-coating portion 30d of the both side tabs 30c through the above process, the positive electrode plate 30 contacts the both side tabs 30c with the non-coating portion 30d compared to the conventional both side tabs. In addition to being able to attach while increasing, the bearing force can also be strengthened according to the relationship of welding both sides of the tab 30c to both sides of the plain portion 30d.
상기한 실시예이 설명을 통해 알아본 바와 같이, 본 발명에 의한 양극판은 양측 탭이 무지부에 접촉되는 면적이 증대됨에 따라 이에 그에 따른 접촉저항을 줄어 들 수 있게 된다.As described above through the description of the embodiment, the positive electrode plate according to the present invention can reduce the contact resistance according to the increase in the area in which both tabs are in contact with the plain portion.
따라서, 본 발명이 적용된 이차전지는, 양측 탭의 접촉저항이 저하되어 양극판의 전도성 향상으로 전지 특성이 향상되는 이점을 지닐 수 있게 된다.Therefore, the secondary battery to which the present invention is applied can have the advantage that the contact resistance of both tabs is lowered, thereby improving battery characteristics by improving conductivity of the positive electrode plate.
더불어, 본 발명을 통해서는 양측 탭의 지지력 향상을 가져올 수 있게 되므로, 이에 양측 탭이 탈락되어 전지 불량이 초래되는 일은 미연에 방지할 수 있게 된다.In addition, through the present invention it is possible to bring the improved support of the both tabs, it is possible to prevent the two tabs from falling off to cause the battery failure in advance.
이러한 본 발명의 효과는 특히, 본 발명의 고용량의 전지에 적용될 경우 더욱 효과적으로 발휘될 수 있게 된다.Such effects of the present invention can be more effectively exhibited, especially when applied to the high capacity battery of the present invention.
