본 발명은 전극군이 수납되는 캔 내부의 유효 공간을 확장하여 고용량화를 실현할 수 있도록 한 각형 이차전지에 관한 것이다.The present invention relates to a rectangular secondary battery capable of realizing high capacity by expanding an effective space inside a can in which an electrode group is accommodated.

이차전지는 재충전이 가능하고 소형 및 대용량화가 가능한 것으로, 대표적으로는 니켈수소(Ni-MH)전지, 리튬(Li)전지 및 리튬이온(Li-ion)전지가 사용되고 있다.Rechargeable batteries can be recharged, miniaturized, and large-capacity. Typically, nickel-hydrogen (Ni-MH) batteries, lithium (Li) batteries, and lithium-ion (Li-ion) batteries are used.

여기서 리튬이온전지는 정극 활물질로 리튬-금속산화물을 사용하고, 부극 활물질로 탄소 혹은 탄소복합체를 사용하며, 유기 용매에 리튬염을 녹인 액체 전해질을 함침하여, 정극과 부극의 사이에서 리튬 이온이 이동되어 충·방전이 이루어지도록 한다.Here, the lithium ion battery uses lithium-metal oxide as the positive electrode active material, uses carbon or a carbon composite material as the negative electrode active material, impregnates a liquid electrolyte in which lithium salt is dissolved in an organic solvent, and moves lithium ions between the positive electrode and the negative electrode. To be charged and discharged.

이러한 리튬이온전지는 외관상 원통형과 각형 전지로 구분되는 바, 그 중에서 각형 이차전지는 도 3에 도시한 바와 같이, 정극과 세퍼레이터 및 부극이 함께 권취된 전극군(2)을 상기 부극과 연결된 캔(4) 내부에 수납하고, 그 캔(4)의 상부에 상기 정극과 접속된 캡 어셈블리(6)를 설치하며, 그 캡 어셈블리(6)에 형성된 주입구(8)를 통해 액체 전해질을 주입한 후 밀봉하는 구조로 이루어진다. 전극군(2)은 상면과 하면에 각각 절연판(10a)(10b)을 설치하여 캡 어셈블리(6) 및 캔(4)과 절연된다.The lithium ion battery is divided into a cylindrical and a rectangular battery in appearance. Among them, as shown in FIG. 3, a lithium secondary battery may include an electrode group 2 in which a positive electrode, a separator, and a negative electrode are wound together. 4) It is housed inside, the cap assembly 6 connected to the positive electrode is installed on the top of the can 4, the liquid electrolyte is injected through the injection hole 8 formed in the cap assembly 6, and then sealed. It is made of a structure. The electrode group 2 is insulated from the cap assembly 6 and the can 4 by providing insulating plates 10a and 10b on the upper and lower surfaces, respectively.

캡 어셈블리(6)를 구성하는 것으로는 캔(4)의 상측 개구에 레이저 용접되는 부극 플레이트(12)가 있고, 그 부극 플레이트의 중심에 절연체(16)를 개재하여 정극 플레이트(14)가 설치되며, 부극 플레이트(12)와 정극 플레이트(14)의 중심을 관통하는 리벳(18)을 이용하여 한 몸체로 조립된다. 리벳(18)은 전극군(2)의 정극 탭(20)과 연결되고, 가스켓(22)을 개재하여 부극 플레이트(12)와 절연된다. 또, 부극 플레이트(12)에는 전지의 내압 상승에 대한 방폭수단으로 파단부(24)를 설치한다.The cap assembly 6 includes a negative electrode plate 12 which is laser-welded to an upper opening of the can 4, and a positive electrode plate 14 is installed in the center of the negative electrode plate via an insulator 16. Then, it is assembled into a body by using the rivets 18 penetrating the center of the negative electrode plate 12 and the positive electrode plate 14. The rivet 18 is connected to the positive electrode tab 20 of the electrode group 2 and insulated from the negative electrode plate 12 via the gasket 22. In addition, the negative electrode plate 12 is provided with a breaking portion 24 as an explosion-proof means for increasing the internal pressure of the battery.

이렇게 구성된 각형 이차전지에서, 종래에는 전극군(2)과 캡 어셈블리(6)를 절연하기 위해 상부 절연판(10a)을 구비하게 되는 바, 이것은 실제적으로 충·방전 반응을 일으키는 전극군(2)의 높이 즉, 캔(4) 내부의 유효(有效) 공간을 줄어들게 만드는 문제점이 있다.In the rectangular secondary battery configured as described above, the upper insulating plate 10a is conventionally provided to insulate the electrode group 2 and the cap assembly 6, which is a component of the electrode group 2 that actually causes the charge / discharge reaction. There is a problem of reducing the height, that is, the effective space inside the can 4.

또한 상기 절연판(10a)은 전해액 주입을 방해하여 제조 공정을 어렵게 만드는 문제점이 있다.In addition, the insulating plate 10a has a problem of making the manufacturing process difficult by preventing the electrolyte injection.

앞서 설명한 종래 기술의 문제점을 해소하기 위한 것으로서, 본 발명은 상부 절연판을 제거하여 전극군이 수납될 유효 공간을 확대하고 고용량화를 실현하는 것이며, 아울러 부품 수를 줄여 제조 공정을 용이하게 실현할 수 있도록 한 각형 이차전지를 제공함에 그 목적이 있다.In order to solve the problems of the prior art described above, the present invention is to remove the upper insulating plate to increase the effective space to accommodate the electrode group and to realize a high capacity, and to reduce the number of parts to facilitate the manufacturing process. Its purpose is to provide a rectangular secondary battery.

이를 위하여 본 발명에서는 캡 어셈블리를 구성하는 것으로 부극 플레이트의 중앙 부위에 절연체 및 가스켓을 개재하여 정극 플레이트를 적층하고, 이들을 리벳을 이용하여 어셈블리함에 있어서, 상기 가스켓을 전극군의 횡단면과 같은 크기로 형성하여 전극군의 상부 절연판 기능을 갖도록 하고, 그 일측에 적어도 하나의 통로를 형성하여 전해액 주입 통로로 사용하는 것을 특징으로 한다. To this end, in the present invention, the cap assembly is constituted by stacking the positive electrode plates in the center portion of the negative electrode plate through an insulator and a gasket, and assembling them using rivets. Thus, to have a function of the upper insulating plate of the electrode group, at least one passage is formed on one side thereof to be used as the electrolyte injection passage.                         

또 상기 가스켓에는 파단부 통로를 형성할 수 있다.In addition, a break passage may be formed in the gasket.

이에 따라 본 발명의 각형 이차전지는 실제 충·방전 반응에 기여하는 전극군의 용량을 증대할 수 있는 것이며, 부품 수의 감소로 제조 공정을 용이하게 실현할 수 있게 된다.
Accordingly, the rectangular secondary battery of the present invention can increase the capacity of the electrode group contributing to the actual charge / discharge reaction, and the manufacturing process can be easily realized by reducing the number of parts.

이하, 본 발명의 바람직한 실시예를 첨부 도면에 의거하여 보다 상세하게 설명한다. 참고로 본 발명의 구성을 설명함에 있어 종래 기술에서 설명한 도면과 동일한 부분에 대하여는 동일 부호를 부여하기로 한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described in detail based on an accompanying drawing. For reference, in the description of the configuration of the present invention will be given the same reference numerals for the same parts as the drawings described in the prior art.

도 1은 본 발명에 의한 각형 이차전지를 분리 도시한 것이고, 도 2는 본 발명의 내부 구성을 보여주고 있다.1 illustrates a rectangular secondary battery according to the present invention, and FIG. 2 illustrates an internal configuration of the present invention.

도면에서와 같이 본 발명의 각형 이차전지는 정극과 부극 및 세퍼레이터가 함께 권취 형성된 전극군(2)을 압착하여 캔(4)의 내부에 수납하고, 그 캔(4)의 상측 개구에 캡 어셈블리(60)를 결합하는 것이며, 그 캡 어셈블리(60)에 형성된 주입구(8)를 통해 액체 전해질을 주입한 다음 밀봉하는 구성으로 이루어진다. 전극군(2)의 하부에는 캔(4)과의 절연을 위해 절연판(10b)이 갖추어져 있다.As shown in the drawing, in the rectangular secondary battery of the present invention, the electrode group 2 formed by winding the positive electrode, the negative electrode, and the separator together is compressed and stored in the can 4, and the cap assembly ( 60), the liquid electrolyte is injected through the injection hole 8 formed in the cap assembly 60, and then it is configured to seal. The insulating plate 10b is provided in the lower part of the electrode group 2 to insulate from the can 4.

여기서 본 발명은 종래 기술의 문제점을 해결하기 위한 특징적인 구성으로 캡 어셈블리(60)와 전극군(2)의 사이에 개재되었던 상부 절연판 구조를 제거하고 있다.The present invention removes the upper insulating plate structure interposed between the cap assembly 60 and the electrode group 2 as a characteristic configuration for solving the problems of the prior art.

이를 위하여 본 발명에서는 캡 어셈블리(60)를 구성하는 것으로 부극 플레이 트(12)의 중앙 부위에 절연체(16) 및 가스켓(220)을 개재하여 정극 플레이트(14)를 적층하고, 이들을 리벳(18)으로 어셈블리함에 있어서, 상기 가스켓(220)을 전극군(2)의 상부 횡단면과 같은 크기로 형성하여, 종래의 상부 절연판의 기능을 갖도록 한다.To this end, in the present invention, the cap assembly 60 is constituted by stacking the positive electrode plates 14 through the insulator 16 and the gasket 220 in the central portion of the negative electrode plate 12, and rivets 18 of these. In the assembly, the gasket 220 is formed in the same size as the upper cross section of the electrode group 2, so as to have the function of the conventional upper insulating plate.

따라서 본 발명의 각형 이차전지는 종래 상부 절연판이 차지하였던 공간만큼 전극군(2)을 더 형성하게 되는 것이며, 이것은 전지의 용량을 향상시키도록 작용한다. 보다 구체적으로 종래 상부 절연판이 차지하였던 공간의 높이는 2㎜ 정도이다. 이 경우 본 발명의 전극군(2)을 더 확대하게 되면 대략 100mAh의 용량을 증대할 수 있다.Therefore, in the rectangular secondary battery of the present invention, the electrode group 2 is further formed as much as the space occupied by the upper insulating plate of the prior art, which serves to improve the capacity of the battery. More specifically, the height of the space occupied by the upper insulating plate is about 2 mm. In this case, if the electrode group 2 of the present invention is further enlarged, the capacity of approximately 100 mAh can be increased.

또한 본 발명에서는 캡 어셈블리(60) 밀봉 후 전해액을 주입함에 있어, 그 작업 공정을 용이하게 실현하기 위해 상기 가스켓(220)에 전해액 주입 통로(222)를 형성하고 있으며, 더불어 전지 내부 압력에 의해 작동하는 파단부(24)의 동작을 원활하게 하기 위해 파단부 통로(224)를 갖추고 있다.In addition, in the present invention, when the electrolyte is injected after sealing the cap assembly 60, the electrolyte injection passage 222 is formed in the gasket 220 to facilitate the work process, and is operated by the pressure inside the battery. The breaker passage 224 is provided to smoothly operate the breaker 24.

이렇게 형성된 캡 어셈블리(60)는 캔(4) 상부에 결합되기 전에, 먼저 정극 단자인 탭(200)과 리벳(18)을 용접하므로 전극군(2)의 정극과 전기적으로 연결되어진다. 이때 본 발명에서는 상부 절연판을 제거한 관계로 그 탭(200)과 전극군(2)의 쇼트가 발생할 수 있음을 고려하여, 상기 탭(200)을 적어도 한번 트위스트하여 탭의 상부가 아래쪽으로 처지는 것을 방지한다.The cap assembly 60 thus formed is first electrically connected to the positive electrode of the electrode group 2 by welding the tab 200 and the rivet 18, which are positive electrode terminals, before being coupled to the upper portion of the can 4. At this time, in the present invention, the tab 200 and the electrode group 2 may be shorted due to the removal of the upper insulating plate, and the tab 200 may be twisted at least once to prevent the upper part of the tab from sagging downward. do.

이상에서 설명한 구성 및 작용을 통하여 알 수 있듯이, 본 발명의 각형 이차전지는 전지를 밀폐하는 가스켓을 변경하는 방안으로 종래 기술의 문제점을 실질적으로 해소하고 있다. As can be seen through the configuration and operation described above, the rectangular secondary battery of the present invention substantially solves the problems of the prior art by changing the gasket for sealing the battery.

즉 본 발명은 상부 절연판을 제거하고 그 기능을 가스켓에 부가하므로, 실제 충·방전 반응에 기여하는 전극군의 용량을 증대할 수 있는 것이며, 그 결과로 전지의 용량을 향상시키는 효과를 얻을 수 있다.In other words, since the present invention removes the upper insulating plate and adds its function to the gasket, the capacity of the electrode group contributing to the actual charge / discharge reaction can be increased, and as a result, the effect of improving the capacity of the battery can be obtained. .

또 본 발명에 의하면 부품 수가 감소하고 전해액 주입 공정이 용이하게 실현되므로, 빠른 제조 공정과 재료비용의 절감 효과를 얻을 수 있다.In addition, according to the present invention, since the number of parts is reduced and the electrolyte injection process is easily realized, a fast manufacturing process and a material cost reduction effect can be obtained.
