Description
본 발명은 조립 공정을 용이하게 실현할 수 있도록 한 이차전지의 캔에 관한 것이다.The present invention relates to a can of a secondary battery in which an assembly process can be easily realized.
이차전지는 재충전이 가능하고 소형 및 대용량화가 가능한 것으로, 대표적으로는 니켈수소(Ni-MH)전지와 리튬(Li)전지 및 리튬이온(Li-ion)전지가 사용되고 있으며, 외관상으로는 원통형과 각형 전지로 구분되고 있다.Rechargeable batteries can be recharged, miniaturized and large-capacity. Representatively, nickel-hydrogen (Ni-MH) batteries, lithium (Li) batteries, and lithium-ion (Li-ion) batteries are used. It is divided into battery.
도 3은 나선형(spirally-wound) 전극부를 갖는 원통형 이차전지의 일반적은 구성을 나타내고 있다. 도면에서와 같이 원통형 이차전지는 정극과 부극의 사이에 세퍼레이터를 개재하여 함께 권취한 전극부(2)를 액체 전해질과 함께 캔(4)의 내부에 수납하고, 그 캔의 상부에 가스켓(6)을 개재하여 캡 어셈블리(8)를 설치한 구성으로 이루어진다.3 illustrates a general configuration of a cylindrical secondary battery having a spirally-wound electrode portion. As shown in the drawing, the cylindrical secondary battery accommodates the electrode portion 2 wound together with a liquid electrolyte between the positive electrode and the negative electrode in the can 4 together with the liquid electrolyte, and the gasket 6 on the top of the can. The cap assembly 8 is installed through the configuration.
캡 어셈블리(8)는 정극 단자로 사용되는 것으로 전극부(2)의 정극에서 인출된 탭(10)과 전기적으로 연결된다. 반면 캔(4)은 전극부(2)의 부극에서 인출된 탭(도시생략) 혹은 최외곽부의 부극과 직접 접촉하는 것으로 부극 단자로 사용되어진다.The cap assembly 8 is used as a positive electrode terminal and is electrically connected to the tab 10 drawn from the positive electrode of the electrode portion 2. On the other hand, the can 4 is used as a negative electrode terminal in direct contact with a tab (not shown) drawn from the negative electrode of the electrode portion 2 or the negative electrode of the outermost portion.
이와 같이 구성된 이차전지에서, 캔(4)은 상부에 비딩부(4a)를 형성하고 여기에 가스켓(6)과 캡 어셈블리(8)를 올려놓은 상태에서, 그 상측 단부를 크림핑하여 밀봉하게 된다. 이때 크림핑 공정에서는 충·방전시 전지 내부에서 발생하는 가스 압력을 고려하여 가스켓(6)을 적어도 30%까지 프레스한다.In the secondary battery configured as described above, the can 4 has a beading portion 4a formed thereon and the gasket 6 and the cap assembly 8 are placed thereon, and the upper end thereof is crimped and sealed. . At this time, in the crimping process, the gasket 6 is pressed to at least 30% in consideration of the gas pressure generated in the battery during charging and discharging.
그러나 캔(4)의 상측에 가스켓(6)과 캡 어셈블리(8)를 적층하고 30%까지 압축하여 실링하는 공정은 부품들이 많아 복잡하고 기술적으로 어렵기 때문에, 조립 및 압축성 불량이 종종 발생되고 있다. 또한 상기와 같은 이유로 전지의 조립성 및 생산성이 저하되는 문제점이 있다.However, the process of laminating the gasket 6 and the cap assembly 8 on the top of the can 4 and compressing and sealing up to 30% is often complicated and technically difficult due to the large number of parts. . In addition, there is a problem that the assembly and productivity of the battery is lowered for the same reason.
앞서 설명한 종래 기술의 문제점을 해소하기 위한 것으로서, 본 발명은 전지의 밀폐성을 향상시키면서도 용이한 조립을 실현할 수 있도록 한 이차전지의 캔을 제공함에 그 목적을 두고 있다.SUMMARY OF THE INVENTION In order to solve the problems of the prior art described above, the present invention aims to provide a can of a secondary battery that enables easy assembly while improving the sealing property of the battery.

이하, 본 발명의 바람직한 실시예를 첨부 도면에 의거하여 보다 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described in detail based on an accompanying drawing.
도 1은 본 발명에 의한 이차전지의 전체 구조를 보여주고 있다.Figure 1 shows the overall structure of a secondary battery according to the present invention.
본 발명에서는 원통형 구조를 갖는 이차전지의 하나로 리튬이온전지를 일 예로 설명하기로 한다. 리튬이온전지는 정극 활물질로 LiCoO_2, LiNiO_2 및중에서 적어도 1종이 함유된 리튬-천이금속산화물을 사용하고, 부극 활물질로 탄소 및 탄소복합체를 사용한다.In the present invention, one of the secondary batteries having a cylindrical structure will be described as a lithium ion battery as an example. Lithium ion battery is a positive electrode active material LiCoO_2, LiNiO_2 and Lithium-transition metal oxide containing at least one of them is used, and carbon and a carbon composite material are used as the negative electrode active material.
전극 기재에 활물질을 도포 및 충전하여 형성된 정극 및 부극은 사이에 세퍼레이터를 개재하여 절연된 상태에서 맨드렐을 이용하여 권취되므로 롤 상의 전극부(12)를 형성하게 된다.Since the positive electrode and the negative electrode formed by applying and filling the active material on the electrode base material are wound using a mandrel in an insulated state through a separator therebetween, the electrode portion 12 on the roll is formed.
이렇게 형성된 전극부(12)는 전해액과 함께 케이스의 내부로 수납되어지는 바, 본 발명에서는 상기 케이스를 형성함에 있어 상부 캔(14a)과 하부 캔(14b)으로 분리 형성하고, 양 캔(14a)(14b)의 단부에 수나사(16a)와 암나사(16b)를 형성하여서 나사 결합방식에 의해 용이하게 조립할 수 있도록 한다.The electrode part 12 formed as described above is accommodated inside the case together with the electrolyte. In the present invention, the electrode part 12 is separated into an upper can 14a and a lower can 14b in forming the case, and both cans 14a are formed. The male screw 16a and the female screw 16b are formed at the ends of the 14b so that they can be easily assembled by the screwing method.
또 상부 캔(14a)의 수나사(16a) 외주에 밀폐성을 향상시키기 위한 0-링(18)을 설치할 수 있다.Moreover, the 0-ring 18 for improving the sealing property can be provided in the outer periphery of the male screw 16a of the upper can 14a.
이와 같이 구성된 본 발명의 캔(14a)(14b) 내부에 전극부(12)를 삽입하기 위하여, 먼저 상부 캔(14a)에 2개의 구멍(140)을 형성하고, 전극부(12)에서 인출된 정극 탭(12a) 및 부극 탭(12b)을 관통하여 외부로 인출되게 한다.In order to insert the electrode portion 12 into the cans 14a and 14b of the present invention configured as described above, first, two holes 140 are formed in the upper can 14a and drawn out from the electrode portion 12. It penetrates through the positive electrode tab 12a and the negative electrode tab 12b to the outside.
정극 탭(12a)과 부극 탭(12b)은 캔(14a)과 절연되어야 하므로 상기 구멍(140)에 절연 실링제(20)를 채워 넣고 실링한다. 이때 상기 구멍(140)에는 사전에 절연링을 삽입할 수도 있다.Since the positive electrode tab 12a and the negative electrode tab 12b are to be insulated from the can 14a, an insulating sealing agent 20 is filled in the hole 140 and sealed. In this case, an insulating ring may be inserted into the hole 140 in advance.
전극부(12)는 상·하부에 각각 절연판(22)을 삽입하여 캔(14a)(14b)과 절연된다. 전극부(12)가 삽입된 상부 캔(14a)을 고정하고, 하부 캔(14b)의 암나사(16b)를 상부 캔(14a)의 수나사(16a)에 맞추어 체결함으로써 본 발명의 이차전지를 용이하게 조립할 수 있다.The electrode portion 12 is insulated from the cans 14a and 14b by inserting the insulating plate 22 into the upper and lower portions, respectively. The secondary battery of the present invention can be easily fixed by fixing the upper can 14a in which the electrode part 12 is inserted and fastening the female screw 16b of the lower can 14b to the male screw 16a of the upper can 14a. Can be assembled.
이렇게 조립된 이차전지의 상부 캔(14a) 혹은 하부 캔(14b)에는 전해액 주입구(142)를 형성하고, 전해액 주입 후 플러그를 이용하여 밀봉할 수 있다.An electrolyte injection hole 142 may be formed in the upper can 14a or the lower can 14b of the assembled secondary battery, and may be sealed by using a plug after the electrolyte is injected.
한편 도 2는 본 발명의 다른 예를 보여주고 있다.2 shows another example of the present invention.
여기서 본 발명은 일반적인 원통형 이차전지의 구조를 그대로 채용하고 있으며, 다만 케이스를 상부 캔(24a)과 하부 캔(24b)으로 분리하여 나사 결합방식에 의해 용이하게 조립할 수 있도록 하고 있다.Herein, the present invention employs a structure of a general cylindrical secondary battery as it is, but separates the case into an upper can 24a and a lower can 24b so that it can be easily assembled by a screw coupling method.
상부 캔(24a)에는 가스켓(26)을 개재하여 캡 어셈블리(28)가 설치되며, 캡 어셈블리(28)는 안전변을 갖춘 플레이트(30)와 캡 커버(32)의 순서로 적층되고, 안전변을 갖춘 플레이트(30) 하부에 절연체(34)를 개재하여 전류차단기(36)를 용접한 구성으로 이루어진다. 전류차단기(36)는 탭(38)을 이용하여 전극부(12)의 정극과 연결된다.The cap assembly 28 is installed in the upper can 24a via the gasket 26, and the cap assembly 28 is stacked in the order of the plate 30 having the safety valve and the cap cover 32. The current circuit breaker 36 is welded through the insulator 34 under the plate 30. The current breaker 36 is connected to the positive electrode of the electrode part 12 using the tab 38.
또 본 발명의 상부 캔(24a) 혹은 하부 캔(24b)은 전극부(12)의 부극에서 인출된 탭(도시생략) 혹은 최외곽부의 부극과 직접 접촉하는 방식으로 부극 단자로 사용되어진다.In addition, the upper can 24a or the lower can 24b of the present invention is used as a negative electrode terminal in a manner of directly contacting a tab (not shown) drawn from the negative electrode of the electrode portion 12 or the negative electrode of the outermost part.
이상에서 설명한 구성 및 작용을 통하여 알 수 있듯이, 본 발명의 이차전지의 캔은 나사 결합방식을 이용하여 조립함으로써 종래 기술의 문제점을 실질적으로 해소하고 있다.As can be seen through the configuration and operation described above, the can of the secondary battery of the present invention is substantially solved the problems of the prior art by assembling using a screw coupling method.
즉 본 발명에 의하면 가스켓이나 복잡한 크림핑 공정을 제거함으로써, 조립 공정을 용이하게 실현할 수 있으며, 그 결과 생산성이 향상되는 효과를 얻을 수 있다.That is, according to the present invention, the assembly process can be easily realized by removing the gasket and the complicated crimping process, and as a result, the productivity can be improved.
또 본 발명에 의하면 상부 캔과 하부 캔을 나사 결합방식으로 체결하므로,밀폐성을 향상시키고 내부 가스와 전해액의 누수를 효과적으로 방지할 수 있다.In addition, according to the present invention, since the upper can and the lower can are fastened by screwing, the sealing property can be improved and the leakage of the internal gas and the electrolyte can be effectively prevented.
아울러 본 발명에 의하면 부품의 수가 줄어 제품의 구조가 단순화 및 경량화되는 효과를 얻을 수 있고, 제품의 제조비용이 절감되는 효과를 얻을 수 있다.In addition, according to the present invention, the number of parts can be reduced, so that the structure of the product can be simplified and lighter, and the manufacturing cost of the product can be reduced.
