본 발명은 알루미늄 및 알루미늄합금 케이스의 밀봉을 용이하게 실현하고, 아울러 그 품질을 향상시킬 수 있도록 하는데 적합한 밀폐전지 및 그 제조방법에 관한 것이다.The present invention relates to a sealed battery and a method for manufacturing the same, which are suitable for easily realizing the sealing of aluminum and aluminum alloy cases and at the same time improving the quality thereof.
밀폐전지는 외관상 원통형과 각형으로 구분되며, 양극 및 음극 물질에 따라 니켈-수소(Ni-MH) 전지, 리튬(Li) 전지, 리튬이온(Li-ion) 전지 등으로 구분된다.Sealed batteries are classified into cylindrical and rectangular in appearance, and are classified into nickel-hydrogen (Ni-MH) batteries, lithium (Li) batteries, and lithium-ion (Li-ion) batteries according to positive and negative electrode materials.
도 3은 각형 전지의 일반적인 구조를 보여주고 있다.3 shows a general structure of a square battery.
각형 밀폐전지는 외관상 캔(2)과 그 캔(2)의 상측 개구에 용접 결합되는 캡 플레이트(4)로 구성된 각형 케이스로 구성되며, 그 내부에 정극, 부극, 그리고 정극과 부극을 절연하는 세퍼레이터를 함께 권취하고 압착한 전극군(6)과 전해액을 포함하는 발전 요소를 수납하여 이루어진다. 여기서 각형 케이스는 경량화를 위해 통상 알루미늄 및 알루미늄합금으로 제조되고 있다.The rectangular sealed battery is composed of a rectangular case consisting of a can 2 and a cap plate 4 welded to an upper opening of the can 2 in appearance, and a separator for insulating a positive electrode, a negative electrode, and a positive electrode and a negative electrode therein. It is made by accommodating the power generation element including the electrode group 6 and the electrolyte solution wound together and compressed. Here, the rectangular case is usually made of aluminum and an aluminum alloy to reduce the weight.
캡 플레이트(4)에는 내부 전극군(6) 중에서 한 전극을 외부로 연결하기 위한 것으로 대략 중심을 관통하는 인출 단자(8)가 설치되는바, 그 인출 단자(8)는 전극군(6) 중에서 한 전극과 탭(18)을 통하여 연결되고, 캡 플레이트(4)와의 절연을 위해 절연판(10) 및 가스켓(12)을 개재하며 또한 접속성을 위해 단자 플레이트(14)를 개재하여 물리적으로 체결되므로 캡 어셈블리(16)를 구성한다. 한편 상기 전극군(6) 중에서 다른 전극은 캔(2)과의 직접 접촉 혹은 탭을 이용하여 전기적으로 연결되어진다.The cap plate 4 is provided with a lead terminal 8 for connecting one electrode from the internal electrode group 6 to the outside, and the lead terminal 8 passes through the center thereof. It is connected via one electrode and the tab 18, and is physically fastened through the insulating plate 10 and the gasket 12 for insulation from the cap plate 4 and through the terminal plate 14 for connectivity. Configure the cap assembly 16. On the other hand, the other electrode of the electrode group 6 is electrically connected by using direct contact with the can 2 or a tap.
이와 같은 구성을 갖는 각형 밀폐전지는 캔(2) 내부에 전극군(6)을 수납하고 그 개구에 캡 플레이트(4)를 용접한 후, 조립 공정의 마지막 단계로서 상기 캡 플레이트(4)의 한쪽에 형성된 전해액 주입구(4a)를 통해 전해액을 주입하고, 볼 혹은 핀과 같은 플러그를 이용하여 상기 주입구(4a)를 막은 후 용접하여 밀봉하고 있다.In the rectangular sealed battery having such a configuration, after storing the electrode group 6 in the can 2 and welding the cap plate 4 to the opening, one of the cap plates 4 is used as a final step of the assembling process. The electrolyte is injected through the electrolyte injection hole 4a formed in the plug, and the injection hole 4a is blocked using a plug such as a ball or a pin, and then welded and sealed.
그러나 종래 기술에 의하면 전해액 주입구(4a)와 플러그를 용접함에 따라 제조 공정이 많고 복잡하며, 용접시의 불량 발생에 의해 밀봉 품질이 나빠지는 문제점이 있다. 예를 들어 일반적으로 행해지는 저항 용접시에는 용접봉에 비해 플러그의 저항이 그렇게 크지 않기 때문에 상기 용접봉에 플러그가 달라붙어 용접 불량을 초래한다. 또 레이저 용접에 의하면 정밀 작업이 요구되고 제조 비용이 상승하는 문제점이 있다.However, according to the prior art, the welding process of the electrolyte injection port 4a and the plug are many and complicated, and there is a problem in that the sealing quality is deteriorated due to a defect in welding. For example, in the case of resistance welding, which is generally performed, the resistance of the plug is not so large as that of the electrode, so that the plug sticks to the electrode, resulting in a poor welding. In addition, the laser welding requires a precise work and there is a problem that the manufacturing cost increases.

Suggest.
또 본 발명에서는 상기 밀폐전지를 실현하기 위하여, 각형 캔의 내부에 전극군을 설치하고 상기 각형 캔의 상측 개구에 전해액 주입구가 형성된 캡 플레이트를 용접하여 알루미늄 및 알루미늄합금 케이스를 조립하는 단계와, 상기 전해액 주입구를 통해 전해액을 주입하는 단계와, 상기 주입구의 입구에 상기 케이스 보다 강도가 약한 알루미늄으로 된 정형 혹은 비정형의 플러그 재료를 배치하고 압입봉을 이용하여 강제 압입하여 밀봉하는 단계로 이루어지는 밀폐전지의 제조방법을 제안한다. In addition, in the present invention, in order to realize the sealed battery, the electrode group is installed in the inside of the rectangular can and the aluminum plate is assembled by welding a cap plate having an electrolyte injection hole formed in an upper opening of the rectangular can; Injecting an electrolyte through an electrolyte injection hole, and placing a fixed or amorphous plug material made of aluminum having a lower strength than the case at the inlet of the injection hole, and forcibly pressing and sealing the same by using a push rod.

It is made by accommodating a power generating element including an electrode group 6 and an electrolytic solution, wound together with a separator to insulate the electrode.
상기 전극군(6) 중에서 정극 및 부극은 금속 기재에 활물질을 도포 형성하여 이루어지는 바, 특히 본 발명에서는 그 일 예로서 리튬이온의 이동에 의해 충·방전이 이루어지는 리튬(이온) 전지에 대하여 설명하고 있다. 따라서 정극은 활물질로 리튬-천이금속산화물을 사용하고, 부극은 활물질로 탄소 및 탄소복합체를 사용하여 이루어진다.In the electrode group 6, the positive electrode and the negative electrode are formed by coating and forming an active material on a metal substrate. Particularly, in the present invention, a lithium (ion) battery in which charging and discharging is performed by moving lithium ions will be described. have. Therefore, the positive electrode uses lithium-transition metal oxide as the active material, and the negative electrode uses carbon and carbon composite material as the active material.
이와 같은 구성을 갖는 본 발명의 각형 밀폐전지는 각형 캔(2)의 내부에 전극군(6)을 수납하고 그 상측 개구에 캡 플레이트(4)를 용접하며, 제조 공정의 마지막 단계로 전해액 주입구(4a)를 통해 전해액을 주입한 후, 별도의 플러그(20)를 이용하여 상기 주입구를 막음에 의해 밀봉되어진다.In the rectangular sealed battery of the present invention having the configuration as described above, the electrode group 6 is housed inside the rectangular can 2, and the cap plate 4 is welded to the upper opening thereof. After injecting the electrolyte through 4a), it is sealed by blocking the injection hole using a separate plug 20.
전해액 주입구를 밀봉함에 있어, 본 발명에서는 종래와 달리 용접에 의하지 않고 소프트한 재질의 알루미늄 재료를 이용하여 용이하고 양호한 품질을 갖도록 전해액 주입구(4a)를 밀봉하고자 한다.In sealing the electrolyte inlet, the present invention intends to seal the electrolyte inlet 4a so as to have easy and good quality by using a soft aluminum material, unlike conventional welding.
이를 위하여 본 발명에서는 플러그 재료로 캡 플레이트(4) 보다 강도가 약한 순수 알루미늄(10계열 알루미늄)을 사용한다. 이때 각형 캔(2)과 캡 플레이트(4)의 재질은 제품의 경량화를 위해 알루미늄합금 예를 들어, Mn+Al(30계열 알루미늄) 혹은 Mg+Al(40계열 알루미늄)을 사용한다. 또한 상기 캡 플레이트(4)는 플러그 재료와 마찬가지로 순수 알루미늄(10계열 알루미늄)을 사용할 수도 있다.To this end, the present invention uses pure aluminum (10 series aluminum) having a lower strength than the cap plate 4 as the plug material. At this time, the material of the square can 2 and the cap plate 4 uses an aluminum alloy, for example, Mn + Al (30 series aluminum) or Mg + Al (40 series aluminum) to reduce the weight of the product. In addition, the cap plate 4 may use pure aluminum (10 series aluminum) similarly to the plug material.
이와 같은 재료에 의거하여, 본 발명의 각형 밀폐전지는 도 2에 도시한 바와 같이 캡 플레이트(4)의 전해액 주입구(4a)에 순수 알루미늄으로 된 정형 혹은 비정형의 플러그 재료(22)를 배치하고, 압입봉(24)을 이용하여 적어도 5kgf의 압력으로 강제 압입하므로 케이스의 밀봉을 실현한다.Based on such a material, in the rectangular sealed battery of the present invention, as shown in FIG. 2, a fixed or amorphous plug material 22 made of pure aluminum is disposed in the electrolyte injection hole 4a of the cap plate 4, By press-fitting the pressure at least 5 kgf using the press-fit rod 24, the case is sealed.
이때 정형 혹은 비정형의 플러그 재료(22)는 최소한 전해액 주입구(4a)의 내경 보다 큰 것이어야 하며, 압입시의 압력에 의해 캡 플레이트(4)와 강하게 물리적으로 결합되므로 전지 내부의 규정 압력에서 충분히 견딜 수 있게 된다.In this case, the at least one shaped or atypical plug material 22 should be at least larger than the inner diameter of the electrolyte inlet 4a, and is sufficiently physically coupled to the cap plate 4 by the pressure at the time of press-fitting, so that it can withstand the specified pressure inside the battery.
