본 발명은 이상 전류 차단장치를 갖는 배터리에 관한 것으로, 보다 상세하게는 공정 단가를 절감할 수 있고, 전지 효율성을 향상시킬 수 있으며, 전극 탭과 PCM 탭간의 용접 불량을 방지할 수 있는 배터리에 관한 것이다.The present invention relates to a battery having an abnormal current blocking device, and more particularly, to a battery which can reduce process cost, improve battery efficiency, and prevent welding failure between an electrode tab and a PCM tab. will be.

비디오 카메라, 휴대용 전화, 휴대용 PC 등의 휴대용 무선 기기제품과 전기 자전거, 전기자동차, 전동공구 등의 경량화 및 고기능화가 진행됨에 따라, 그 구동용 전원으로서 사용되는 전지에 대해서 중요성이 증가되고 있고, 많은 연구가 이루어지고 있다.As portable wireless device products such as video cameras, portable telephones, portable PCs, and electric bicycles, electric vehicles, and electric tools have become lighter and more functional, batteries used as driving power have increased in importance. Research is being done.

특히, 충, 방전이 가능한 리튬 2차 전지는 기존의 납 축전지, 니켈-카드뮴 전지, 니켈-수소전지, 니켈-아연전지 등과 비교하여 단위 중량당 에너지 밀도가 3배 정도 높고 급속 충전이 가능하기 때문에 연구 개발이 활발하게 진행되고 있다.In particular, lithium rechargeable batteries that can be charged and discharged have three times the energy density per unit weight and can be rapidly charged compared to conventional lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, and nickel-zinc batteries. Research and development is active.

리튬 2차 전지는 전해질 종류에 따라 액체 전해질을 사용하는 리튬 금속 전지와 리튬 이온 전지와, 고분자 고체 전해질을 사용하는 리튬 이온 폴리머 전지로 구분할 수 있으며, 리튬 이온 폴리머 전지는 고분자 고체 전해질의 종류에 따라 유기 전해액이 전혀 함유되어 있지 않은 완전 고체형 리튬 이온 폴리머 전지와, 유기 전해액을 함유하고 있는 겔형 고분자 전해질을 사용하는 리튬 이온 폴리머 전지로 나눌 수 있다.Lithium secondary batteries can be classified into lithium metal batteries, lithium ion batteries using liquid electrolytes, and lithium ion polymer batteries using polymer solid electrolytes, depending on the type of electrolyte. It can be divided into a fully solid lithium ion polymer battery containing no organic electrolyte and a lithium ion polymer battery using a gel polymer electrolyte containing an organic electrolyte.

그리고, 상기 2차 전지가 사용되는 대부분의 기기에서는 PCM(Protection Circuit Module)과 같은 보호 회로가 사용된다.And, in most devices using the secondary battery, a protection circuit such as a protection circuit module (PCM) is used.

상기 보호 회로는 배터리의 충,방전시 안전 회로가 구동되도록 하여 과충전 보호, 과방전 보호, 과전류가 차단되도록 함으로써 배터리를 폭발 위험으로부터 보호하고 수명 연장과 고성능화를 유지할 수 있도록 한다.The protection circuit allows the safety circuit to be driven during charging and discharging of the battery so that overcharge protection, overdischarge protection, and overcurrent are blocked to protect the battery from the risk of explosion and to prolong life and maintain high performance.

도 1에는 종래 기술에 따른 PCM을 갖는 리튬 이온 폴리머 전지의 구조를 개략적으로 도시한 도면이 도시되어 있다.1 is a view schematically showing the structure of a lithium ion polymer battery having a PCM according to the prior art.

첨부된 도면을 참조하면, 세부적으로 상세하게는 도시되지 않았지만, 상기 리튬 이온 폴리머전지는 그리드(Grid)에 전극 활물질을 충전시킨 양극판과 음극판 및 유기 전해액이 함침되어 있는 세퍼레이터(Seperator)가 적층된 구조로 되어 있는 전지 셀(C)을 구비한다.Referring to the accompanying drawings, although not shown in detail, the lithium ion polymer battery has a structure in which a positive electrode plate, a negative electrode plate, and a separator in which an organic electrolyte is impregnated with an electrode active material filled in a grid are stacked. A battery cell C is provided.

또한 양극판과 음극판의 일측에는 각각 전극 탭(T1,T2)이 형성되고, 상기 전극 탭(T1,T2)은 일정한 간격을 두고 나란하게 배치된다.In addition, electrode tabs T1 and T2 are formed at one side of the positive electrode plate and the negative electrode plate, respectively, and the electrode tabs T1 and T2 are arranged side by side at regular intervals.

상술한 전지 셀(C) 및 전극 탭(T1,T2)은 도시하지 않은 커버가 형성된 절연성 케이스에 의해 밀봉되거나 파우치 등에 의해 밀봉된다. 상기 절연성 케이스는 통상적으로 알루미늄 박막의 상, 하면 위에 열접착성 물질이 적층된 파우치 형태 또는 케이스 형태를 가지며, 열접착성 물질이 상호 접착됨으로써 그 내부를 밀봉하고 있다.The battery cell C and the electrode tabs T1 and T2 described above are sealed by an insulating case with a cover (not shown) or sealed by a pouch or the like. The insulating case generally has a pouch form or a case form in which a heat adhesive material is laminated on upper and lower surfaces of an aluminum thin film, and the inside of the insulating case is sealed by mutual bonding of the heat adhesive materials.

그리고, 상기 전극 탭(T1,T2)에는 PCM(100)의 탭(T3,T4)이 각각 부착되는데, 상기 탭(T3,T4)은 대략 "ㄴ"자 형상을 가지며, PCM(100)으로부터 전지 셀(C) 쪽으로 돌출 형성된다. 이에 따라, 전극 탭(T1.T2)과 PCM(100)의 탭(T3,T4)을 각각 용접한 후에는 제1 절곡선(BL1)에서 PCM(100)의 탭(T3,T4)을 1회 절곡하고, 이후 제2 절곡선(BL2)에서 전극 탭(T1,T2)을 1회 절곡하여 전지 셀(C)의 PCM 설치 공간(C')에 PCM(100)을 전면(F)이 노출되도록 설치하게 된다.In addition, the tabs T3 and T4 of the PCM 100 are attached to the electrode tabs T1 and T2, respectively, and the tabs T3 and T4 have a substantially “b” shape and are separated from the PCM 100. Protruding toward the cell (C). Accordingly, after welding the electrode tabs T1.T2 and the tabs T3, T4 of the PCM 100, respectively, the taps T3, T4 of the PCM 100 are once-twisted at the first bend line BL1. After bending, the electrode tabs T1 and T2 are bent once on the second bending line BL2 so that the front surface F of the PCM 100 is exposed to the PCM installation space C ′ of the battery cell C. Will be installed.

Since the PCM installation space is a separate space from the battery capacity, there is a problem in that the efficiency of the battery is deteriorated because the space for determining the battery capacity is limited with respect to the overall size of the battery.

또한, 상기 알루미늄재 전극 탭과 니켈재 PCM 탭간에 용접 불량이 발생되는 문제점이 있다.In addition, there is a problem that a welding failure occurs between the aluminum electrode tab and the nickel-based PCM tab.

이에, 본 발명은 상기 문제점을 해결하기 위한 것으로, 공정 단가를 절감할 수 있고, 전지 효율성을 향상시킬 수 있으며, 전극 탭과 PCM 탭간의 용접 불량을방지할 수 있는 배터리를 제공함을 목적으로 한다.Accordingly, an object of the present invention is to provide a battery that can reduce the process cost, improve battery efficiency, and prevent welding failure between the electrode tab and the PCM tab.
