Korean Patent Application Nos. 10-2018-0065250 and 2018.10.30.

본 발명은 이차전지 내부 발생 가스 실시간 분석용 챔버 및 시스템에 관한 것으로, 더욱 상세하게는 이차전지에 직접적으로 열을 가하면서 온도를 조절할 수 있는 이차전지 내부 발생 가스 실시간 분석용 챔버 및 시스템에 관한 것이다.The present invention relates to a chamber and a system for real-time analysis of a gas generated inside a secondary battery, and more particularly, to a chamber and a system for real-time analysis of a gas generated inside a secondary battery capable of controlling temperature while directly applying heat to a secondary battery. .
일반적으로, 이차전지는 화학에너지를 전기에너지로 변환하는 방전과 역방향인 충전과정을 통하여 반복 사용이 가능한 전지이며, 제품군에 따른 적용 용이성이 높고, 높은 에너지 밀도 등의 전기적 특성을 가지는 이차전지는 휴대용 기기뿐만 아니라 전기적 구동원에 의하여 구동하는 전기차량(EV, Electric Vehicle) 또는 하이브리드 차량(HV, Hybrid Vehicle) 등에 보편적으로 응용되고 있다.In general, the secondary battery is a battery that can be repeatedly used through a reverse charging and discharging process that converts chemical energy into electrical energy, and is easy to apply according to a product family, and a secondary battery having electrical characteristics such as high energy density is portable. In addition to devices, they are commonly applied to electric vehicles (EVs) or hybrid vehicles (HVs), which are driven by electric driving sources.
이러한 이차전지 내에서 발생하는 가스를 포집하여 분석함에 있어서 이차전지의 작동시에 다양한 가스가 발생하며, 이러한 이차전지 발생가스의 조성 및 함량에 대한 정보는 전지소재의 개발, 전지제조공정 최적화, 전지 불량원인의 파악 등에 있어 유용하게 이용된다. In collecting and analyzing the gas generated in the secondary battery, various gases are generated during operation of the secondary battery, and information on the composition and content of the secondary battery generated gas may be developed in battery material development, battery manufacturing process optimization, and battery. It is useful for identifying the cause of defect.
한편, 종래의 이차전지 내부 발생 가스를 분석하기 위한 챔버에서는, 전지에 온도 차이에 따른 가스 발생 분석을 진행하기 위해서는 챔버 전체를 내부에 포함시킬 수 있는 오븐(oven)과 같은 외부 가열 장치를 사용하여 이러한 오븐으로 챔버에 열을 가하여 챔버의 온도를 상승시켜서 챔버 내 전지의 온도를 상승시킨다. 이러한 종래의 챔버에서는, 전지의 고온 특성에 대한 연구를 진행하는데 있어서 전지 내 발생 가스를 분석하기에는 전지에 직접적인 온도를 가할 수 없다는 한계가 있다. 직접적으로 전지에 열을 가하지 않기 때문에 원하는 정확한 온도를 전지에 인가시킬 수 없다는 단점이 있다. 또한, 챔버 재질의 비열 특성으로 인하여 온도 상승을 위한 오랜 시간이 요구된다.On the other hand, in the conventional chamber for analyzing the gas generated inside the secondary battery, in order to proceed with the gas generation analysis according to the temperature difference in the battery using an external heating device such as an oven (oven) that can include the entire chamber inside The oven heats the chamber to raise the temperature of the chamber, thereby raising the temperature of the battery in the chamber. In such a conventional chamber, there is a limitation in that a direct temperature cannot be applied to the cell in order to analyze gas generated in the cell in the study of the high temperature characteristic of the cell.

In addition, such a chamber 100 may also be capable of being separated into the chamber body 101 and the chamber cover 102 as shown in FIG. In other words, the chamber body 101 may be provided, for example, in a rectangular parallelepiped shape in which the front part is opened, and the chamber cover 102 may be provided to shield the opening of the chamber body 101.

More specifically, the chamber body 101 has a double structure, that is, the secondary battery 20 may be mounted therein and surrounds the first housing 100a and the first housing 100a in which the front part is opened, but the front part is similarly opened. It may be composed of a second housing (100b), the chamber cover 102 also has a double structure like the chamber body 101, of the chamber cover covering the first housing (100a) of the chamber body 101 The second housing 100b of the chamber cover covering the first housing 100a and the second housing 100b of the chamber body 101 may be configured.
챔버 본체(101) 및 챔버 커버(102)는 고정핀, 나사, 볼트, 등의 고정 수단으로 단단히 결합될 수 있다. 챔버 본체(101) 및 챔버 커버(102) 사이의 접촉면에는 챔버 본체(101) 및 챔버 커버(102)의 결합시 밀폐를 위한 O-ring 등과 같은 밀폐 부재를 더 포함할 수 있다.The chamber body 101 and the chamber cover 102 may be tightly coupled with fixing means such as fixing pins, screws, bolts, and the like. Chamber Body 101 and Chamber Cover 102 The contact surface therebetween may further include a sealing member such as an O-ring for sealing when the chamber body 101 and the chamber cover 102 are coupled.
챔버(100)에는 펌프 모듈(210)이 연결될 수 있는 주입구(110)와 분석 모듈(220)이 연결될 수 있는 방출구(120)가 구비되어 있다. The chamber 100 is provided with an inlet 110 through which the pump module 210 can be connected and an outlet 120 through which the analysis module 220 can be connected.
도 1을 참조하면, 펌프 모듈(210)은 챔버(100)에 구비된 주입구(110)를 통하여 비활성 가스 등으로 이루어지는 유도 매체를 챔버(100) 내부로 유입시킨다. 펌프 모듈(210)은 MFC(Mass flow meter) 등의 가스 매체를 이동 시키는 장치를 포함한다. 펌프 모듈(210)과 주입구(110)는 가스 이동 흐름이 생성될 수 있도록 유도관으로 연결되어 있다. 비활성 가스 등으로 이루어지는 유도 매체는 헬륨, 질소, 아르곤 등과 같은 비활성 가스로 구성하는 것이 바람직하지만, 유도 매체를 구성하는 가스 성분은 검출하고자 하는 이차전지 발생 가스의 성분 및 이차전지 발생 가스의 분석의 목적에 따라 적절하게 선택될 수도 있음은 물론이다.Referring to FIG. 1, the pump module 210 introduces an induction medium made of inert gas into the chamber 100 through an injection hole 110 provided in the chamber 100. The pump module 210 includes a device for moving a gas medium such as a mass flow meter (MFC). The pump module 210 and the inlet 110 are connected to the induction pipe so that the gas flow flow can be generated. The induction medium made of an inert gas or the like is preferably composed of an inert gas such as helium, nitrogen, argon, etc., but the gas component constituting the induction medium may be a component of a secondary battery generating gas and a secondary battery generating gas to be detected Of course, it may be appropriately selected depending on.
펌프 모듈(210)에서 유량을 조절하여 챔버(100)의 내부 공간으로 유도 매체를 강하게 유입시킬 수 있고, 챔버(100)에 유입된 유도 매체는 챔버(100)의 주입구(110)와 방출구(120) 사이의 기압차이로 인하여 방출구(120)를 통하여 챔버(100)를 빠져나가게 된다. 이러한 유도 매체의 이송 흐름에 의하여, 이차전지(20)에서 발생되는 내부 가스가 유도 매체와 함께 방출구(120)를 통하여 분석 모듈(220)로 이송된다.By controlling the flow rate in the pump module 210 to strongly introduce the induction medium into the interior space of the chamber 100, the induction medium introduced into the chamber 100 is the inlet 110 and the outlet of the chamber 100 ( Due to the pressure difference between the 120 is to exit the chamber 100 through the discharge port (120). By the transfer flow of the induction medium, the internal gas generated in the secondary battery 20 is transferred to the analysis module 220 through the discharge port 120 together with the induction medium.

본 발명에 따르면, 가열 부재(140)는 제 2 하우징(100b)의 내부(즉, 제 2 하우징(100b)으로 둘러싸인 공간이 아닌, 제 2 하우징(100b) 자체)에 삽입될 수 있는 것으로 구현된다. 보다 구체적으로, 가열 부재(140)는 제 2 하우징(100b)의 적어도 일면의 내부에 삽입될 수 있다. 가열 부재(140)는 도 4b 에서도 도시된 바와 같이, 제 1 하우징(100a)으로 둘러싸여 형성되는 내부 공간으로 노출되지 않아, 이차전지(20)와 직접적으로 접촉되지는 않는다. According to the present invention, the heating member 140 is implemented as being able to be inserted into the interior of the second housing 100b (that is, not the space surrounded by the second housing 100b, but the second housing 100b itself). . More specifically, the heating member 140 may be inserted into at least one surface of the second housing 100b. As shown in FIG. 4B, the heating member 140 is not exposed to an inner space formed by being surrounded by the first housing 100a, so that the heating member 140 does not directly contact the secondary battery 20.
한편, 종래에는 상술한 바와 같이 챔버의 외부에 챔버 온도를 높이기 위한 오븐을 구비하여 외부에 마련된 오븐으로부터 챔버에 열을 가하기 때문에 이차전지의 온도를 높이는 데에 상당한 시간이 소요될 뿐만 아니라 이차전지를 원하는 온도로 정확하게 가열하는 데에 어려움이 있었다.Meanwhile, in the related art, since the oven is provided outside the chamber to increase the chamber temperature, heat is applied to the chamber from an oven provided outside, and thus, a considerable time is required to increase the temperature of the secondary battery, and a secondary battery is desired. There was a difficulty in heating accurately to temperature.
본 발명에 따른 가열 부재(140)는 예시적으로 도 1 및 2에 도시된 바와 같이, 바(bar, 막대기) 형상으로 구현될 수 있다. 부연하면, 가열 부재(140)를 출력이 높은 바(bar) 형상으로 본 발명을 구현할 수 있다. 도 1 및 2에서는, 예시적으로, 파우치 형의 이자전지(20)를 가열하는 경우에 2 개의 가열 부재(140)들이 제 2 하우징(100b)의 일면의 내부 중 상부와 하부에 각각 삽입되는 경우를 도시하고 있다. 그러나, 본 발명은 상술한 것에 한정되지 않고, 가열 부재(140)가 제 2 하우징(100b) 내부에 삽입되어 이차전지(20)를 가열할 수 있는 한, 가열 부재(140)의 형상, 개수, 및 제 2 하우징(100b)에 삽입되는 위치는 변형, 변경이 가능하다. 또한, 가열 부재(140)는 열전도성의 물질로서, 니켈, 크롬, 또는 알루미늄 등의 재질로 이루어 질 수 있다. As illustrated in FIGS. 1 and 2, the heating member 140 according to the present invention may be implemented in a bar shape. In other words, the present invention can be implemented in a bar shape having a high output of the heating member 140. 1 and 2, in the case of heating the pouch-type rechargeable battery 20, two heating members 140 are respectively inserted into upper and lower portions of the inside of one surface of the second housing 100b. Is shown. However, the present invention is not limited to the above description, and as long as the heating member 140 can be inserted into the second housing 100b to heat the secondary battery 20, the shape, number, And a position inserted into the second housing 100b may be modified or changed. In addition, the heating member 140 may be made of a material such as nickel, chromium, or aluminum as a thermally conductive material.
또한, 상술한 바와 같이, 제 2 하우징(100b)은 열전도성의 물질로서, SUS, 금속 등의 재질로 이루어 질 수 있으므로, 제 2 하우징(100b) 자체에 삽입된 가열 부재(140)에 의하여 제 2 하우징(100b)이 가열될 수 있다. 그에 따라, 제 2 하우징(100b) 내의 제 1 하우징(100a)을 통하여 제 1 하우징(100a) 내부에 장착된 이차전지(20)가 가열될 수 있다. In addition, as described above, since the second housing 100b is a thermally conductive material and may be made of a material such as SUS or metal, the second housing 100b may be formed of the second housing 100b by the heating member 140 inserted into the second housing 100b itself. The housing 100b may be heated. Accordingly, the secondary battery 20 mounted in the first housing 100a may be heated through the first housing 100a in the second housing 100b.
한편, 가열 부재(140)에 의하여 가열된 제 2 하우징(100b)과 이차전지(20) 사이에 절연성의 제 1 하우징(100a)이 위치하고 있으므로, 가열된 제 2 하우징(100b)이나 가열 부재(140)에 이차전지(20)가 직접적으로 접촉되지는 않아, 이차전지(20)의 폭발, 발화의 위험성을 방지하였다. 만약, 제 1 하우징(100a)이 구비되지 않는다면, 이차전지(20)가 가열된 제 2 하우징(100b)이나 가열 부재(140)에 직접적으로 접촉되어, 쇼트(short)로 인한 이차전지(20)의 안전성 문제가 발생할 우려가 있다. 또한, 제 1 하우징(100a)은, 가열부재(140)가 삽입된 제 2 하우징(100b)에 의하여 가열되는 열이 이차전지(20)로 충분히 전달될 수 있도록, 가능한 한 얇게 형성되는 것이 바람직하다. Meanwhile, since the insulating first housing 100a is positioned between the second housing 100b heated by the heating member 140 and the secondary battery 20, the heated second housing 100b or the heating member 140 is located. ) Does not directly contact the secondary battery 20, thereby preventing the risk of explosion and ignition of the secondary battery 20. If the first housing 100a is not provided, the secondary battery 20 is in direct contact with the heated second housing 100b or the heating member 140, and thus the secondary battery 20 is shorted. There is a risk of safety problems. In addition, the first housing 100a is preferably formed as thin as possible so that the heat heated by the second housing 100b into which the heating member 140 is inserted can be sufficiently transferred to the secondary battery 20. .
온도 센서(150)의 일단부는 제 1 하우징(100a)으로 둘러싸인 내부 공간에 노출되고, 또한, 이차전지(20)의 외부의 온도(즉, 챔버(100) 내부의 온도)를 측정할 수 있도록 온도 센서(150)의 일단부가 이차전지(20)에 근접하게 위치하거나 이차전지(20) 자체의 온도를 측정할 수 있도록 온도 센서(150)의 일단부가 이차전지(20)에 접하도록 위치하는 것이 바람직하다.One end of the temperature sensor 150 is exposed to the internal space surrounded by the first housing 100a, and further, the temperature of the temperature sensor 150 to measure the temperature outside the secondary battery 20 (that is, the temperature inside the chamber 100). One end of the sensor 150 may be located near the secondary battery 20, or one end of the temperature sensor 150 may contact the secondary battery 20 so that the temperature of the secondary battery 20 may be measured. Do.
온도 센서(150)와 가열 부재(140)는 각각 온도 조절 모듈(240)에 연결되어 있다. 온도 조절 모듈(240)은 온도 센서(150)를 통하여 이차전지(20)의 온도 또는 챔버(100) 내부의 온도를 측정하고 가열 부재(140)를 통하여 희망하는 온도로 이차전지(20)를 가열하는 것을 제어한다. 따라서, 이차전지(20) 내부 발생 가스를 분석할 때에, 이차전지(20)에 가하는 온도를 실시간으로 조절하면서 분석을 수행할 수 있다.The temperature sensor 150 and the heating member 140 are each connected to the temperature control module 240. The temperature control module 240 measures the temperature of the secondary battery 20 or the temperature inside the chamber 100 through the temperature sensor 150 and heats the secondary battery 20 to a desired temperature through the heating member 140. To control. Therefore, when analyzing the gas generated inside the secondary battery 20, the analysis may be performed while controlling the temperature applied to the secondary battery 20 in real time.
챔버(100)는 챔버(100) 내부의 압력을 측정하는 압력게이지(미도시)를 더 포함할 수 있다.The chamber 100 may further include a pressure gauge (not shown) for measuring the pressure inside the chamber 100.
한편, 본 발명의 이차전지 내부 발생 가스 분석 시스템(10)에서는, 보다 정확한 결과값을 도출할 수 있도록 실험전 챔버(100) 내부가 진공 상태로 조성될 수 있다. 이를 위해 이차전지 내부 발생 가스 분석 시스템(10)은 챔버(100)와 연결되어 챔버(100) 내부에 진공 상태를 조성하는 진공펌프(미도시)를 더 구비할 수 있다.On the other hand, in the secondary battery internally generated gas analysis system 10 of the present invention, the inside of the chamber 100 before the experiment may be formed in a vacuum state so as to derive a more accurate result value. To this end, the secondary battery internally generated gas analysis system 10 may further include a vacuum pump (not shown) connected to the chamber 100 to form a vacuum state in the chamber 100.

According to the chamber 100 according to the present invention, while the role of the chamber for real-time gas analysis is basically performed, in addition to the temperature directly applied to the secondary battery, there is an advantage that the temperature applied to the secondary battery can be adjusted. .

또한, 가열 부재가 챔버의 제 2 하우징에 삽입됨으로써, 이차전지를 직접적으로 신속하게 가열하면서도 보다 안전하게 이차전지를 가열할 수 있는 장점이 있다. 즉, 이차전지와 직접적으로 닿는 제 1 하우징에 가열 부재가 삽입되거나 챔버의 이차전지가 장착된 내부 공간에 가열부재가 위치하는 경우에는 전지가 폭발할 우려가 있을 수 있으므로, 이러한 이차전지 가열시의 안전성 문제의 우려를 해결하면서도 신속하게 이차전지를 가열할 수 있는 장점이 있다.In addition, since the heating member is inserted into the second housing of the chamber, there is an advantage that the secondary battery can be heated more safely while directly heating the secondary battery directly and quickly.
