결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀{Laminate type battery cell improved assembly and cooling structure}Laminate type battery cell improved assembly and cooling structure

본 발명은 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀에 관한 것으로, 더욱 상세하게는 다수의 배터리 셀을 균일하게 냉각할 수 있도록 냉각 구조가 개선된 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀에 관한 것이다.The present invention relates to a laminated battery cell having an improved coupling and cooling structure, and more particularly, to a laminated battery cell having an improved coupling and cooling structure for cooling a plurality of battery cells uniformly. It is about.

일반적으로 라미네이트형(laminate type, 박판형) 배터리 셀은 배터리 셀의 외장이 라미네이트 부재로 되어 있어 배터리 셀의 외주부가 얇은 막을 이루는 형상이기 때문에 정확한 위치 결정이나 안정적인 고정이 어려웠다.In general, a laminate type (thin plate) battery cell is a laminate member because the exterior of the battery cell is a laminate member, so it is difficult to accurately position or secure the battery cell.

첨부된 도 1은 종래의 라미네이트형 배터리 셀의 고정 구조를 도시한 사시도이고, 도 2는 도 1에 따른 라미네이트형 배터리 셀의 냉각 구조를 도시한 사시도이다.1 is a perspective view showing a fixing structure of a conventional laminated battery cell, Figure 2 is a perspective view showing a cooling structure of the laminated battery cell according to FIG.

도 1에 도시된 바와 같이, 종래에는 사각 프레임(10)에 복수의 배터리 셀(20)을 병렬로 배치한 후 다시 여러 개의 사각 프레임(10)을 적층하는 구조이며, 이렇게 적층된 사각 프레임(10)은 도 2에 도시된 바와 같이, 케이스(32)에 삽입되어 냉기유입덕트(34) 및 냉기배출덕트(36)와 연결되었다.As illustrated in FIG. 1, in the related art, a plurality of battery cells 20 are arranged in parallel in a square frame 10, and a plurality of square frames 10 are stacked again, and the stacked square frames 10 are stacked. As shown in FIG. 2, the case 32 is inserted into the case 32 and connected to the cold air inlet duct 34 and the cold air discharge duct 36.

냉각장치(30)에는 배기 팬(38)이 설치되어 냉기유입덕트(34)를 통해 냉각풍이 유입되도록 하고, 유입된 냉각풍은 프레임(10)에 형성된 냉기유입구(12)로 공급되어 배터리 셀(20)들을 냉각한 후 냉기배출구(14)로 배출된다. 배출된 공기는 냉기배출덕트(36)를 통해 외부로 배기된다.An exhaust fan 38 is installed in the cooling device 30 to allow cooling air to flow through the cold air inlet duct 34, and the introduced cooling air is supplied to the cold air inlet 12 formed in the frame 10, thereby providing a battery cell ( After cooling the 20, it is discharged to the cold air outlet (14). The discharged air is exhausted to the outside through the cold air discharge duct 36.

그런데 이러한 종래의 라미네이트형 배터리 셀의 고정 구조는 발전 및 충전 상태에 따라 셀의 두께가 변하는 라미네이트형 배터리 셀의 특성을 반영하는 구조가 없어 안정적인 고정이 어려운 문제가 있다.By the way, the conventional fixed structure of the laminated battery cell has a problem that the stable fixing is difficult because there is no structure that reflects the characteristics of the laminated battery cell, the thickness of the cell is changed according to the power generation and charging state.

또한, 종래에는 냉각 구조가 구비되어 있기는 하지만, 배터리 셀의 위치에 따라 냉각 온도에 차이가 커 배터리 셀의 수명이 단축되는 원인이 되었다.In addition, although the cooling structure is conventionally provided, the cooling temperature is largely different depending on the position of the battery cell, which causes the life of the battery cell to be shortened.

본 발명의 목적은 복수의 라미네이트형 배터리 셀을 안정적으로 고정하고 균일하게 냉각할 수 있는 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀을 제공하는 것이다.It is an object of the present invention to provide a laminated battery cell with improved bonding and cooling structure capable of stably fixing and uniformly cooling a plurality of laminated battery cells.

상기와 같은 목적을 달성하기 위하여 본 발명은 배터리 셀과, 상기 배터리 셀의 외측면을 감싸는 박판 형상의 라미네이트부와, 상기 배터리 셀의 길이 방향 양단부에 연결되는 전극이 구비된 라미네이트형 배터리 셀에 있어서, 상기 라미네이트형 배터리 셀은, 상기 라미네이트형 배터리 셀의 형상에 대응하되 상기 라미네이트형 배터리 셀의 두께보다 큰 높이를 갖도록 형성되는 배터리 삽입부와, 상기 전극이 안착되는 전극 안착부가 구비된 배터리 고정부재에 결합되는 것을 특징으로 하는 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀을 제공한다.In order to achieve the above object, the present invention provides a laminated battery cell provided with a battery cell, a laminated laminate portion surrounding the outer surface of the battery cell, and electrodes connected to both ends in the longitudinal direction of the battery cell; The battery module includes a battery insertion part corresponding to a shape of the laminate battery cell, the battery cell being formed to have a height greater than the thickness of the laminate battery cell, and an electrode seating part on which the electrode is seated. Provided is a laminated battery cell having an improved coupling and cooling structure, characterized in that coupled to.

상기 배터리 고정부재는 하면에 길이 방향을 따라 함몰 형성되어 상기 라미네이트형 배터리 셀의 냉각에 이용되는 공기가 유통되는 공기 유통부를 더 포함하는 것을 특징으로 한다.The battery fixing member may further include an air distribution unit in which a bottom surface of the battery fixing member is recessed along a length direction and in which air used for cooling the laminated battery cell is distributed.

상기 배터리 고정부재는 상기 라미네이트형 배터리 셀이 전기적으로 직렬로 연결되도록 적층된 것을 특징으로 한다.The battery fixing member is laminated so that the laminated battery cells are electrically connected in series.

이상 설명한 바와 같이, 본 발명의 일 실시 예에 따른 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀은 충전 또는 방전 시 배터리 셀의 두께가 변하더라도 배터리 셀이 배터리 고정부재를 벗어나지 않아 과도한 가압력에 의한 배터리 셀의 파손을 방지할 수 있는 장점이 있다.As described above, in the laminate battery cell having improved coupling and cooling structure according to an embodiment of the present invention, even when the thickness of the battery cell is changed during charging or discharging, the battery cell does not leave the battery fixing member so that the battery is caused by excessive pressure. There is an advantage that can prevent damage to the cell.

또한, 배터리 셀을 균일하게 냉각할 수 있어 배터리 셀의 수명이 연장되는 효과가 있다.In addition, since the battery cells can be uniformly cooled, there is an effect of extending the life of the battery cells.

이하에서는 첨부 도면을 참조하여 본 발명의 실시 예들에 따른 결합 및 냉각 구조가 개선된 라미네이트형 배터리 셀에 대해 상세히 설명하기로 한다.Hereinafter, a laminate type battery cell having improved coupling and cooling structures according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부된 도 3은 본 발명의 라미네이트형 배터리 셀 및 고정부재를 도시한 분해 사시도이고, 도 4는 도 3의 Z 방향 VIEW에 따른 라미네이트형 배터리 셀을 도시한 단면도이다. 도 5는 본 발명의 라미네이트형 배터리 셀이 적층된 상태를 도시한 단면도이며, 도 6은 본 발명의 라미네이트형 배터리 셀이 적층된 상태를 도시한 측단면도이다.3 is an exploded perspective view illustrating a laminated battery cell and a fixing member of the present invention, and FIG. 4 is a cross-sectional view of the laminated battery cell according to the Z direction view of FIG. 3. 5 is a cross-sectional view illustrating a laminated battery cell of the present invention in a stacked state, and FIG. 6 is a side cross-sectional view illustrating a laminated battery cell of the present invention in a stacked state.

도 3 내지 도 6에 도시된 바와 같이, 본 발명의 일 실시 예에 따른 라미네이트형 배터리 셀(100)은 배터리 고정부재(200)에 삽입되어 적층되고 직렬로 연결되어 사용된다.As shown in Figures 3 to 6, the laminated battery cell 100 according to an embodiment of the present invention is inserted into the battery fixing member 200 is stacked and used in series.

도 3 및 도 4에 도시된 바와 같이, 라미네이트형 배터리 셀(100)은 박형의 배터리 셀(110) 외측면에 얇은 박판 형상의 라미네이트부(120)가 결합되어 감싸는 형태이며, 배터리 셀(110)의 길이 방향 양단부에는 전극(130)이 삽입된다.As shown in FIG. 3 and FIG. 4, the laminate battery cell 100 is a form in which a thin laminate-shaped laminate part 120 is coupled to and wrapped around an outer surface of the thin battery cell 110 and the battery cell 110. Electrodes 130 are inserted at both ends of the longitudinal direction.

도 3에 도시된 바와 같이, 배터리 고정부재(200)에는 배터리 셀(110)의 두께 보다 큰 높이를 갖는 배터리 삽입부(210)가 형성되며, 전극(130)의 위치에 대응하여 길이 방향의 양단부에 전극 안착부(220)가 형성된다.As shown in FIG. 3, a battery insertion unit 210 having a height greater than the thickness of the battery cell 110 is formed in the battery fixing member 200, and both ends in the longitudinal direction corresponding to the position of the electrode 130 are provided. The electrode seating portion 220 is formed.

배터리 삽입부(210) 및 전극 안착부(220)에 맞추서 라미네이트형 배터리 셀(100)이 삽입되면 라미네이트형 배터리 셀(100)이 충전 및 방전시 두께가 변화되더라도 배터리 삽입부(210)의 높이가 라미네이트형 배터리 셀(100)의 높이보다 크므로, 라미네이트형 배터리 셀(100)이 배터리 고정부재(200) 밖으로 돌출되지 않는다.When the laminated battery cell 100 is inserted in accordance with the battery inserting part 210 and the electrode seating part 220, the height of the battery inserting part 210 may be changed even when the laminated battery cell 100 is changed in thickness during charging and discharging. Since the laminated battery cell 100 is greater than the height of the laminated battery cell 100, the laminated battery cell 100 does not protrude out of the battery fixing member 200.

따라서 라미네이트형 배터리 셀(100)의 적층시 과도한 적층 압력이 가해지지 않아 라미네이트형 배터리 셀(100)의 외장인 라미네이트부(120)의 파손을 방지할 수 있다.Accordingly, excessive lamination pressure is not applied when the laminate battery cells 100 are stacked, thereby preventing damage to the laminate 120 that is an exterior of the laminate battery cells 100.

한편, 배터리 고정부재(200)의 하면에는 길이 방향을 따라 공기 유통부(230)가 함몰 형성된다.On the other hand, the lower surface of the battery fixing member 200 is formed in the air distribution unit 230 along the longitudinal direction.

공기 유통부(230)는 라미네이트형 배터리 셀(100)을 냉각하기 위한 공기(냉각풍)가 유입되어 라미네이트형 배터리 셀(100)을 냉각한 후 배출되는 통로가 되며, 균일한 냉각 성능을 위해 배터리 고정부재(200)는 직렬로 적층되는 것이 바람직하다.The air distribution unit 230 is a passage through which air (cooling air) for cooling the laminated battery cell 100 is introduced and cooled after cooling the laminated battery cell 100, and the battery is discharged for uniform cooling performance. The fixing member 200 is preferably stacked in series.

도 5 및 도 6에 도시된 바와 같이, 배터리 고정부재(200)는 공기 유통부(230)가 수직으로 일렬로 배치되도록 적층되며, 라미네이트형 배터리 셀(100)은 전기적으로 직렬로 연결된다.As shown in FIGS. 5 and 6, the battery fixing members 200 are stacked such that the air distributors 230 are vertically arranged in a row, and the laminated battery cells 100 are electrically connected in series.

라미네이트형 배터리 셀(100)의 두께가 변하더라도 배터리 고정부재(200) 밖 으로 돌출되지 않으므로 직렬로 적층된 상태에서도 안정적으로 적층 상태를 유지할 수 있게 된다.Even if the thickness of the laminate type battery cell 100 changes, the battery fixing member 200 does not protrude out of the stack, so that the stacking state can be stably maintained.

배터리 고정부재(200)가 적층된 상태에서 냉각을 위한 공기는 공기 유통부(230)의 일측으로 흡기되어 라미네이트형 배터리 셀(100)을 냉각한 후 타측으로 배기된다. 배터리 고정부재(200)의 적층 수는 라미네이트형 배터리 셀(100)의 사용 매수에 대응하며, 배터리 고정부재(200)는 적층된 배터리 고정부재(200)들 전체를 관통하는 홀을 구비하여 볼트 등으로 고정하거나 종래와 마찬가지로 적층된 배터리 고정부재(200) 전체를 수납하는 케이스 등을 이용할 수도 있다.Air for cooling in the state in which the battery fixing member 200 is stacked is intake to one side of the air distribution unit 230 to cool the laminated battery cell 100 and then exhausted to the other side. The stacking number of the battery fixing member 200 corresponds to the number of sheets of the laminated battery cell 100, and the battery fixing member 200 has a hole penetrating the entire stacked battery fixing members 200, and the like. Or a case for storing the entire battery fixing member 200 stacked as in the prior art.

또한, 배터리 고정부재(200)를 적층하지 않고 횡방향으로 배치하는 것도 가능하다.In addition, the battery fixing members 200 may be disposed in the lateral direction without being stacked.

예를 들어, 종래의 배터리 셀(20)을 24매 병렬로 배치 후 적층한 상태에서 냉매배출덕트(36)에 인접한 배터리 셀(20)의 최대 온도는 50℃이고, 냉매유입덕트(34)에 인접한 배터리 셀(20)의 최저 온도는 41℃로, 최대 온도차는 9℃로 배터리 셀(20)의 수명은 6년 정도로 예상된다.For example, the maximum temperature of the battery cell 20 adjacent to the refrigerant discharge duct 36 is 50 ° C. in the state where the conventional battery cells 20 are arranged in parallel after 24 sheets are stacked in the refrigerant inlet duct 34. The minimum temperature of the adjacent battery cells 20 is 41 ° C., the maximum temperature difference is 9 ° C., and the life of the battery cells 20 is expected to be about 6 years.

반면, 본 발명의 라미네이트형 배터리 셀(100)을 24매 직렬로 적층하여 사용하는 경우 라미네이트형 배터리 셀(100)의 최대 온도는 46℃이고 최저 온도는 42℃로 최대 온도차는 4℃에 불과하며, 라미네이트형 배터리 셀(100)의 기대 수명은 10년 정도로 예측된다.On the other hand, when the laminated battery cells 100 of the present invention are stacked in series of 24 sheets, the maximum temperature of the laminated battery cell 100 is 46 ° C., the minimum temperature is 42 ° C., and the maximum temperature difference is only 4 ° C. The life expectancy of the laminated battery cell 100 is estimated to be about 10 years.

따라서 본 발명의 적층 및 냉각 구조를 적용하는 경우 배터리 셀의 기대 수명이 증가되고, 고정 부재의 구조가 단순하여 제조 원가를 절감하는 효과가 있다.Therefore, when applying the stacking and cooling structure of the present invention, the life expectancy of the battery cell is increased, and the structure of the fixing member is simple, thereby reducing the manufacturing cost.
