이차전지는 휴대폰, 노트북, 캠코더 등 모바일 기기들의 전원으로 널리 사용되고 있다. 특히, 리튬 이차전지의 사용은 작동전압이 높고, 단위 중량당 에너지밀도가 높다는 잇점으로 인해 급속도로 증가되고 있는 추세이다. Secondary batteries are widely used as power sources for mobile devices such as mobile phones, notebooks, and camcorders. In particular, the use of lithium secondary batteries is rapidly increasing due to the advantage of high operating voltage and high energy density per unit weight.

이러한 리튬 이차전지는 전극과 전해액의 구성에 따라 리튬이온 전지, 리튬이온 폴리머 전지, 리튬 폴리머 전지 등으로 분류되기도 하며, 그 중 전해액의 누액 가능성이 적으며, 제조가 용이한 리튬이온 폴리머 전지의 사용량이 늘어나고 있다. 리튬이온 폴리머 전지(LiPB)는 전극(양극 및 음극)과 분리막을 열융착시킨 전극조립체에 전해액을 함침시킨 구조로서, 주로 스택형 전극조립체 또는 스택/폴딩형 전극조립체를 알루미늄 라미네이트 시트의 파우치형 케이스에 밀봉한 형태로서 많이 사용되고 있다. 따라서, 리튬이온 폴리머 전지를 종종 파우치형 전지로 칭하기도 한다.Such a lithium secondary battery may be classified as a lithium ion battery, a lithium ion polymer battery, or a lithium polymer battery depending on the configuration of an electrode and an electrolytic solution. The lithium secondary battery is less liable to leak electrolyte, Is increasing. The lithium ion polymer battery (LiPB) is a structure in which an electrode assembly (electrode and anode) and a separator are thermally fused to each other and an electrolytic solution is impregnated into the electrode assembly. The stacked electrode assembly or the stack / Is often used as a sealed form. Therefore, a lithium ion polymer battery is often referred to as a pouch type battery.

도 1에는 스택형 전극조립체를 포함하고 있는 대표적인 파우치형 전지의 일반적인 구조가 모식적으로 도시되어 있다.FIG. 1 schematically shows a general structure of a typical pouch-type battery including a stacked electrode assembly.

이들 도면을 참조하면, 파우치형 전지(10)는, 파우치형의 전지케이스(20) 내부에 양극, 음극 및 이들 사이에 배치되는 분리막으로 이루어진 전극조립체(30)가 내장되어 있고, 그것의 양극 및 음극 탭들(31, 32)이 두 개의 전극리드(40, 41)에 용접되어 전지케이스(20)의 외부로 노출되도록 실링(밀봉)되어 있는 구조로 이루어져 있다. Referring to these drawings, the pouch-shaped battery 10 has an electrode assembly 30 including a positive electrode, a negative electrode, and a separator disposed therebetween in a pouch-shaped battery case 20, The negative electrode tabs 31 and 32 are welded to the two electrode leads 40 and 41 and sealed (sealed) so as to be exposed to the outside of the battery case 20.

전지케이스(20)는 알루미늄 라미네이트 시트와 같은 연포장재로 되어 있으며, 전극조립체(30)가 안착될 수 있는 오목한 형상의 수납부(23)를 포함하는 케이스 본체(21)와 그러한 본체(21)에 일측이 연결되어 있는 덮개(22)로 이루어져 있다. The battery case 20 is made of a soft packaging material such as an aluminum laminate sheet and includes a case body 21 including a concave shaped storage portion 23 on which the electrode assembly 30 can be seated, And a lid 22 to which one side is connected.

이러한 파우치형 전지(10)는 수납부(23)에 전극조립체(30)를 안착한 후 덮개(22)를 덮고 본체(21)과의 접촉 부위를 열융착시켜 밀봉한다. This pouch-shaped battery 10 seals the electrode assembly 30 on the housing portion 23, covers the lid 22, and seals the contact portion with the main body 21 by heat fusion.

그 후, 전지케이스(20)의 강성 및 평탄도를 개선하기 위하여 고온 상태에서 가압하는 공정을 통해 파우치형 전지를 제조한다.Thereafter, in order to improve the rigidity and flatness of the battery case 20, a pouch-shaped battery is manufactured through a process of pressing at a high temperature.

도 2에는 종래의 고온 가압 공정에 관한 모식도들이 도시되어 있다. FIG. 2 is a schematic view of a conventional high temperature pressurizing process.

도 2를 참조하면, 다수의 전지셀들(10) 사이에 각각 금속 플레이트들(60)을 개재한 상태에서 지그(70)에 장착한 후 가압부(80)에 의해 전지셀들(10)을 가압하는 과정이 나타나 있으며, 이러한 상태에서 챔버(90) 내에서 히터(92)에 의해 가열되는 구조로 이루어져 있다. Referring to FIG. 2, after the metal plates 60 are interposed between the plurality of battery cells 10, the battery cells 10 are attached to the jig 70 by the pressing portion 80, And is heated by the heater 92 in the chamber 90 in this state.

그러나, 상기와 같은 종래의 고온 가압 공정은 히터(92)를 포함하는 챔버(90)의 제조비용이 높고, 히터(92)의 열이 챔버(90) 내의 공기를 통해 전지셀들(10)에 전달되므로 열 전달 효율이 좋지 않을 뿐 만 아니라, 승온 시간이 길어지게 되므로 에너지 소비가 증가하여 비용이 상승한다는 단점이 있다. 또한, 안전성을 위하여 방화 설비가 요구되며, 이로 인해 챔버(90)를 포함하는 설비의 부피가 더욱 커지게 되는 문제점이 유발된다. However, in the conventional high temperature pressurizing process, the manufacturing cost of the chamber 90 including the heater 92 is high, and the heat of the heater 92 is transmitted to the battery cells 10 through the air in the chamber 90 The heat transfer efficiency is not good, and the temperature rise time becomes long. Therefore, the energy consumption increases and the cost increases. In addition, fire protection equipment is required for safety, thereby causing a problem that the volume of the facility including the chamber 90 becomes larger.

따라서, 이러한 문제점들을 근본적으로 해소하면서 전지셀의 고온 가압 공정에 대한 비용을 절감하고 보다 간단한 과정으로 효율적으로 전지셀에 대해 고온 가압을 수행하는 기술에 대한 필요성이 높은 실정이다.Accordingly, there is a high need for a technique for effectively reducing the cost of the high-temperature pressurization process of the battery cell and performing the high-temperature pressurization on the battery cell in a simpler process while fundamentally eliminating these problems.

본 발명은 상기와 같은 종래기술의 문제점과 과거로부터 요청되어온 기술적 과제를 해결하는 것을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems of the prior art and the technical problems required from the past.

따라서, 본 발명의 목적은, 전지셀의 고온 가압 공정에 필요한 장치를 간소화 하고, 열 전달 효율을 상승시켜 에너지 비용을 절감할 수 있는 전지셀 고온 가압 장치을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a battery cell high-temperature pressurizing apparatus which can simplify the apparatus necessary for the high-temperature pressurization process of the battery cell and increase the heat transfer efficiency and reduce the energy cost.

이러한 목적을 달성하기 위한 본 발명에 따른 전지셀 고온 가압 장치는, According to an aspect of the present invention, there is provided a battery cell high-

둘 이상의 전지셀들을 고온 상태에서 가압하여 전지셀들의 강성 및 평탄도를 개선하는 가압 장치로서, 1. A pressurizing apparatus for pressurizing two or more battery cells at a high temperature to improve rigidity and flatness of the battery cells,

다수의 전지셀들이 탑재되는 지그 본체;A jig main body on which a plurality of battery cells are mounted;

각각의 전지셀들의 계면에 개재되는 발열 플레이트들; 및Heat generating plates interposed in an interface between the respective battery cells; And

상기 전지셀들 사이에 발열 플레이트들이 개재된 상태로 적층 배열된 구조의 적층 방향 최외부를 가압하는 가압부;A pressing portion for pressing the outermost layer in the stacking direction of the structure in which the heating plates are interposed between the battery cells;

를 포함하는 구조로 구성될 수 있다.As shown in FIG.

즉, 본 발명에 따른 전지셀 고온 가압 장치는 히터를 포함하는 고온 챔버를 사용하지 않고, 전지셀들의 계면에 발열 플레이트를 개재하여 고온을 인가하면서 가압부에 의해 가압하는 구조로 형성될 수 있다. 상기 발열 플레이트에서 전지셀이 접하는 면은 평면으로 형성되어 있어서, 전지셀에 고온을 인가하면서, 가압부에 의한 압력으로 전지셀을 평탄화하는 구조로 형성될 수 있다. That is, the battery cell high-temperature biasing apparatus according to the present invention can be formed in a structure in which a high-temperature chamber is pressed through a heat generating plate while applying a high temperature to an interface of battery cells without using a high-temperature chamber including a heater. The surface of the heat generating plate, which is in contact with the battery cells, is formed in a flat surface, and the battery cells may be flattened by applying pressure to the battery cells while applying a high temperature to the battery cells.

따라서, 본 발명에 따른 전지셀 고온 가압 장치는 고온 챔버를 생략할 수 있으므로 이에 관한 비용을 절감할 수 있고, 공간을 적게 차지하는 효과가 있다. Therefore, the battery cell high-temperature pressurizing apparatus according to the present invention can omit the high-temperature chamber, so that it is possible to reduce the cost of the high-temperature chamber and to have a space-saving effect.

또한, 열 전달 경로가 짧아서 열 전달 효율이 상승하고, 이에 따라 에너지 비용을 절감할 수 있다. In addition, the heat transfer path is short and the heat transfer efficiency is increased, thereby reducing the energy cost.

상기 발열 플레이트들은 전지셀이 접하는 면이 평면으로 형성되어 있는 판상형의 플레이트로서, 발열 구조로 이루어질 수 있다. 하나의 예로, 상기 발열 플레이트들은 금속 소재로 형성될 수 있으며, 상기 금속 소재는 알루미늄 또는 알루미늄 합금일 수 있으나, 이에 한정되지 않고 다양한 금속이 사용될 수 있다. The heat generating plates may be plate-shaped plates having a flat surface in contact with the battery cells, and may have a heat generating structure. As one example, the heating plates may be formed of a metal material, and the metal material may be aluminum or an aluminum alloy, but not limited thereto, various metals may be used.

상기 발열 플레이트의 발열은 예를 들어 플레이트 내에 열선이 내장된 구조로써 달성될 수 있다. 이러한 발열 플레이트는 섭씨 30도 내지 섭씨 100도의 온도로 가열되어 전지셀들에 열을 인가하는 구조로 이루어질 수 있다. 발열 플레이트의 온도가 너무 낮으면 전지셀의 평탄화 및 강성을 향상시키기 어렵고, 반대로 너무 높으면 전지셀 케이스가 용융되거나 연소되므로 바람직하지 않다. 상기 발열 플레이트의 적정 온도는 전지셀 케이스의 소재, 두께, 또는 가열 진행 경과 시간 등에 의해 조절될 수 있음은 물론이다. The heat generation of the heat generating plate can be achieved, for example, with a structure in which heat rays are embedded in the plate. The heat generating plate may be heated to a temperature of 30 to 100 degrees Celsius to apply heat to the battery cells. If the temperature of the heat generating plate is too low, it is difficult to improve the planarization and rigidity of the battery cell. On the other hand, if the temperature is too high, the battery cell case is not melted or burned. It is a matter of course that the proper temperature of the heating plate can be controlled by the material, the thickness, the elapsed time of heating, and the like of the battery cell case.

상기 지그 본체는, 예를 들어 전지셀들 사이에 발열 플레이트가 개재된 구조가 안착되도록 상부가 개방된 중공형 구조로 형성될 수 있으며, 일측 벽에 상기 가압부가 장착될 수 있다. 즉, 상기 지그 본체의 일측 벽 의 대향측 벽과 상기 가압부 사이에 방열 플레이트들이 개재된 전지셀들이 장착된 상태에서, 상기 가압부에 의해 전지셀들이 가압되는 구조로 이루어질 수 있다. For example, the jig body may be formed in a hollow structure having an open top so that a structure in which a heat generating plate is interposed between battery cells, and the pressing portion may be mounted on one side wall. That is, the battery cells may be pressed by the pressing portion in a state in which the battery cells having the heat dissipation plates interposed between the opposing side walls of the jig body and the pressing portion are mounted.

상기 전지셀은, 예를 들어, 판상형의 파우치형 케이스에 전극조립체가 내장되어 있는 파우치형 전지셀일 수 있지만, 그것 만으로 한정되는 것은 아니다.The battery cell may be, for example, a pouch-shaped battery cell in which an electrode assembly is embedded in a pouch-shaped case of a plate-like shape, but is not limited thereto.

상기 파우치형 전지셀은, 구체적으로, 수지층과 금속층을 포함하는 라미네이트 시트의 전지케이스에 전극조립체가 전지케이스의 외부로 돌출된 전극단자들과 연결된 상태로 내장되어 있는 구조일 수 있다.Specifically, the pouch-shaped battery cell may have a structure in which an electrode assembly is embedded in a battery case of a laminate sheet including a resin layer and a metal layer in a state of being connected to electrode terminals projected to the outside of the battery case.

한편, 전지셀의 제조과정에서는 전극조립체가 내장된 전지케이스에 전해액을 주입한 후 충전과 방전을 수행하는 전지셀 활성화 과정이 포함된다. 이러한 전지셀 활성화 과정에서는 충방전시 발생하는 가스 및 잉여 전해액을 제거하는 공정이 추가로 진행된다. The battery cell manufacturing process includes a battery cell activation process in which an electrolyte is injected into a battery case having an electrode assembly, followed by charging and discharging. In the battery cell activation process, a process for removing gas and excess electrolyte generated during charging and discharging is further performed.

따라서, 본 발명의 전지셀 고온 가압 장치를 사용하여 전지셀을 평탄화하고 강도를 향상시키는 과정에서는, 상기의 가스 및 잉여 전해액을 제거하는 과정을 동시에 진행할 수 있다. 이러한 경우, 상기 파우치형 전지셀은 전지케이스에 전극조립체를 장착한 상태에서 충전과 방전을 수행하는 활성화 과정을 수행한 전지셀로서, 활성화 과정에서 발생한 가스와 잉여 전해액을 제거하기 전 단계의 전지셀일 수 있다.Accordingly, in the process of flattening the battery cell and improving the strength of the battery cell using the high-temperature battery cell high-temperature pressurizing apparatus, the process of removing the gas and the surplus electrolyte can be performed at the same time. In this case, the pouch-shaped battery cell is a battery cell in which an activation process is performed to perform charging and discharging while the electrode assembly is mounted on the battery case, .

즉, 전지셀의 활성화시 발생한 가스 및 잉여 전해액의 제거를 위하여 별도의 제거 공정을 거치고 있으나, 본 발명의 전지셀 고온 가압 장치에서는, 전지셀을 고온 가압하는 과정에서 상기 가스 제거 및 잉여 전해액 제거 과정을 동시에 진행할 수 있으므로 제조 공정을 단순화할 수 있다. That is, in order to remove the gas generated during the activation of the battery cell and the surplus electrolyte, a separate removal process is performed. However, in the battery cell high temperature depressurization apparatus, in the process of pressurizing the battery cell at high temperature, So that the manufacturing process can be simplified.

상기 전지셀은 리튬이온 전지 또는 리튬이온 폴리머 전지셀일 수 있지만, 이들만으로 한정되지 않음은 물론이다.The battery cell may be a lithium ion battery or a lithium ion polymer battery cell, but is not limited thereto.

본 발명은 또한, 상기 전지셀 고온 가압 장치를 사용하여 제조된 전지셀을 제공한다.The present invention also provides a battery cell manufactured using the battery cell high-temperature pressurizing apparatus.

본 발명은 또한, 상기 전지셀을 전원으로 포함하고 있는 디바이스를 제공하는 바, 상기 디바이스는 휴대폰, 휴대용 컴퓨터, 스마트폰, 태플릿 PC, 스마트 패드, 넷북, LEV(Light Electronic Vehicle), 전기자동차, 하이브리드 전기자동차, 플러그-인 하이브리드 전기자동차, 및 전력저장장치로 이루어진 군에서 선택되는 것일 수 있다.The present invention also provides a device comprising the battery cell as a power source, wherein the device is used in a mobile phone, a portable computer, a smart phone, a tablet PC, a smart pad, a netbook, a LEV (Light Electronic Vehicle) A hybrid electric vehicle, a plug-in hybrid electric vehicle, and a power storage device.

이들 디바이스의 구조 및 그것의 제작 방법은 당업계에 공지되어 있으므로, 본 명세서에서는 그에 대한 자세한 설명은 생략한다.The structure of these devices and their fabrication methods are well known in the art, and a detailed description thereof will be omitted herein.

본 발명은 또한, 전지셀 고온 가압 장치를 사용하여 전지셀을 고온 상태에서 가압하는 방법을 제공하며, 이러한 과정의 하나의 예를 들면 다음과 같다. The present invention also provides a method of pressurizing a battery cell at a high temperature using a battery cell high-temperature pressurizing apparatus. One example of such a process is as follows.

먼저 전지셀들 사이에 발열 플레이트들을 개재하여 적층 배열된 구조를 형성시키고, 이를 지그 본체에 장착한다. 그 후, 적층 배열된 구조의 최외곽에 위치한 전지셀을 가압부로 가압한 다음, 발열 플레이트의 온도를 상승시킨다. 소정의 시간이 지난 후 발열 플레이트의 온도를 하강시키고, 가압부의 가압을 해지하여 고온 가압 처리된 전지셀을 분리해 낸다. First, a structure in which battery cells are laminated and arranged with heating plates interposed therebetween is formed, and the structure is mounted on the jig main body. Thereafter, the battery cell located at the outermost of the laminated structure is pressed by the pressing portion, and then the temperature of the heat generating plate is raised. After a predetermined time has elapsed, the temperature of the heat generating plate is lowered and the pressurization of the pressurizing portion is released to separate the battery cells subjected to high temperature pressurization.

이상에서 설명한 바와 같이, 본 발명에 따른 전지셀 고온 가압 장치는, 고온 챔버를 사용하지 않고 발열 플레이트를 사용하여 고온 가압 공정을 수행하므로, 고온 챔버에 비용을 절감할 수 있고, 공간을 적게 차지하며, 열 전달 경로가 짧아서 열 전달 효율이 우수하고, 이에 따라 에너지 비용을 절감할 수 있는 효과가 있다. As described above, the battery cell high-temperature pressurizing apparatus according to the present invention performs a high-temperature pressurizing process using a heat-generating plate without using a high-temperature chamber, so that it is possible to save costs in a high-temperature chamber, , The heat transfer path is short so that the heat transfer efficiency is excellent and the energy cost can be reduced accordingly.
