본 발명은 애노드(Anode)의 구조를 개선한 리튬/염화티오닐 전지에 관한 것이다.The present invention relates to a lithium / thionyl chloride battery having an improved structure of an anode.

도 1은 종래의 리튬/염화티오닐 전지의 애노드(Anode)의 사시도로서, 이를 설명한다.1 is a perspective view of an anode of a conventional lithium / thionyl chloride battery, which will be described.

도시된 바와 같이, 애노드(Anode)(10)는 망 형태인 금속제의 집전체(11)와 집전체(11)의 일면 및 타면에 코팅된 활물질인 리튬(Li)층(13)(15)과 집전체(11)의 일면에 접속 설치되며 양단부측이 집전체(11)의 외측으로 노출된 리드(Lead)(17)를 가진다.As shown in the drawing, the anode 10 includes a metal current collector 11 having a mesh form and lithium (Li) layers 13 and 15 which are active materials coated on one and the other surfaces of the current collector 11. It is connected to one surface of the current collector 11 and has both ends 17 having leads 17 exposed to the outside of the current collector 11.

애노드(10)와 캐소드(Cathode)(미도시)는 격리막(미도시)에 의하여 구획되어 롤 형태로 감겨서 케이스(미도시)의 내부에 설치되고, 상기 케이스의 내부에는 전해액인 염화티오닐(SOCl2)이 주입되어 리튬/염화티오닐 전지를 구성한다. 그리하여, 부하가 인가되면 상기 전해액과 전극의 산화 환원 반응에 의해 화학에너지가 전기에너지로 변환되어 에너지인 전류를 발생한다.The anode 10 and the cathode (not shown) are partitioned by a separator (not shown) and wound in a roll to be installed inside the case (not shown). SOCl 2 ) is injected to constitute a lithium / thionyl chloride cell. Thus, when a load is applied, chemical energy is converted into electrical energy by the redox reaction of the electrolyte and the electrode to generate a current that is energy.

리튬층(13)(15)은 상기 케이스의 내부에 주입된 상기 전해액과 반응하여 에너지를 생성하고, 집전체(11)는 생성된 전자를 모음과 동시에 전기화학반응에 필요한 전자를 공급하며, 리드(17)는 리튬/염화티오닐 전지의 음극단자측과 접속된다.The lithium layers 13 and 15 react with the electrolyte injected into the case to generate energy, and the current collector 11 collects the generated electrons and simultaneously supplies electrons required for the electrochemical reaction. 17 is connected to the negative terminal side of a lithium / thionyl chloride battery.

상호 전기화학반응을 하는 리튬층(13)(15)과 상기 전해액은 사용함에 따라 소모된다. 그런데, 리튬/염화티오닐 전지는 방전 말기에 상기 전해액이 상기 캐소드의 활물질 역할을 한다. 이로인해, 리튬층이 완전히 소진되었음에도 불구하고, 방전이 진행되면서 상기 전해액은 고갈되고 그 부산물로 황이 생성된다. 그러면, 리튬/염화티오닐 전지의 내부가 건조되므로, 내부단락이나 비가역적 화학반응 등과 같은 이상 발생시 과열에 의한 안전사고가 발생할 우려가 있다.The lithium layers 13 and 15 and the electrolyte, which perform mutual electrochemical reactions, are consumed as they are used. However, in a lithium / thionyl chloride battery, the electrolyte serves as an active material of the cathode at the end of discharge. As a result, although the lithium layer is completely exhausted, as the discharge proceeds, the electrolyte is depleted and sulfur is produced as a by-product. Then, since the inside of the lithium / thionyl chloride battery is dried, there is a fear that a safety accident due to overheating may occur when an abnormality such as an internal short circuit or irreversible chemical reaction occurs.

이를 방지하기 위하여 리튬층(13)(15)의 용량 비율 대비 약 1.1∼1.2배의 전해액을 상기 케이스에 주입하여, 리튬층(13)(15)이 완전히 소진된 경우에도 상기 전해액이 잔존하도록 하였으나, 안전사고의 완전한 방지에는 미흡하다.In order to prevent this, about 1.1 to 1.2 times the electrolyte ratio of the capacity ratio of the lithium layers 13 and 15 was injected into the case so that the electrolyte remained even when the lithium layers 13 and 15 were completely exhausted. The lack of complete prevention of safety accidents.

완전한 안전사고의 방지를 위해서는 상기 케이스의 내부에 상기 전해액을 더 많이 주입하면 되나, 상기 케이스의 크기는 제한되어 있으므로 상기 전해액을 상기 케이스에 더 많이 주입할 수 없는 단점이 있다.In order to prevent a complete safety accident, more of the electrolyte may be injected into the inside of the case. However, since the size of the case is limited, more of the electrolyte may not be injected into the case.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 전해액의 고갈을 방지하여 안전사고를 완전히 예방할 수 있는 리튬/염화티오닐 전지를 제공함에 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a lithium / thionyl chloride battery that can completely prevent a safety accident by preventing the exhaustion of the electrolyte.

상기 목적을 달성하기 위한 본 발명에 따른 리튬/염화티오닐 전지는, 전해액이 주입된 케이스, 집전체와 상기 집전체의 일면과 타면에 코팅된 리튬층과 상기 집전체에 접속된 리드(Lead)를 가지는 애노드(Anode)와 캐소드(Cathode)를 가지면서 상기 케이스에 설치된 전극, 상기 애노드와 상기 캐소드를 격리하는 격리막을 포함하는 리튬/염화티오닐 전지에 있어서, 상기 집전체의 일면과 타면 중, 적어도 한 면의 일부는 리튬이 코팅되지 않으며, 상기 리드가 상기 집전체의 일면에 접속되고 상기 집전체의 타면이 상기 캐소드와 대향 한다고 가정할 때, 상기 리드가 위치된 상기 집전체의 타면 부위는 리튬이 코팅되고, 그 이외의 상기 집전체의 타면 부위는 리튬이 코팅되지 않는 것이다.Lithium / thionyl chloride battery according to the present invention for achieving the above object, a case in which the electrolyte is injected, a current collector and a lithium layer coated on one side and the other side of the current collector and the lead connected to the current collector In the lithium / thionyl chloride battery comprising an electrode having an anode (Anode) having a cathode and a cathode (Cathode), the separator isolating the anode and the cathode, the one side and the other side of the current collector, At least part of one side is not coated with lithium, and assuming that the lead is connected to one side of the current collector and the other side of the current collector faces the cathode, the other side portion of the current collector on which the lead is placed is Lithium is coated, and the other surface portion of the current collector other than that is not coated with lithium.

이하, 첨부된 도면을 참조하여 본 발명의 일 실시예에 따른 리튬/염화티오닐 전지를 상세히 설명한다.Hereinafter, a lithium / thionyl chloride battery according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 리튬/염화티오닐 전지의 일부 절개 사시도이다.2 is a partially cutaway perspective view of a lithium / thionyl chloride battery according to an embodiment of the present invention.

도시된 바와 같이, 본 실시예에 따른 리튬/염화티오닐 전지는 전해액인 염화티오닐(SOCl2)이 주입된 케이스(110)를 가진다.As shown, the lithium / thionyl chloride battery according to the present embodiment has a case 110 in which thionyl chloride (SOCl 2 ), which is an electrolyte, is injected.

케이스(110)의 내부에는 판 형태의 애노드(Anode)(130)와 판 형태의 캐소드(Cathode)(140)를 가지는 전극이 롤 형태로 감겨서 설치되고, 애노드(130)와 캐소드(140)는 절연체인 격리막(150)에 의하여 격리된다. 격리막(150)은 애노드(130)와 캐소드(140) 사이에 개재되어 애노드(130) 및 캐소드(140)와 동일한 형태로 감긴다. 이때, 격리막(150)은 외곽에 위치된 캐소드(140)의 외면에도 감길 수 있다.Inside the case 110, an electrode having a plate-shaped anode 130 and a plate-shaped cathode 140 is wound and installed in a roll shape, and the anode 130 and the cathode 140 are It is isolated by the insulating film 150 which is an insulator. The separator 150 is interposed between the anode 130 and the cathode 140 to be wound in the same form as the anode 130 and the cathode 140. In this case, the separator 150 may also be wound on the outer surface of the cathode 140 located at the outer side.

그리하여, 부하가 인가되면 상기 전해액과 상기 전극의 산화 환원 반응에 의해 화학에너지가 전기에너지로 변환되어 에너지인 전류를 발생한다.Thus, when a load is applied, chemical energy is converted into electrical energy by the redox reaction of the electrolyte and the electrode to generate a current that is energy.

상호 전기화학반응을 하는 상기 전해액과 애노드(130)의 리튬층(133)(135)(도 3a 및 도 3b참조)은 사용함에 따라 소모되고, 상기 전해액이 고갈됨에 따라 과열에 의한 안전사고가 발생할 우려가 있다.Lithium layers 133 and 135 (see FIGS. 3A and 3B) of the electrolyte and the anode 130 which perform mutual electrochemical reactions are consumed as they are used, and safety accidents due to overheating may occur as the electrolyte is depleted. There is concern.

본 실시예에 따른 리튬/염화티오닐 전지는 상기 전해액이 고갈되는 것을 방지할 수 있는 구조로 마련되는데, 이를 도 2 내지 도 3b를 참조하여 설명한다. 도 3a 및 도 3b는 본 발명의 일 실시예에 따른 애노드(Anode)의 일면 및 타면을 보인 사시도이다.The lithium / thionyl chloride battery according to the present embodiment has a structure that can prevent the electrolyte from being depleted, which will be described with reference to FIGS. 2 and 3B. 3A and 3B are perspective views illustrating one side and the other side of an anode according to an embodiment of the present invention.

도시된 바와 같이, 애노드(130)는 망 형상으로 마련되며 생성된 전자를 모음과 동시에 전기화학반응에 필요한 전자를 공급하는 집전체(131), 집전체(131)의 일면 및 타면에 코팅되며 상기 전해액과 반응하여 에너지를 생성하는 리튬 층(133)(135), 집전체(131)에 접속되며 양단부측은 집전체(131)의 외측으로 노출되어 케이스(110)측에 형성된 음극단자(미도시)와 접속되는 리드(Lead)(138)를 가진다.As shown, the anode 130 is provided in a mesh shape and is coated on one side and the other side of the current collector 131, the current collector 131 for supplying the electrons required for the electrochemical reaction at the same time the generated electrons Cathode terminals (not shown) connected to the lithium layers 133 and 135 and the current collector 131 that react with the electrolyte to generate energy, and both ends are exposed to the outside of the current collector 131. It has a lead (138) connected with.

이때, 집전체(131)의 일면 및 타면 중, 적어도 한 면의 일부는 리튬이 코팅되지 않고 외부로 노출된다.At this time, at least one of one surface and the other surface of the current collector 131 is exposed to the outside without lithium coating.

상세히 설명하면, 격리막(150)을 사이에 두고 애노드(130)와 캐소드(140)를 배치하였을 때, 도 3a에 도시된 바와 같이, 집전체(131)의 일면에 리드(138)가 접속되고, 도 3b에 도시된 바와 같이, 집전체(131)의 타면이 캐소드(140)와 대향한다고 가정한다.In detail, when the anode 130 and the cathode 140 are disposed with the separator 150 interposed therebetween, as shown in FIG. 3A, the lead 138 is connected to one surface of the current collector 131. As shown in FIG. 3B, it is assumed that the other surface of the current collector 131 faces the cathode 140.

이때, 도 3b에 도시된 바와 같이, 캐소드(140)와 대향하는 집전체(131)의 타면 부위 중, 리드(138)기 위치되는 집전체(131)의 타면 부위는 리튬이 코팅되어 캐소드(140)와의 접속을 더욱 방지하고, 그 이외의 집전체(131)의 타면 부위는 리튬이 코팅되지 않는다. 그리고, 도 3a에 도시된 바와 같이, 리드(138)가 접속된 집전체(131)의 일면 부위는 중, 리드(138)가 접속된 집전체(131)의 일면 부위는 리튬이 코팅되지 않고, 그 이외의 집전체(131)의 일면 부위는 리튬이 코팅된다.In this case, as shown in FIG. 3B, of the other surface portion of the current collector 131 facing the cathode 140, the other surface portion of the current collector 131 in which the lead 138 is located is coated with lithium to form the cathode 140. ) Is further prevented, and the other surface portion of the current collector 131 other than that is not coated with lithium. 3A, one surface portion of the current collector 131 to which the lead 138 is connected is not coated with lithium on one surface portion of the current collector 131 to which the lead 138 is connected. One side of the current collector 131 other than that is coated with lithium.

즉, 집전체(131)의 일면 및 타면에 형성된 리튬이 코팅되지 않은 부위는 상호 어긋나게 형성된다.That is, the portions of the current collector 131 that are not coated with lithium formed on one surface and the other surface of the current collector 131 are alternately formed.

그러면, 집전체(131)에 형성되는 리튬층(133)(135)의 부피가 작아지므로, 리튬층(133)(135)이 형성되지 않은 공간에 해당하는 만큼, 상기 전해액을 케이스(110)의 내부에 더 많이 주입할 수 있다. 그러므로, 본 실시예에 따른 리튬/염 화티오닐 전지는 리튬층(133)(135)이 완전히 소진되어도, 상기 전해액이 케이스(110)의 잔존한다.Then, since the volume of the lithium layers 133 and 135 formed on the current collector 131 is reduced, the electrolyte may be transferred to the case 110 as much as it corresponds to the space where the lithium layers 133 and 135 are not formed. More can be injected inside. Therefore, in the lithium / thionyl chloride battery according to the present embodiment, even when the lithium layers 133 and 135 are completely exhausted, the electrolyte remains in the case 110.

리튬층(133)(135)이 형성되지 않는 부위의 폭 및 개수는 사양에 따라 적절하게 조절하면 된다.The width and number of portions where the lithium layers 133 and 135 are not formed may be appropriately adjusted according to specifications.

이상에서 설명하듯이, 본 발명에 따른 리튬/염화티오닐 전지는 애노드의 집전체 양면 중, 적어도 한 면에 리튬이 코팅되지 않은 부위가 존재한다. 이로인해, 리튬층이 형성되지 않은 부위에 해당하는 만큼 더 많은 전해액을 케이스에 주입할 수 있으므로, 애노드의 용량 비율에 비하여 충분히 많은 양의 전해액을 케이스에 주입할 수 있다. 따라서, 리튬이 소진되더라도, 항상 전해액은 잔존하므로, 방전시 생성되는 부산물인 황은 전해액에 녹아 존재하게 되고, 이상에 의해 열이 발생하더라도 잔존하는 전해액을 통하여 신속히 방열되므로, 안전사고를 완전히 예방할 수 있다.As described above, in the lithium / thionyl chloride battery according to the present invention, at least one side of the current collector of the anode has a portion not coated with lithium. Because of this, as much electrolyte solution can be injected into the case as it corresponds to the site where the lithium layer is not formed, a sufficiently large amount of electrolyte solution can be injected into the case compared to the capacity ratio of the anode. Therefore, even when lithium is exhausted, the electrolyte always remains, and sulfur, a by-product generated during discharge, is dissolved in the electrolyte, and heat is rapidly dissipated through the remaining electrolyte even when heat is generated. Thus, safety accidents can be completely prevented. .

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
