본 고안은 무지부를 형성한 극판에 관한 것으로서, 더욱 상세하게는 극판의 네모서리에 무지부를 형성하여 단락을 방지한 무지부를 형성한 극판에 관한 것이다.The present invention relates to a pole plate having a plain portion, and more particularly, to a pole plate having a plain portion formed by forming a plain portion at a corner of the pole plate to prevent a short circuit.
일반적으로 2차전지는 재충전이 가능한 전지로서, 니켈-카드뮴 전지와 니켈-수소전지 등이 있다.In general, secondary batteries are rechargeable batteries, and include nickel-cadmium batteries and nickel-hydrogen batteries.
상기한 니켈-수소전지는 띠형상의 양극판과 음극판의 사이에 단락방지용 절연판을 삽입한 다음 여러겹으로 말아서 형성한 전극부를 캔 안에 설치하고, 상기한 캔 안에 수산화칼륨(KOH), 수산화나트륨 (NaOH), 수산화니켈(NiOH) 등의 전해액을 주입하여 제조한다.In the nickel-hydrogen battery, a short-circuit-proof insulating plate is inserted between a strip-shaped positive electrode plate and a negative electrode plate, and then an electrode part formed by rolling several layers is installed in a can, and potassium hydroxide (KOH) and sodium hydroxide (NaOH) are contained in the can. ), And prepared by injecting an electrolyte such as nickel hydroxide (NiOH).
상기한 음극판은 집전체에 활물질(예를 들면 Ni(OH)2 등)을 충전하고 압연하는 것으로 형성된다.The negative electrode plate is formed by charging and rolling an active material (for example, Ni (OH) 2, etc.) to a current collector.
제3도에 나타낸 바와 같이, 종래의 음극판(2)은 활물질을 충전하기 위한 다수의 충전구멍(6)이 형성된 천공부(4)가 전면적에 걸쳐 형성된다.As shown in FIG. 3, the conventional negative electrode plate 2 is formed with a perforated portion 4 formed with a plurality of filling holes 6 for filling the active material over the entire area.
또 제4도에 나타낸 바와 같이, 종래의 음극판(8)의 다른 예는 활물질을 충전하기 위한 다수의 충전구멍(6)이 형성된 천공부(4)와, 길이방향의 양모서리 끝부분이 직선형상이고 소정의 폭으로 활물질을 초음파 또는 물로 세정·제거하여 형성된 무지부(9)로 이루어진다.In addition, as shown in FIG. 4, another example of the conventional negative electrode plate 8 is a perforated portion 4 formed with a plurality of filling holes 6 for filling the active material, and both ends of the longitudinal edges are straight. It consists of the plain part 9 formed by wash | cleaning and removing an active material with ultrasonic wave or water in a predetermined width | variety.
[고안이 이루고자 하는 기술적 과제][Technical Challenges to be Done]
상기와 같이 구성된 종래의 음극판에 있어서는 폭방향의 양모서리 또는 네모서리 모두에 반원형상의 흠이 형성되어 있기 때문에, 절연판을 사이에 두고 양극판과 함께 감아서 전극부를 형성할 때에 날카로운 상기한 반원형상 홈의 끝부분에 의하여 상기한 절연판이 파손되어 양극판과 음극판이 단락된다는 문제가 있다.In the conventional negative electrode plate configured as described above, since semicircular flaws are formed in both the edges or the four corners of the width direction, the above-described semicircular grooves sharp when the electrode portion is formed by winding the positive electrode plate with the insulating plate therebetween. There is a problem in that the insulating plate is damaged by the end and the positive electrode plate and the negative electrode plate are short-circuited.
또 모서리 끝부분에 충전된 활물질이 이탈되기 쉽기 때문에 활물질에 의하여 전해액이 오염되고 용량이 감소된다는 문제가 있다.In addition, since the active material filled at the edge is easily separated, there is a problem that the electrolyte is contaminated by the active material and the capacity is reduced.
[과제를 해결하기 위한 수단][Means for solving the problem]
상기와 같은 문제를 해결하기 위하여 본 고안이 강구한 수단은 활물질을 충전하기 위한 다수의 충전구멍이 형성된 천공부와, 상기한 천공부의 네모서리 바깥쪽에 소정의 폭으로 활물질을 제거하여 형성되는 무지부를 포함하는 무지부를 형성한 극판을 제공하는 것이다.Means devised by the present invention to solve the above problems is a plain formed by removing the active material with a predetermined width on the outer periphery of the four corners of the hole formed with a plurality of filling holes for filling the active material It is to provide a pole plate formed of a plain portion including a portion.
상기한 무지부의 바깥 부분은 직선형상으로 형성되고, 네귀퉁이는 원형모따기를 행하는 것이 바람직하다.It is preferable that the outer part of the said uncoated part is formed in linear form, and four corners perform circular chamfering.
상기와 같이 구성되는 본 고안 무지부를 형성한 극판의 제조는 먼저 극판의 소재에 일정한 간격으로 배열하여 다수의 충전구멍을 가공하고, 상기한 충전구멍이 가공된 극판의 소재에 활물질을 충전한다음. 네 모서리에서 소정의 폭으로 초음파 또는 물로 세정하여 활물질을 제거하여 무지부를 형성하여 이루어진다.The manufacturing of the pole plate formed with the non-woven portion of the present invention constituted as described above is first arranged at regular intervals on the material of the pole plate to process a plurality of filling holes, and the active material is filled in the material of the pole plate processed the filling hole. It is made by forming an uncoated portion by removing the active material by washing with ultrasonic waves or water in a predetermined width at four corners.
[실시예]EXAMPLE
다음으로 본 고안 무지부를 형성한 극판의 가장 바람직한 실시예를 도면을 참조하여 상세하게 설명한다.Next, the most preferable embodiment of the pole plate which formed the uninvented part of this invention is demonstrated in detail with reference to drawings.
먼저 제1도에 나타낸 바와 같이 본 고안 무지부를 형성한 극판의 일실시예는 활물질을 충전하기 위한 다수의 충전구멍(6)이 형성된 천공부(4)와, 상기한 천공부(4)의 네모서리 바깥쪽에 소정의 폭으로 활물질을 제거하여 형성되는 무지부(12)를 포함한다.First, as shown in FIG. 1, one embodiment of the electrode plate having the inventive non-woven portion includes a perforated portion 4 having a plurality of filling holes 6 for filling an active material, and four of the perforated portions 4 described above. It includes a non-coated portion 12 formed by removing the active material in a predetermined width outside the corner.
상기한 무지부(12)의 바깥부분은 직선현상으로 형성되고, 네귀퉁이는 모따기 (특히 원형모따기)를 행하는 것이 바람직하다.The outer portion of the plain portion 12 is formed in a straight line phenomenon, and four corners are preferably chamfered (particularly round chamfered).
상기와 같이 구성되는 본 고안 무지부를 형성한 극판의 제조방법을 설명한다.The manufacturing method of the pole plate which formed the uninvented part of this invention comprised as mentioned above is demonstrated.
