Abstract
니켈 수소전지는 캔의 내부에 세페레이터를 사이에 두고 양극판과 음극판이 원통상으로 감겨지는 구조를 갖는다.The nickel hydride battery has a structure in which a cathode plate and a cathode plate are wound in a cylindrical shape with a separator interposed therebetween.
이러한 캔의 내부에는 전해액이 넣어지게 되는데, 이 전해액은 세페레이터에 함습되는 상태로 존재하게 된다.An electrolyte is put inside the can, and the electrolyte is present in a state of being impregnated with the separator.
따라서 전해액의 존재량은 세페레이터의 함습양에 따라 결정되는 것이므로 이 세페레이터의 함습량을 증가시켜 전지의 특성을 향상시키고자 한다.Therefore, since the amount of electrolyte is determined by the moisture content of the separator, the moisture content of the separator is increased to improve the characteristics of the battery.
이러한 세페레이터는 그 두께를 종래의 세페레이터 두께보다 절반으로 하고 길이를 2배로 하여 절반을 접은 상태로 사용하는 것이다.Such a separator is used in a state in which the thickness of the separator is half the thickness of the conventional separator and the length is doubled and the half is folded.
Description
본 고안은 니켈 수소전지에 관한 것으로서, 보다 상세하게는 세페레이터의 두께를 얇게 하여 전해액의 함습량을 증가시킴으로서 전지의 특성을 향상시킬 수 있는 니켈 수소전지에 관한 것이다.The present invention relates to a nickel hydride battery, and more particularly, to a nickel hydride battery that can improve the characteristics of the battery by increasing the moisture content of the electrolyte by reducing the thickness of the separator.
잘 알려진 바와 같이 2차 전지 중에서 니켈 수소전지는, 양극으로 금속화합물을 사용하고, 음극으로 수소저장 합금을 사용하여, 충전시에 음극에서 발생된 수소를 수소 저장합금이 흡수하고, 방전시 필요한 수소를 전해액 내로 방출하므로서 충전과 방전을 반복할 수 있는 구조를 갖추고 있다.As is well known, nickel hydride batteries in secondary batteries use a metal compound as a positive electrode and a hydrogen storage alloy as a negative electrode. The hydrogen storage alloy absorbs the hydrogen generated at the negative electrode during charging, and the hydrogen required for discharge. It discharges into the electrolyte and has a structure capable of repeating the charging and discharging.
이러한 전지의 캔의 내부에 양극판과 음극판이 세페레이터를 사이에 두고 감겨진 상태로 존재하게 되고, 이러한 양극판과 음극판이 넣어진 캔에는 전해액이 넣어져 전지로서의 기능을 가능하게 하고 있다.The positive electrode plate and the negative electrode plate exist inside the can of the battery with the separator interposed therebetween, and the can into which the positive electrode plate and the negative electrode plate are placed contains an electrolyte solution to enable a function as a battery.
그러나 상기한 전지의 구조에서 세페레이터는 전해액을 함습하는 작용을 하게 되는데, 이 세페레이터의 두께가 0.15mm로 되어 있기 때문에 전해액을 함습하는데 오랜 시간이 소요되며, 또 충분한 함습을 하지 못하고 있다.However, in the structure of the battery described above, the separator acts to impregnate the electrolyte solution, and since the separator has a thickness of 0.15 mm, it takes a long time to impregnate the electrolyte solution and does not provide sufficient humidity.
따라서 전지의 수명이 짧아지는 한 요인이 되고 있으며, 전지의 용량이 작아지는 단점으로 지적되고 있다.Therefore, the battery life has become a factor of shortening, and the battery capacity is pointed out as a disadvantage.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 전해액의 함습량을 증가시켜 전지의 제반 특성을 향상시킬 수 있는 니켈 수소전지를 제공하는데 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 nickel-metal hydride battery that can improve the overall characteristics of the battery by increasing the moisture content of the electrolyte.
상기한 바와 같은 본 고안의 목적을 실현하기 위하여, 캔의 내부에 나선상으로 감겨지는 양극판과 음극판, 그리고 이들 양음극판 사이에 위치되는 세페레이터를 포함하는 니켈 수소전지에 있어서, 상기한 세페레이터는 2장의 겹침구조로 이루어짐을 특징으로 하는 니켈 수소전지를 제공한다.In order to achieve the object of the present invention as described above, in a nickel-metal hydride battery comprising a positive electrode plate and a negative electrode plate spirally wound inside the can and a separator positioned between these positive electrode plates, the separator is 2 Provided is a nickel-metal hydride battery, characterized in that the stack structure of the field.
상기한 세페레이터의 1면 두께는 0.75mm인 것을 특징으로 하는 니켈 수소전지를 제공한다.The thickness of one surface of the separator is 0.75mm to provide a nickel hydride battery.
도 1은 본 고안에 의한 니켈 수소전지의 부분 측단면도.1 is a partial side cross-sectional view of a nickel hydride battery according to the present invention.
도 2는 본 고안에 관련하는 세페레이터의 부분 절개 사시도.2 is a partial cutaway perspective view of a separator according to the present invention.
이하 본 고안의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.
도 1은 본 고안에 의한 전지의 부분 측단면도로서, 캔(2)의 내부에는 양극판(4)과 음극판(6)이 나선상으로 감겨져 수용되고 있으며, 이들 양극판과 음극판 사이에는 세페레이터(8)가 동일한 형상으로 감겨진 구조를 취하고 있다.1 is a partial side cross-sectional view of a battery according to the present invention, in which a positive electrode plate 4 and a negative electrode plate 6 are wound in a spiral shape inside a can 2, and a separator 8 is disposed between the positive electrode plate and the negative electrode plate. The structure wound in the same shape is taken.
그리고 이 캔(2)의 상부에는 개스켓(10)을 사이에 두고 캡(12)이 설치되고 있다.And the cap 12 is provided in the upper part of this can 2 with the gasket 10 interposed.
상기한 세페레이터(8)는 도면에서 일측면이 2장의 판체로 도시되고 있는데, 그것은 도 2에 도시하고 있는 바와 같이 얇은 판체가 접혀진 구조로 이루어지고 있기 때문이다.The separator 8 is shown in the drawing as two plates on one side, because the thin plate is folded as shown in FIG.
이것은 세페레이터(8)의 일측면 두께가 0.75mm로 하여 겹침을 하였을 때 종래와 같이 0.15mm가 되도록 한 것이다.This is such that when the thickness of one side of the separator 8 is 0.75 mm, the thickness is 0.15 mm as in the prior art.
이러한 세페레이터는 두께가 종래보다 얇기 때문에 캔 내부에 넣어지는 전해액을 단시간내에 많이 함습할 수 있다.Since the separator is thinner than the conventional one, the separator can be impregnated with a large amount of the electrolyte contained in the can within a short time.
이상 설명한 바와 같이 본 고안에 의한 니켈 수소전지는, 세페레이터의 두께를 얇게 하므로서 전해액의 함습량을 증가시킬 수 있어 전지의 충방전 용량을 크게 할 수 있으며, 또 전지의 수명을 연장시킬 수 있는 효과가 있다.As described above, the nickel hydride battery according to the present invention can increase the moisture content of the electrolyte by reducing the thickness of the separator, thereby increasing the charge / discharge capacity of the battery, and extend the life of the battery. There is.
