Description
본 고안은 부직포 투과막을 갖는 차량용 납축전지에 관한 것이다. 더욱 상세하게는, 차량용 납축전지의 상부에 액체의 투과는 억제하면서 기체의 투과는 자유롭게 유지할 수 있는 부직포 투과막을 설치한 차량용 납축전지에 관한 것이다.The present invention relates to a lead acid battery for a vehicle having a nonwoven permeable membrane. More specifically, the present invention relates to a vehicle lead acid battery provided with a nonwoven fabric permeable membrane that can freely maintain gas permeation while suppressing liquid permeation thereon.
첨부 도면 중 도 1은 종래의 일반적인 납축전지(10)의 일부분을 절개하여 나타낸 사시도이고, 도 2는 도 1의 납축전지(10)에서 사용 상태를 보여주기 위한 하나의 셀의 측 단면도로서, 부호 11은 용기, 부호 12는 (+) 단자, 부호 13는 (-) 단자, 부호 14는 PbO2판, 부호 15는 Pb 판, 부호 16은 전해액, 부호 17은 전극 연결자, 부호 18은 셀 분리판, 부호 19는 격리판이다.1 is a perspective view showing a portion of a conventional lead acid battery 10 according to the related art. FIG. 2 is a side cross-sectional view of one cell for showing a state of use in the lead acid battery 10 of FIG. 1. 11 is vessel, 12 is (+) terminal, 13 is (-) terminal, 14 is PbO 2 plate, 15 is Pb plate, 16 is electrolyte, 17 is electrode connector, 18 is cell separator , Code 19 is the separator.
일반적으로 종래의 차량용 납축전지(10)의 전해액(16)은 사용이 편리하고, 성능이 우수한 반면에 제조단가는 저렴한 황산과 물의 혼합물을 사용한다. 이와 같이 제조된 황산과 물의 혼합물은 상온 상압 하에서 액상이기 때문에 자동차의 움직임에 따라 유동하는 특징을 갖는다.In general, the electrolyte 16 of the conventional lead acid battery 10 for a vehicle is convenient to use and has excellent performance, while the manufacturing cost uses a mixture of sulfuric acid and water inexpensive. Since the mixture of sulfuric acid and water prepared as described above is liquid at room temperature and normal pressure, the mixture of sulfuric acid and water flows as the vehicle moves.
상기한 바와 같은 특징은 도 1에 예시한 바와 같이, 일반적인 차량의 움직임에서는 특별한 문제점이 발생하지 않지만, 차량이 균형된 형태로 배치되어 있지 못한 상황에서는 도 2에 예시한 바와 같이 차량에 고정되어 있는 납축전지(10) 용기(특히 전극)는 차량의 상태와 동일하게 균형 잡지 못한 형태의 기울기를 가지게 되고 액상의 전해액(16)도 중력의 방향과 수직을 유지하려는 성질을 보이게 된다.As illustrated in FIG. 1, the above-described feature does not cause any particular problem in general vehicle movement, but is fixed to the vehicle as illustrated in FIG. 2 when the vehicle is not arranged in a balanced form. The lead-acid battery 10 container (especially the electrode) has an unbalanced slope in the same manner as the state of the vehicle, and the liquid electrolyte 16 also exhibits a property of maintaining the direction perpendicular to the direction of gravity.
이러한 배치는 전해액(16)에 함침되어 있어야만 하는 전극판(14,15)의 일부분이 경사진 전해액의 수면(16')에 의해 대기중으로 노출되게 되고, 그로 인해 전극판의 손상 및 순간적인 과열에 의한 화재의 위험을 유발할 수 있게 된다.This arrangement results in a portion of the electrode plates 14, 15 that must be impregnated with the electrolyte 16 being exposed to the atmosphere by the water surface 16 ′ of the inclined electrolyte, resulting in damage to the electrode plate and instantaneous overheating. It may cause a risk of fire.
이에 본 고안은 종래의 차량용 납축전지가 갖고 있는 차량 불균형 상태에서 납축전지를 사용했을 때 발생할 수 있는 전극판의 대기중으로의 노출에 따른 전극판의 손상 및 화재의 위험성을 방지하기 위하여 전해액의 상부에 부직포 투과막을 설치한 납축전지를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention is designed to prevent damage to the electrode plate and risk of fire caused by exposure of the electrode plate to the atmosphere, which may occur when the lead acid battery is used in a vehicle imbalance state of the conventional vehicle lead acid battery. It is an object to provide a lead acid battery provided with a nonwoven fabric permeable membrane.

본 고안은 납축전지에 있어서, 전해액의 상부에 그 수면을 따라 액체의 투과는 억제하면서 기체의 투과는 자유롭게 유지할 수 있는 부직포로 된 투과막을 밀폐 구조로 장착한 것을 특징으로 한다.The present invention is characterized in that in a lead-acid battery, a permeable membrane made of a nonwoven fabric capable of freely maintaining gas permeation while suppressing permeation of liquids along the water surface thereof is provided in a sealed structure.
이하 본 고안을 첨부 도면에 의거하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도 3은 본 고안에 따른 부직포로 된 투과막이 장착된 납축전지의 일부를 절개하여 나타낸 사시도 이고, 도 4는 도 3의 납축전지의 사용 상태를 보여주기 위한 하나의 셀의 측 단면도를 나타낸 것이며, 도 1 및 2와 동일 부품에 대해서는 동일 부호를 사용하기로 한다.3 is a perspective view showing a portion of a lead acid battery equipped with a permeable membrane made of a nonwoven fabric according to the present invention, FIG. 4 is a side cross-sectional view of one cell to show a state of use of the lead acid battery of FIG. The same reference numerals will be used for the same parts as those of FIGS. 1 and 2.
도 3에서 본 고안의 투과막(20)은 2V 전압을 나타내는 셀의 전해액(16) 바로 위에 위치하면서 전해액(16)이 외부로 유출되는 것을 억제할 수 있게끔 각각의 셀과 외부를 밀폐하도록 설치하는 것이 바람직하다. 또한, 기체가 셀의 외부로 유출되지 못함으로써 발생할 수 있는 폭발 현상을 방지하기 위하여 기체의 투과는 자유롭게 유지하는 특성을 갖도록 하는 것이 바람직하다.In FIG. 3, the permeable membrane 20 of the present invention is disposed directly above the electrolyte solution 16 of a cell exhibiting a 2V voltage, and installed to seal each cell and the outside so as to suppress leakage of the electrolyte solution 16 to the outside. It is preferable. In addition, in order to prevent an explosion phenomenon that may occur due to the gas not leaking to the outside of the cell, it is desirable to have the property of freely maintaining the permeation of the gas.
본 고안에 따른 부직포 투과막은 납축전지(10)의 용기 뚜껑(21)에 일체시켜서 제조한 것을 사용할 수도 있다.The nonwoven fabric permeable membrane according to the present invention may be prepared by integrating the container lid 21 of the lead acid battery 10.
본 고안에 따른 부직포 투과막(20)은 도 4에 예시한 바와 같이 차량이 수평을 유지하고 있지 못한 상태에서 전해액(16)이 중력 방향에 수직으로 형성되기 위하여 움직이는 것을 방지할 수 있고, 이 결과 전극(14,15)이 전해액 외부로 노출되는 것도 방지할 수 있다. 여기서, 부호 16"는 경사진 전해액의 수면을 나타낸다.As illustrated in FIG. 4, the nonwoven permeable membrane 20 according to the present invention can prevent the electrolyte 16 from moving to form perpendicular to the direction of gravity in a state where the vehicle is not kept horizontal. Exposing the electrodes 14 and 15 to the outside of the electrolyte can also be prevented. Here, reference numeral 16 ″ denotes the water surface of the inclined electrolyte solution.
본 고안에 의한 납축전지는 액상 전해액이 갖고 있는 제조 용이성, 저비용 및 우수한 성능을 유지하면서 단점으로 알려진 전해액 누액에 의한 기기 손상을 억제할 수 있는 장점이 있다.The lead acid battery according to the present invention has an advantage of preventing device damage due to electrolyte leakage known as a disadvantage, while maintaining ease of manufacture, low cost, and excellent performance of the liquid electrolyte.
특히, 차량용 납축전지가 갖고 있는 차량의 불균형시 발생하는 전극 노출에 의한 납축전지의 성능저하 및 화재의 위험을 예방할 수 있다는 장점이 있다.In particular, there is an advantage that it is possible to prevent the performance degradation of the lead acid battery and the risk of fire due to the exposure of electrodes generated when the vehicle lead acid battery has an imbalance.
