본 발명은 활물질(Active Material)의 탈락을 방지하면서도 전해액의 유동을 용이하게 하여 충방전시의 화학반응을 원활하게 할 수 있는 납축전지를 제공하기 위한 것으로 특히 골프카, 보트, 지게차 등의 동력원으로 쓰이는 Deep cycle용 납축전지의 개량에 관한 것이다.The present invention is to provide a lead acid battery that can facilitate the flow of the electrolyte while preventing the drop of the active material (active material) to facilitate the chemical reaction during charging and discharging, in particular as a power source such as golf cars, boats, forklifts It is related to the improvement of lead acid battery for deep cycle.

납축전지는 보통 폴리에치렌계의 고분자물질로 된 격리판(Separator)으로 극판(Grid)과 극판을 격리시키되, 내면에 돌조(Rib)가 형성된 폴리에치렌 포대(Envelope)로 격리판을 형성시키고, 포대로된 격리판을 이웃하고 있는 양극판이나 음극판 중 하나의 극판에 씌워 형성시켜 왔다.The lead acid battery is usually a separator made of a polymer of polyethylene. The separator is separated from the grid, but the separator is formed of a polyetchene envelope having a rib formed therein. In other words, the enclosed separator is formed by covering one of the neighboring anode plates or cathode plates.

이와같은 납축전지에 있어서는 전해액의 유동이 비교적 용이하여 전지의 선능이 우수하나 극판에 부착한 활물질을 눌러주지 못하고, 특히 골프카, 보트, 지게차 등의 동력원으로 사용되는 축전지의 경우에 있어서와 같이 충방전을 수시로 하는 Deep cycle용 축전지에 있어서는 부식과 덴드라이트(Dendrite)의 형성이 빨라 활물질이 조기에 탈락하는 결점이 있었다.In such lead-acid batteries, the electrolyte flows relatively easily, so the battery is excellent in performance, but the active material attached to the electrode plate cannot be pressed, and in particular, as in the case of a storage battery used as a power source for golf cars, boats and forklifts. In deep cycle storage batteries that discharge frequently, corrosion and dendrite formation quickly resulted in the defect of the active material falling off prematurely.

그리하여 위와같은 Deep cycle용 축전지의 경우에 있어서는 극판과 극판 사이에 그래스 매트(Glass mat)를 설치하여 극판을 압착하므로서 활물질의 탈락을 감소시켜 왔다.Thus, in the case of the deep cycle storage battery as described above, a glass mat is installed between the pole plate and the pole plate to compress the pole plate, thereby reducing the dropping of the active material.

그런데 이와 같은 납축전지의 경우에 있어서는 상술한 바와같은 폴리에치렌계의 고분자물질로된 격리판을 사용한 축전지에 비하여, 축전지의 두께, 전해액의 함침량 및 유동 가능한 황산량 등이 열세여서 전지의 용량이 적어지고, 충방전 성능이 떨어지는 결점이 있다.However, in the case of such a lead acid battery, the capacity of the battery is lower because the thickness of the battery, the amount of electrolyte impregnation, and the amount of sulfuric acid that can flow are inferior to those of the battery cell using the separator made of the above-described polyethylene-based polymer material. There is a disadvantage that there is less and the charge / discharge performance is lowered.

그리하여 본 발명은 상술한 바와같은 폴리에치렌계의 고분자물질로 된 격리판을 사용한 축전지가 가지는 전해액의 유동 등에 있어서의 장점을 유지하면서도 극판에 부착한 활물질의 탈락을 감소시킬 수 있는 축전지를 제공할 수 있도록 극판의 표면에 얇은 섬유망체를 씌우고 그 외측에 상술한 바와 같은 폴리에치렌계의 고분자물질로 형성되고 돌조를 가진 격리판을 설치한 축전지를 제공하기에 이르렀는 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Thus, the present invention can provide a storage battery that can reduce the dropping of the active material attached to the electrode plate while maintaining the advantages in the flow of the electrolyte solution and the like having a separator using a polyethylene-based polymer material as described above. To cover the surface of the pole plate with a thin fibrous mesh, and to the outside of the polyetherene-based high-molecular material as described above to provide a storage battery provided with a separator having a bar, attached to the present invention Referring to the drawings as follows.

표면에 활물질층(2)을 부착시킨 다수개의 극판(1)으로 구성된 축전지에 있어서, 활물질층(2)의 외면에 얇은 섬유망체(3)를 부착하고, 폴리에치렌계의 고분자물질로 형성되고 내면에 돌조(41)가 형성된 공지의 격리판(4)을 섬유망체(3)의 외면에 설치한다.In the storage battery consisting of a plurality of electrode plates (1) having the active material layer (2) attached to the surface, a thin fiber net (3) is attached to the outer surface of the active material layer (2), and formed of a polyethylene-based polymer material The well-known separator 4 in which the protrusion 41 was formed in the inner surface is attached to the outer surface of the fiber mesh 3.

섬유망체(3)는 황산에 반응하지 아니하는 모든 섬유소재가 널리 사용될 수 있으며, 그 두께는 가능한한 얇은 것이 바람직하며, 섬유망체(3)의 망목의 크기는 25~120메쉬(Mesh)인 것이 바람직하다.The fibrous mesh 3 may be widely used for all fibrous materials which do not react with sulfuric acid. The thickness of the fibrous mesh 3 is preferably as thin as possible, and the size of the mesh of the fibrous mesh 3 is 25 to 120 mesh. desirable.

이와같이 구성된 본 발명은 그래스 매트를 사용하지 아니하므로 극판과 극판 사이에 비교적 많은 공간을 확보할 수 있게 하여 이 공간부에 많은 량의 전해액을 충전시킬 수 있어 전지의 용량과 수명을 증대시킬수 있으며, 활물질층(2)의 외면에 섬유망체(3)를 설치하므로서 활물질층(2)의 탈락을 감소시킬 뿐 아니라 덴드라이트의 성장을 억제할 수 있으며, 격리판의 두께를 감소시킬 수 있어 축전지의 크기를 감소시킬 수 있는 효과가 있다.The present invention configured as described above does not use a grass mat, so that a relatively large space can be secured between the electrode plate and the electrode plate, so that a large amount of electrolyte can be filled in this space, thereby increasing the capacity and life of the battery, and the active material. By installing the fibrous mesh 3 on the outer surface of the layer 2, not only the dropout of the active material layer 2 can be reduced, but also the growth of dendrites can be suppressed, and the thickness of the separator can be reduced, thereby reducing the size of the battery. There is an effect that can be reduced.
