Abstract
Description
본 발명은 산업용 튜블라 납축전지에 관한 것이다. 더욱 상세하게는 중력 주조법으로 제작이 가능하도록 스파인의 구조를 변경한 산업용 튜블라 납축전지에 관한 것이다.The present invention relates to an industrial tubular lead acid battery. More particularly, the present invention relates to an industrial tubular lead acid battery in which the structure of a spine is changed to be manufactured by a gravity casting method.
산업용 납축전지의 수요는 통신산업의 발달에 따라 증가하고 있다. 현재 고용량 산업용 납축전지는 수명 특성이 가장 중요하며, 15년 이상 수명을 보장하여야 한다. 장수명을 위하여 튜블라형 극판을 사용하고, 자동차용 납축전지의 기판과는 달리 도 1과 같은 스파인(spine)을 사용하고 있다.The demand for industrial lead acid batteries is increasing with the development of the telecommunications industry. At present, the high capacity industrial lead acid battery is the most important life characteristics, and should guarantee the life of more than 15 years. A tubular pole plate is used for long life, and unlike a substrate of an automotive lead acid battery, a spine as shown in FIG. 1 is used.
그러나, 현재 사용 중인 스파인은 살의 길이가 길기 때문에 종래 자동차용 기판의 제조방법인 중력 주조법을 사용하지 못하고, 고가의 압력 주조법을 사용하여야 하는 단점이 있다. 압력 주조법을 사용하기 때문에 산업용 전지의 기판 주조기와 자동차용 전지의 기판 주조기를 함께 사용하지 못하고 있다.However, the spine currently in use does not use the gravity casting method, which is a conventional method for manufacturing a substrate for automobiles, because the length of the flesh is long, there is a disadvantage that an expensive pressure casting method should be used. Due to the use of the pressure casting method, the substrate casting machine for industrial batteries and the substrate casting machine for automobile batteries cannot be used together.
중력 주조가 가능하기 위해서는 스파인의 가로와 세로의 구조를 서로 바꾸어 스파인의 살의 길이를 짧게 하면 가능하지만 젤 전해질의 충진, 단자 설계 등의 문제로 전지에 채용되지 못하고 있다.In order to enable gravity casting, it is possible to shorten the length of the spine by changing the structure of the spine horizontally and vertically, but it is not adopted in the battery due to the problem of filling of the gel electrolyte and terminal design.
현재 산업용 튜블라 납축전지의 제공공정은 다음과 같다. 압력 주조법으로 양극용 스파인을 제조하고, 곤틀렛으로 불리는 튜브를 스파인에 끼운 후, 거꾸로 하여 활물질을 밑으로부터 채워 넣는다. 음극은 격자형 기판에 활물질을 도포하여 제작한다. 제작한 극판을 양극과 격리판 음극을 차례로 쌓아, 극판군을 형성하고, 젤 전해질을 위로부터 충진시켜 전지를 완성한다. 그러나, 젤 전해질은 완전한 고체 상태가 아니므로, 시간에 따라 전해질 상부와 하부와 농도 차이가 발생할 가능성을 가지고 있다.At present, the process of providing industrial tubular lead acid battery is as follows. The positive electrode spine is produced by a pressure casting method, a tube called a goletlet is inserted into the spine, and then the upside down is filled with the active material from below. The negative electrode is prepared by coating an active material on a lattice substrate. The produced electrode plate is stacked in order of the positive electrode and the separator negative electrode in order to form a group of electrode plates, and the gel electrolyte is filled from above to complete the battery. However, since gel electrolytes are not completely solid, there is a possibility of concentration differences between the upper and lower electrolytes over time.
이와 같은 문제점을 해결하기 위해 본 발명은 기존의 스파인의 가로, 세로의 형태를 서로 바꾸어 중력 주조가 가능하도록 하는데 그 목적이 있다.In order to solve such a problem, the present invention has an object to enable gravity casting by changing the shape of the existing spine horizontally and vertically.

도 6은 본 발명에 따른 완성된 납축전지를 나타낸 도면이다.6 is a view showing a completed lead acid battery according to the present invention.
본 발명은 산업용 튜블라 납축전지에 있어서, 양극판용 스파인은 다수의 살(1)들이 수평하게 배열되고, 살의 방향이 전지 길이 방향에 수직인 것을 특징으로 하는 산업용 튜블라 납축전지이다.In the present invention, the industrial tubular lead acid battery, the positive electrode plate spine is an industrial tubular lead acid battery, characterized in that a plurality of flesh (1) is arranged horizontally, the direction of the flesh is perpendicular to the battery longitudinal direction.
본 발명의 양극용 스파인을 이용한 납축전지 제조방법은 다음과 같다.The lead acid battery manufacturing method using the spine for the positive electrode of the present invention is as follows.
본 발명의 따른 스파인은 도 2와 같이 스파인의 살(1)의 수를 늘리고, 살의 방향을 전조 길이 방향에 수직으로 함으로써, 스파인 길이를 종래 최대 600㎜에서 200㎜ 내외로 짧게 하여, 중력 주조법을 이용하여 제작하고, 제작한 스파인에 곤틀렛을 끼우고, 종래의 방법과 동일한 방법으로 활물질을 충진한다. 이때 스파인 길이가 짧기 때문에 충진 시간을 단축할 수 있다.In the spine according to the present invention, as shown in Fig. 2, by increasing the number of the spine flesh (1) and making the direction of the flesh perpendicular to the roll length direction, the spine length is shortened from about 600 mm to 200 mm in the past, It is made by using the same material, and the ganlets are put in the produced spine, and the active material is filled in the same manner as in the conventional method. At this time, the filling time can be shortened because the spine length is short.
제작한 양극판을 종래의 방법으로 제작한 음극판과 극판군을 형성하고, 도 3과 같이 양극 단자가 음극 단자와 대칭이 되도록 스트랩(strap)을 형성한다. 음극의 스트랩은 도 3의 (a)와 같이 중앙에 형성하고, 양극 스트랩은 도 3의 (b)와 같이 가장자리에서 중앙으로 형성한다.The negative electrode plate produced by the conventional method is formed with a negative electrode plate and a pole plate group, and a strap is formed such that the positive electrode terminal is symmetrical with the negative electrode terminal as shown in FIG. 3. The negative electrode strap is formed at the center as shown in FIG. 3 (a), and the positive electrode strap is formed at the edge at the center as shown in FIG.
형성한 극판군은 1면이 개봉된 전지 케이스에 넣고, 겔 전해질을 충진하거나 또는 도 4의 (1)과 같은 2면이 개방된 전지 케이스에 도 5의 (a)과 같은 방법으로 넣고, 도 4의 (2)의 뚜껑으로 상부를 막아서, 도면 5의 (b)와 같이 측면이 개봉된 전지 케이스에 겔 전해질을 종래의 방법으로 충진한다. 후자의 경우에는 겔 상태의 전해질이 이동하여야 하는 거리를 짧게하여 보다 균일하고 빠르게 전해질을 충진할 수 있다.The formed electrode plate group is placed in a battery case in which one side is opened, and filled with a gel electrolyte, or put in a battery case in which two sides are opened as shown in (1) of FIG. 4 in the same manner as in FIG. The upper part is blocked with the lid of 4 (2), and the gel electrolyte is filled into the battery case in which the side surface is opened as shown in FIG. In the latter case, it is possible to fill the electrolyte more uniformly and quickly by shortening the distance that the gel electrolyte should move.
충진이 완료된 전지를 도 4의 (3)의 전조 측면으로 밀봉함으로써 전지가 완성된다.The battery is completed by sealing the completed battery with the rolling side of Fig. 4 (3).
완성된 전지는 도 6과 같이, 세워서 사용하거나, 뉘어서 사용할 수 있다.The finished battery can be used upright or as shown in FIG. 6.
스파인의 형태를 도 2와 같이 변경함으로써 다음과 같은 장점을 얻을 수 있다.By changing the shape of the spine as shown in Figure 2 it can be obtained the following advantages.
첫째, 중력 주조가 가능하여, 기존의 자동차용 기판 주조기와 함께 사용할 수 있고, 이에 따라, 기계의 효율을 증대할 수 있다.First, the gravity casting is possible, can be used with the existing automotive substrate casting machine, thereby increasing the efficiency of the machine.
둘째, 스파인의 살의 길이를 줄이므로, 활물질 충진 시간을 단축하고 보다 균일하게 충진할 수 있다.Second, since the length of the spine flesh is reduced, the filling time of the active material can be shortened and more evenly filled.
셋째, 전지 케이스 옆면에서 전해질을 주입하므로, 보다 신속하고 균일하게 전해질을 충진할 수 있다.Third, since the electrolyte is injected from the side of the battery case, the electrolyte can be filled more quickly and uniformly.
네째, 튜브의 결이 전지와 수직으로 놓이므로, 젤 전해질을 흐름을 억제하여, 보관 도중 농도 차이가 생기는 것을 막아준다.Fourth, because the tube is placed perpendicular to the cell, it inhibits the flow of the gel electrolyte and prevents concentration differences during storage.
전지 케이스를 도 4와 같이 세 부분으로 나누어 조립함으로써 도 2의 스파인을 사용 가능하게 하고, 측면에서의 젤 전해질을 주입함으로써, 젤 전해질 주입 거리를 단축하여 보다 균일한 전해질을 얻을 수 있다.By assembling the battery case into three parts as shown in FIG. 4, the spine of FIG. 2 can be used, and by injecting the gel electrolyte from the side surface, the gel electrolyte injection distance can be shortened to obtain a more uniform electrolyte.
