Description

2차 전지의 극판 제조방법Manufacturing method of pole plate of secondary battery

제1도는 본 발명에 따른 2차 전지의 극판 제조방법을 설명하기 위해 도시한 개략 사시도이고,1 is a schematic perspective view for explaining a method of manufacturing a pole plate of a secondary battery according to the present invention,

제2도 및 제3도는 종래 기술에 의한 2차 전지의 극판 제조방법을 설명하기 위해 도시한 도면이다.2 and 3 are views for explaining a method for manufacturing a pole plate of a secondary battery according to the prior art.

[산업상의 이용분야][Industrial use]

본 발명은 2차 전지의 극판 제조방법에 관한 것으로서, 보다 상세하게는 양,음극의 극판 제조시, 필수적으로 행하게 되는 결착제의 코팅을 효과적으로 이룰 수 있는 2차 전지의 극판 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a cathode plate of a secondary battery, and more particularly, to a method for manufacturing a cathode plate of a secondary battery capable of effectively forming a coating of a binder, which is essentially performed during production of a cathode plate of a cathode and a cathode.

[종래의 기술][Prior art]

잘 알려진 바와 같이, 2차 전지는 사용후 재사용이 가능한 전지로서, 이에는 니켈-카드뮴전지, 니켈-수소전지, 축전지 등이 포함되어 있다.As is well known, secondary batteries are batteries that can be reused after use, including nickel-cadmium batteries, nickel-hydrogen batteries, storage batteries, and the like.

이러한 2차 전지에 있어 니켈-수소전지는, 타 전지에 비해 무해한 특성을 지니고 있어 근래에 들어 그 사용이 급증되고 있는 실정이다.In such secondary batteries, nickel-hydrogen batteries have harmless properties compared to other batteries, and their use is increasing rapidly in recent years.

상기 니켈-수소전지는, 통상 양극으로 금속 산화물을 사용하고 음극으로는 수소 저장합금을 사용하여, 충전시 전해액 속의 물이 분해되어 생긴 수소를 수소 저장합금이 흡수하고, 방전시에는 필요한 수소를 전해액 내로 방출함으로써 충전과 방전을 반복하여 사용되게 된다.In the nickel-hydrogen battery, a metal oxide is generally used as a positive electrode and a hydrogen storage alloy is used as a negative electrode. The hydrogen storage alloy absorbs hydrogen generated by decomposition of water in the electrolyte during charging, and the required hydrogen is discharged when the electrolyte is discharged. By discharging into the battery, charging and discharging are repeated.

한편, 상기와 같은 니켈-수소전지는, 그 제조시에 양,음극판 제조공정에 있어, 양극판의 경우는 활물질이 극판으로부터 탈락됨을 방지하고, 음극판에 있어서는 극판 표면의 소수성(疏水性)을 증대시키기 위하여 결착제를 각 극판에 코팅하는 작업을 하게 된다.On the other hand, the nickel-hydrogen battery as described above, in the positive and negative electrode plate manufacturing process at the time of its manufacture, prevents the active material from falling off from the electrode plate in the case of the positive electrode plate, and increases the hydrophobicity of the surface of the electrode plate in the negative electrode plate. In order to do this, a binder is coated on each electrode plate.

종래에 행하고 있던 결착제의 코팅방법은, 크게 ① 침적법과 ② 스프레이 분사법으로 구분되고 있는데, 주로 침적법은 양극판의 제조시, 또한 스프레이 분사법은 음극판의 제조시 사용된다.Conventionally, the coating method of the binder is largely divided into (1) the deposition method and (2) the spray injection method. The deposition method is mainly used for the production of the positive electrode plate, and the spray injection method is used for the production of the negative electrode plate.

상기 침적법과 스프레이 분사법을 통해 결착제를 각 극판에 코팅하는 방법을 도면과 함께 개략적으로 알아보면 다음과 같다.The method of coating the binder on each electrode plate by the deposition method and the spray injection method will be described with reference to the drawings as follows.

제2도는 양극판의 제조시, 이 양극 극판에 결착제를 코팅하는 방법 즉, 침적법에 대한 참고 도면으로서, 상기 양극 극판(1)의 결착제를 코팅은 도면에서와 같이 상기 양극 극판(1)을 회전 롤러(3,5,7)를 이용하여 결착제 수용액이 담겨져 있는 침적조(9) 내를 통과시키면서 이루게 된다.FIG. 2 is a reference diagram for a method of coating a binder on the positive electrode plate, that is, a deposition method, during the manufacture of the positive electrode plate, and coating the binder of the positive electrode plate 1 as shown in the drawing. This is achieved while passing through the inside of the deposition tank 9 in which the binder aqueous solution is contained using the rotary rollers 3, 5 and 7.

또한, 상기한 침적법과는 달리, 음극 극판에 결착제를 코팅하는 방법인 스프레이 분사법은, 제3도에 도시된 것처럼, 음극 극판(11)이 결착제 코팅 공정으로 이송되어 오면, 이 음극 극판(11)의 상방으로부터 결착제 용액을 분사노즐(13)로 분사하여 상기 음극 극판(11)에 결착제를 코팅시키게 된다.In addition, unlike the deposition method described above, the spray spraying method, which is a method of coating a binder on a negative electrode plate, has a negative electrode plate when the negative electrode plate 11 is transferred to a binder coating process as shown in FIG. The binder solution is sprayed onto the injection nozzle 13 from above (11) to coat the binder on the negative electrode plate (11).

[발명이 해결하려고 하는 문제점][Problem trying to solve the invention]

그런데, 상기한 결착제 코팅방법이 포함된 종래의 2차 전지 극판 제조방법은, 각기 다음과 같은 문제점을 발생하고 있어 그 작업을 효율성을 떨어뜨리고 있는 실정이다.By the way, the conventional manufacturing method of the secondary battery pole plate containing the binder coating method, each of the following problems occurs, the situation is that the operation is reduced efficiency.

먼저, 양극 극판의 결착제 코팅시에는,First, in the binder coating of the positive electrode plate,

① 활물질을 그 표면에 도포한 양극 극판이 침적조 내를 통과시에 활물질이 탈락됨에 따라 양극의 활물질이 저하로 결국, 전지의 용량의 감소시키게 된다.(1) As the active material is dropped when the positive electrode plate coated with the active material on its surface passes through the deposition tank, the active material of the positive electrode is lowered, thereby reducing the capacity of the battery.

② 결착제의 코팅이 단순하게 침적내로 양극 극판이 침적되어 이루어지므로 결착제의 정확한 코팅량과 그 두께 조절에 어려움이 있다.② Because coating of binder is done by simply depositing positive electrode plate into deposit, it is difficult to control precise coating amount and thickness of binder.

③ 결착제의 코팅 작업시, 결착제 수용액의 잦은 교체로 이에 따른 재료 손실에 의해 작업비의 부담이 발생된다.③ During the coating work of the binder, the cost of work is incurred due to frequent material loss due to frequent replacement of the binder aqueous solution.

④ 양극 극판의 침적시, 이 양극 극판에 결착제 수용액이 침투되는 과정에서 조절된 결착제의 두께에 팽윤이 발생되므로 리프레싱(repressing)이 추가되어야 함에 따라 작업 공정수가 많게 된다.④ When the anode plate is deposited, swelling occurs in the adjusted thickness of the binder in the process of infiltrating the binder solution into the anode plate, so that the number of working steps increases due to the addition of repressing.

이와 달리, 음극 극판의 결착제 코팅시에는,In contrast, in the binder coating of the negative electrode plate,

① 결착제 용액의 분사 상태를 향상시키기 위해서 이 결착제 용액에 통상, 유기용매를 첨가하게 되는데, 그 조성 조절이 용이하지 않다.(1) In order to improve the spraying state of the binder solution, an organic solvent is usually added to the binder solution, but its composition is not easy to control.

② 결착제 용액의 분사 조건 및 코팅 두께의 영향이 분사 노즐의 형태에 따라 달라지게 되므로, 그 공정 제어에 어려움이 많다.② Since the influence of the spraying conditions and coating thickness of the binder solution depends on the type of spray nozzle, the process control is difficult.

[문제점을 해결하기 위한 수단][Means to solve the problem]

이에, 본 발명은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서, 결착제 코팅 공정수를 단축시켜 작업성 향상에 이점을 지니도록 할뿐만 아니라 결착제의 코팅을 양호하게 이루어 그 작업 효율을 향상시킬 수 있도록 하는 2차 전지의 극판 제조방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, shorten the number of binder coating process to have an advantage in improving workability as well as to improve the coating efficiency of the binder to improve its working efficiency It is an object of the present invention to provide a method for manufacturing a pole plate of a secondary battery.

이에 따라, 본 발명은 상기 목적을 실현하기 위하여, 2차 전지를 구성하는 양,음극판의 제조시, 상기 양,음극 극판에 결착제를 코팅하는 공정을 포함한 2차 전지의 극판 제조방법에 있어서, 상기 결착제의 코팅을, 마주 대하게 배치되어 결착제 수용액을 공급받아 회전 구동되는 롤러 사이로 코팅 대상의 극판을 통과시켜 이루는 2차 전지의 극판 제조방법을 제공한다.Accordingly, the present invention in the manufacturing method of the positive electrode plate of the secondary battery, including the step of coating a binder on the positive electrode, the negative electrode plate in the manufacture of the positive electrode, the negative electrode constituting the secondary battery, Provided is a method for manufacturing a pole plate of a secondary battery, the coating of the binder is disposed facing each other to pass through the electrode plate of the object to be coated between the rollers that are rotated by receiving the binder aqueous solution.

이때, 본 발명에서 상기 각 롤러의 외주면은 결착제 수용액의 함습이 가능한 재질로 형성됨을 특징으로 한다.At this time, the outer peripheral surface of each roller in the present invention is characterized in that it is formed of a material that can be moistened with the binder aqueous solution.

[실시예]EXAMPLE

이하, 첨부된 도면에 의거하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명에 따라 2차 전지용 양,음극 극판에 결착제를 코팅하는 방법을 설명하기 위해 도시한 개략 사시도로서, 상기 결착제의 코팅은 통상의 2차 전지용 극판 제조에 포함되어 있는 결착제 코팅을 나타낸다.1 is a schematic perspective view illustrating a method of coating a binder on a positive electrode plate and a negative electrode plate for a secondary battery according to the present invention, wherein the coating of the binder is a binder included in the manufacture of a normal electrode plate for secondary batteries. Indicates a coating.

도시된 바와 같이 본 발명은 양극 또는 음극 극판(30)을 회전 롤러(32,34) 사이로 통과시키면서 결착제를 코팅할 수 있도록 구성되고 있는 바, 본 실시예에서는 편의상 이를 롤 코팅법이라 칭한다.As shown, the present invention is configured to coat the binder while passing the positive or negative electrode plates 30 between the rotary rollers 32 and 34, which in the present embodiment is referred to as a roll coating method for convenience.

상기에서 회전 롤러(32,34)는 서로 마주 대하여 회전 가능하도록 배치되며, 그 수는 한쌍을 기본으로 하되 결착제의 코팅 두께 조절에 따라 다수 증감될 수 있다.The rotary rollers 32 and 34 are disposed to be rotatable with respect to each other, the number of which is based on a pair can be increased or decreased by adjusting the coating thickness of the binder.

이때, 상기 회전 롤러(32,34)의 양사이 간격은, 최종적으로 상기 극판(30)에 결착제가 코팅된 상태의 두께가 원하는 두께로 형성될 수 있도록 하는 거리를 갖는다.At this time, the interval between the two of the rotary rollers (32, 34), has a distance so that the thickness of the binder is finally coated on the pole plate 30 can be formed to a desired thickness.

아울러, 상기 회전 롤러(32,34)의 외주면은, 결착제 수용액의 함습이 가능한 섬유류 등의 재질로 형성된다.In addition, the outer circumferential surfaces of the rotary rollers 32 and 34 are formed of a material such as fibers capable of impregnating a binder aqueous solution.

한편, 상기 회전 롤러(32,34)는 그 회전시에 결착제 수용액을 공급받으면서 회전하게 되는데, 이 결착제 수용액의 공급은 상기 회전 롤러(32,34) 측에 각기 배치되어 있는 공급 노즐(36)을 통해 이루어진다.On the other hand, the rotary rollers 32 and 34 rotate while being supplied with the binder aqueous solution at the time of rotation thereof, and the supply of the binder aqueous solution is supplied to the supply nozzles 36 respectively disposed on the rotating rollers 32 and 34 side. Through).

상기 공급 노즐(36)은, 상기 회전 롤러(32,34)의 전면으로 결착제 수용액이 고루 분포될 수 있도록 고려되어 배치되며, 그 수는 상기 회전 롤러(32,34)와 마찬가지로 결착제의 코팅 두께 조절을 위하여 증감될 수 있다.The supply nozzle 36 is disposed in consideration so that the binder aqueous solution is evenly distributed to the front surfaces of the rotary rollers 32 and 34, and the number thereof is coated with the binder like the rotary rollers 32 and 34. It can be increased or decreased for thickness control.

본 실시예에서는 상기 공급 노즐(36)의 배치를 다음과 같이 즉, 상기 상측 회전 롤러(32)로는 수직 상방으로부터 결착제 수용액을 공급할 수 있도록 또한, 하측 회전 롤러(34)로는 수평 방향에서 결착제 수용액을 공급할 수 있도록 배치하고 있다.In this embodiment, the arrangement of the supply nozzle 36 is as follows, that is, the binder solution in the horizontal direction so that the binder aqueous solution can be supplied to the upper rotary roller 32 from the vertical upward, and the lower rotary roller 34 in the horizontal direction It is arrange | positioned so that aqueous solution can be supplied.

이에 상기와 같은 상태에서, 본 발명에 따라 상기 극판(30)에 결착제를 코팅하기 위해서는 우선, 상기 회전 롤러(32,34)를 구동시키게 되는데, 이때 상기 회전 롤러(32,34)는 상기한 공급 노즐(36)로부터 결착제 수용액을 공급받게 되므로, 그 외주면에 결착제를 함습한 상태에서 회전하게 된다.In such a state as described above, in order to coat the binder on the electrode plate 30 according to the present invention, first, the rotary rollers 32 and 34 are driven, wherein the rotary rollers 32 and 34 are described above. Since the binder aqueous solution is supplied from the supply nozzle 36, the binder is rotated in a state in which the binder is moistened on its outer circumferential surface.

이러한 상태로 상기 회전 롤러(32,34)가 구동되기 시작하면, 작업자는 상기 극판(30)을 상기 회전 롤러(32,34) 사이로 통과시키게 되는 바, 이때에 상기 회전 롤러(32,34)의 외주면에 함습되어 있던 결착제가 상기 극판(30)의 양측으로 묻어나게 됨에 따라, 이것으로 상기 극판(30)의 표면에는 결착제가 코팅되게 된다.When the rotary rollers 32 and 34 start to be driven in this state, the operator passes the pole plate 30 between the rotary rollers 32 and 34, and at this time, the rotary rollers 32 and 34 As the binder impregnated on the outer circumferential surface is buried on both sides of the electrode plate 30, the binder is coated on the surface of the electrode plate 30.

상기에서 상기 회전 롤러(32,34)는 제어된 회전 속도를 가지고 회전되므로, 이에 상기 극판(30)의 표면에는 사용자가 원하는 적정량의 결착제가 코팅되며, 이 코팅된 결착제는 차후의 건조 작업을 통해 건조되어 2차 전지의 양,음극판이 갖는 결착제 코팅막으로 최종 완성되게 된다.Since the rotary rollers 32 and 34 are rotated at a controlled rotation speed, the surface of the electrode plate 30 is coated with an appropriate amount of binder desired by the user, and the coated binder is subjected to a subsequent drying operation. It is dried through to finally complete the binder coating film of the positive and negative electrodes of the secondary battery.

참고로 본 실시예에서 검사한 종래의 결착제 코팅법(침적법, 스프레이 분사법)과 본 발명의 롤 코팅법에 대한 비교 항목을 아래 표에서 알아보면 다음과 같다.For reference, the comparison items for the conventional binder coating method (immersion method, spray injection method) and the roll coating method of the present invention examined in the present embodiment will be described below.

[발명의 효과][Effects of the Invention]

이상에서 살펴 본 바와 같이 본 발명에 따른 2차 전지의 극판 제조방법은, 롤 코팅방식으로 결착제의 코팅을 이루어 극판을 제조하게 됨으로써 다음과 같은 효과를 지닐 수 있다.As described above, the method of manufacturing the electrode plate of the secondary battery according to the present invention may have the following effects by manufacturing the electrode plate by coating the binder in a roll coating method.

먼저, 본 발명은 양호한 두께를 지닌 결착제 코팅막을 극판에 형성할 수 있는 효과를 지니게 되는데, 이는 결착제의 코팅량 조절을 용이하게 이룰 수 있기 때문이다.First, the present invention has the effect of forming a binder coating film having a good thickness on the electrode plate, because it is possible to easily control the coating amount of the binder.

상기에서 결착제의 코팅량 조절을 용이하게 이룰 수 있는 것은, 상기 공급 노즐의 수를 조절하여 상기 회전 롤러에 결착제 수용액 양을 조절하여 공급할 수 있다는 것과, 상기 회전 롤러의 회전 속도를 조절할 수 있다는 점에서 가능하게 된다.It is possible to easily control the coating amount of the binder in the above, by adjusting the number of the supply nozzle can be supplied to adjust the amount of binder aqueous solution to the rotating roller, it is possible to adjust the rotational speed of the rotary roller It becomes possible at the point.

또한, 본 발명에서는 항시 결착제를 수용액 상태로 공급하게 되므로, 종래 음극 극판에 결착제를 코팅시, 이 결착제에 유기용매를 혼합해야 함으로써 발생되는 문제점을 방지할 수 있게 된다.In addition, in the present invention, since the binder is always supplied in an aqueous solution state, it is possible to prevent a problem caused by mixing an organic solvent with the binder when coating the binder on a conventional negative electrode plate.

아울러, 종래의 침적법과 비교하여 본 발명은 직접 회전 롤러를 사용하여 해당 극판의 표면에 결착제를 코팅하게 되므로, 코팅시 발생되는 팽윤량이 저하된다.In addition, compared to the conventional deposition method, the present invention is to coat the binder on the surface of the electrode plate using a direct rotating roller, the amount of swelling generated during coating is reduced.

따라서, 본 발명은 양극 극판에 결착제를 코팅할 경우, 리프레싱 공정이 생략 가능하여 그 작업 공정수의 감소에 따른 작업 생산성의 향상과 함께, 침적에 의한 활물질 탈락을 막아 전지의 용량이 감소되는 것을 미연에 방지할 수 있게 된다.Therefore, in the present invention, when the binder is coated on the positive electrode plate, the refreshing process can be omitted, thereby improving work productivity due to the reduction of the number of work processes, and preventing the active material from falling off due to deposition, thereby reducing the battery capacity. It can be prevented in advance.
