상기한 기술적 과제를 달성하기 위한 본 고안의 일면은 2차 전지에 관한 것이다. 본 고안의 2차 전지는 서로 교호적으로 배열되는 적어도 1개의 음극판과 적어도 1개의 양극판 및 상기 음극판과 상기 양극판의 접촉을 방지하기 위한 분리판을 가지는 극판군; 및 상기 극판군을 밀봉하여 내부에 포함하는 전조 케이스를 구비한다. 그리고, 상기 극판군은 음전극판군을 구성하기 위한 상기 적어도 1개의 음극판; 양전극판군을 구성하기 위한 상기 적어도 1개의 양극판; 상기 분리판; 및 상기 양극판과 상기 음극판 및 상기 분리판의 움직임을 소정의 범위 이내에서 한정시키기 위하여, 상기 양극판과 상기 음극판 및 상기 분리판을 관통하는 고정핀으로서, 비전도성 재료로 구성되는 상기 고정핀을 구비한다.One aspect of the present invention for achieving the above technical problem relates to a secondary battery. The secondary battery of the present invention includes a pole plate group having at least one negative electrode plate and at least one positive electrode plate alternately arranged with each other, and a separation plate for preventing contact between the negative electrode plate and the positive electrode plate; And a rolling case sealing the electrode plate group and included therein. The electrode plate group may include the at least one negative electrode plate for forming a negative electrode plate group; The at least one positive electrode plate for forming a positive electrode plate group; The separator; And a fixing pin penetrating the positive electrode plate, the negative electrode plate, and the separator plate to limit movement of the positive electrode plate, the negative electrode plate, and the separator plate within a predetermined range, and including the fixing pin made of a non-conductive material. .
바람직하기로는 상기 전지 케이스는 그 부피이의 1/2 내지 2/3에 해당하는부피의 전해액을 함유한다.Preferably, the battery case contains a volume of electrolyte solution corresponding to 1/2 to 2/3 of its volume.
본 고안과 본 고안의 동작상의 잇점 및 본 고안의 실시에 의하여 달성되는 목적을 충분히 이해하기 위해서는 본 고안의 바람직한 실시예를 예시하는 첨부 도면 및 첨부 도면에 기재된 내용을 참조하여야 한다.In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the accompanying drawings.
이하, 첨부한 도면들을 참조하여 본 고안의 바람직한 일실시예에 따른 2차 전지에 대하여 상세히 설명한다.Hereinafter, a secondary battery according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 일실시예에 따른 2차전지의 구조들 중에서 극판군을 나타내는 도면이다. 도 1을 참조하면, 본 고안의 2차전지의 극판군은 양극판군을 구성하기 위한 다수개의 양극판들(101)과 음극판군을 구성하기 위한 다수개의 음극판들(103)이 서로 교호적으로 배열된다. 그리고, 상기 양극판들(101)과 상기 음극판들(103) 사이에는 분리판(105)이 배치된다. 상기 분리판(105)은 상기 양극판들(101)과 상기 음극판들(103)이 전기적으로 접촉되는 것을 방지하는 작용을 수행한다.1 is a view showing a plate group of the structure of a secondary battery according to an embodiment of the present invention. Referring to FIG. 1, in the pole plate group of the secondary battery of the present invention, a plurality of positive electrode plates 101 for constituting a positive electrode plate group and a plurality of negative electrode plates 103 for constituting a negative electrode plate group are alternately arranged. . In addition, a separation plate 105 is disposed between the positive electrode plates 101 and the negative electrode plates 103. The separating plate 105 serves to prevent the positive electrode plates 101 and the negative electrode plates 103 from being in electrical contact with each other.
그리고, 본 고안의 2차전지는 고정핀들(107)을 포함한다. 바람직하기로는 상기 고정핀들(107)은 비전도성 재료로 구성된다. 상기 고정핀(107)은 상기 양극판들(101), 상기 음극판들(103) 및 상기 분리판(105)을 관통하여 형성된다. 상기 고정핀들(107)로 인하여, 상기 양극판들(101), 상기 음극판들(103) 및 상기 분리판(105)의 움직임은 소정의 범위 이내에 한정된다. 따라서, 상기 극판들(101, 103) 및 분리판(105)의 뒤틀림은 상당히 방지될 수 있다.In addition, the secondary battery of the present invention includes fixing pins 107. Preferably, the fixing pins 107 are made of a nonconductive material. The fixing pin 107 is formed through the positive electrode plates 101, the negative electrode plates 103, and the separator plate 105. Due to the fixing pins 107, the movement of the positive electrode plates 101, the negative electrode plates 103 and the separation plate 105 is limited within a predetermined range. Thus, warpage of the electrode plates 101 and 103 and the separator plate 105 can be significantly prevented.
도 1에 도시되는 상기 극판군은 전조 케이스(도 1에 미도시)에 의하여 밀봉되어 그 내부에 포함된다.The electrode plate group shown in FIG. 1 is sealed by a rolling case (not shown in FIG. 1) and included therein.
도 2는 도 1의 극판군의 단면을 나타내는 도면이다. 도 2에 도시되는 바와 같이, 양극판들(101)과 음극판들(103) 및 분리판들(105)은 바인더 역할을 수행하는 고정핀(107)에 의하여 고정된다. 이와 같이, 고정핀(107)에 의하여, 양극판들(101)과 음극판들(103) 및 분리판들(105)이 고정됨으로써 전체적으로 뒤틀림 현상이 감소될 수 있으며, 2차전지의 성능은 현저히 개선된다.It is a figure which shows the cross section of the electrode plate group of FIG. As shown in FIG. 2, the positive electrode plates 101, the negative electrode plates 103, and the separators 105 are fixed by fixing pins 107 serving as a binder. As described above, the fixing pins 107 fix the positive electrode plates 101, the negative electrode plates 103, and the separators 105, thereby reducing the overall distortion, and the performance of the secondary battery is remarkably improved. .
도 3은 2차전지의 극판을 정면에서 바라본 도면이며, 점선으로 상기 전조 케이스(151)를 도시하였다. 본 고안에 적용되는 2차전지에서의 전해액(113)은 상기 전조 케이스에 어느 정도의 빈 공간을 남겨두는 것이 바람직하다. 실험 결과에 의하면, 상기 전해액의 부피는 전조 케이스의 1/2 내지 2/3 정도가 적당하다. 이와 같은 빈 공간으로 인하여 양극판 및 음극판 사이의 화학 반응이 원할하게 되어 2차 전지의 성능이 개선된다.3 is a front view of the pole plate of the secondary battery, and the rolling case 151 is illustrated in a dotted line. The electrolyte 113 in the secondary battery applied to the present invention is preferably to leave a certain empty space in the precursor case. According to the experimental result, about 1/2 to 2/3 of the volume of the said electrolytic solution is suitable. Due to such empty space, the chemical reaction between the positive electrode plate and the negative electrode plate is smooth, thereby improving the performance of the secondary battery.
본 고안은 도면에 도시된 실시예를 참고로 설명되었으나, 이는 예시적인 것에 불과하며, 본 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 고안의 진정한 기술적 보호범위는 첨부된 실용신안등록청구범위의 기술적 사상에 의해 정해져야 할 것이다.Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the attached utility model registration claims.
상기와 같은 본 고안의 2차전지에서는, 고정핀에 의하여, 양극판들과 음극판들 및 분리판들이 고정됨으로써 전체적으로 뒤틀림 현상이 감소될 수 있으며, 2차전지의 성능은 현저히 개선된다.In the secondary battery of the present invention as described above, by fixing pins, the positive electrode plates, the negative electrode plates and the separation plate is fixed, the overall distortion can be reduced, the performance of the secondary battery is significantly improved.
