Abstract
본 발명은 내압이 감소되고 고용량화된 니켈아연 2차전지 및 그 제조방법에 관한 것으로서, 니켈 양극판, 아연 음극판 및 격리판으로 구성되어 있는 구조체를 포함하고 있고, 개구를 갖는 케이스와 상기 케이스의 개구에 설치되어 그 개구를 폐쇄하는 캡을 구비한 니켈아연 2차전지에 있어서, 상기 캡에 0.01 내지 2.5㎏f/㎠의 압력 범위에서 안전한 성능을 갖는 폴리아미드 재질의 안전밸브가 장착된 것을 특징으로 하는 니켈아연 2차전지가 개시되어 있다. 본 발명에 따르면 니켈아연 2차전지의 내압을 크게 낮출 수 있으므로 전지의 밀폐화가 용이하고, 전지내의 감압으로 전해액의 하강 현상을 최대한 억제시킬 수 있어서 전지의 이용률 및 에너지 밀도를 증가시킬 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nickel zinc secondary battery having reduced internal pressure and high capacity, and to a method of manufacturing the same, comprising a structure including a nickel positive electrode plate, a zinc negative electrode plate, and a separator plate, and including a case having an opening and an opening of the case. A nickel zinc secondary battery having a cap installed to close the opening, wherein the cap is equipped with a polyamide safety valve having a safe performance in a pressure range of 0.01 to 2.5 kgf / cm 2. Nickel zinc secondary batteries are disclosed. According to the present invention, since the internal pressure of the nickel zinc secondary battery can be significantly lowered, the battery can be easily sealed, and the dropping of the electrolyte can be suppressed to the maximum by the reduced pressure in the battery, thereby increasing the utilization rate and energy density of the battery.
