Abstract

본 발명은 2차전지에 관한 것으로서, 양극, 음극, 상기 양극과 음극 사이에 배치되는 절연성 격리판 및 전해액의 전지요소를 내장하는 캔, 상기 전지요소를 밀폐하며 배기공을 갖는 밀봉판, 상기 배기공의 밀폐를 위해 상부에 설치되는 안전변, 및 상기 안전변의 상부에 구비되어 양극 단자를 형성함과 동시에 덮개가 되는 캡을 포함하는 2차전지에 있어서, 상기 밀봉판의 상부로부터 전지의 외부에 이르는 곳 사이의 어느곳에 밀봉판의 배기공을 통하여 누출되는 전해액을 흡수할 수 있는 흡수수단을 구비하는 2차전지를 제공한다. 과충전, 과방전시에 이상반응으로 인하여 발생되는 가스로 건지 내압이 상승하게 되고 이 가스의 외부누출시 수반되는 전지누액의 외부누출이 방지되어 누액에 의한 제품손상이 방지된다.The present invention relates to a secondary battery, comprising: a positive electrode, a negative electrode, an insulating separator disposed between the positive electrode and the negative electrode, a can containing a battery element of an electrolyte, a sealing plate sealing the battery element and having an exhaust hole; A secondary battery comprising a safety valve installed at an upper portion for sealing a ball, and a cap provided at an upper portion of the safety valve to form a positive electrode terminal and covering at the same time, from the top of the sealing plate to the outside of the battery. Provided is a secondary battery provided with absorbing means capable of absorbing an electrolyte solution leaking through an exhaust hole of a sealing plate at any place between the places. As the gas generated by abnormal reaction during overcharging and overdischarging increases the internal pressure of the battery, the external leakage of battery leakage is prevented when the external leakage of this gas is prevented, thereby preventing product damage by leakage.
