Abstract

본 발명은 개방형 아연 2차전지에 관한 것으로, 좀 더 상세하게는 개방형 알카리 아연 2차전지에 있어서, 알카리 전해액에 용존산소 억제제인 유수히드라진이 첨가된 것으로 이루어지므로써 장기간 방치할 경우 용존산소에 의한 아연전극의 부식이 억제되어 자기 방전특성이 향상되며, 전해액내에 존재하는 용존산소에 의한 세퍼레이터의 부식이 억제되어 전지의 성능 및 싸이클 수명이 향상된 개방형 알카리 아연 2차전지에 관한 것이다.The present invention relates to an open zinc secondary battery, and more particularly, to an open alkaline zinc secondary battery, in which the dissolved electrolyte oxygen-containing hydrazine is added to the alkaline electrolyte solution, when dissolved for a long time, The present invention relates to an open-type alkaline zinc secondary battery in which corrosion of a zinc electrode is suppressed to improve self-discharge characteristics, and corrosion of a separator due to dissolved oxygen present in an electrolyte is suppressed to improve battery performance and cycle life.
