Abstract

본 발명은 아연 및 산화 아연을 음극 활물질로 사용하는 알카리∼아연 2차전지에 관한 것으로서, 좀더 상세하게는 알카리∼아연 2차전지에 있어서, 아연극이 집전체, 상기 집전체 외부에 1차 활물질층 및 상기 1차 활물질층의 외부에 다공도가 더 큰2차 활물질층으로 이루어진 알카리∼아연 2차전지를 제공하므로써 전극 반응면적의 감소를 억제, 활물질의 이용률등을 향상시켜 방전용량의 저하 및 전극표면의 부동태화를 방지하고 전지의 충방전 싸이클 수명이 향상된 알카리∼아연 2차전지에 관한 것이다.The present invention relates to an alkali-zinc secondary battery using zinc and zinc oxide as a negative electrode active material. More particularly, in an alkali-zinc secondary battery, a zinc electrode is a current collector and a primary active material outside the current collector. By providing an alkali-zinc secondary battery composed of a secondary active material layer having a higher porosity outside the layer and the primary active material layer, the reduction of the electrode reaction area is suppressed, the utilization rate of the active material is improved, and the discharge capacity is lowered and the surface of the electrode is improved. The present invention relates to an alkali-zinc secondary battery which prevents passivation of the cell and improves the charge / discharge cycle life of the battery.
