Title (EN) ZINC-AIR SECONDARY BATTERY
(FR) BATTERIE RECHARGEABLE ZINC-AIR
(KO) 공기-아연 이차전지
Abstract:
(EN) One embodiment of the present invention relates to a zinc-air secondary battery, more specifically to a zinc-air secondary battery comprising: a positive electrode; a negative electrode; a separation membrane interposed between the positive and negative electrodes; and electrolyte accommodated between the positive and negative electrodes and submerging a part of the positive electrode, wherein at least one side of the separation membrane is provided with a potassium ion (K+) anti-diffusion layer. According to the present invention, potassium ions moving to the positive electrode side and precipitating can be stably blocked, and consequently, the destruction of a carbon layer due to the potassium ion precipitation can be prevented.
(FR) Un mode de réalisation de la présente invention concerne une batterie rechargeable zinc-air, plus spécifiquement une batterie rechargeable zinc-air comprenant: une électrode positive; une électrode négative; une membrane de séparation placée entre les électrodes positive et négative; et un électrolyte logé entre l'électrode positive et l'électrode négative et immergeant une partie de l'électrode positive, au moins un côté de la membrane de séparation étant pourvu d'une couche anti-diffusion (K+) d'ions de potassium. Selon la présente invention, des ions de potassium se déplaçant vers le côté électrode positive et se précipitant peuvent être bloqués de manière stable, et par conséquent, la destruction d'une couche de carbone due à la précipitation d'ions de potassium peut être evitée.
(KO) 본 발명의 일 양태는 공기-아연 이차전지에 관한 것으로, 보다 구체적으로 양극; 음극; 상기 양극 및 음극 사이에 개재되는 분리막; 및 상기 음극과 분리막 사이에 수용되고, 양극의 일부를 함침하는 전해액;을 포함하되, 상기 분리막의 적어도 한 쪽 면에 칼륨이온(K+) 확산 방지층이 형성되어 있는 것을 특징으로 한다. 본 발명에 의하면, 칼륨 이온이 양극 측으로 이동하여 석출되는 것을 안정적으로 차단할 수 있으며, 이에 따라 칼륨 이온의 석출에 의한 탄소층의 파괴를 방지할 수 있다.
