Description

공기-아연 이차전지 모듈Air-Zinc Secondary Battery Module
본 발명은 수용액 저장부에 수용된 수용액의 워터 헤드(water head)에 무관하게 공기-아연 이차전지 유닛으로 수용액을 효율적으로 공급할 수 있는 공기-아연 이차전지 모듈에 관한 것이다.The present invention relates to an air-zinc secondary battery module capable of efficiently supplying an aqueous solution to an air-zinc secondary battery unit irrespective of the water head of the aqueous solution contained in the aqueous solution storage unit.
전기 화학 전력원은 전기 에너지가 전기화학 반응에 의해서 생성될 수 있는 장치를 의미하며, 공기-아연 이차전지도 상기 전기 화학 전력원에 해당한다. 공기-아연 이차전지는 방전 중에 아연산화물로 변환되는 아연겔로 이루어진 아연겔 음극부를 채용하고, 양극으로는 물 분자를 포함하고 있는 투과성의 막으로서, 공기 중 의 산소와 접촉하여 수산화 이온을 발생시키는 막 형태의 공기 양극부를 채용한다.Electrochemical power source means a device in which electrical energy can be generated by an electrochemical reaction, and an air-zinc secondary battery also corresponds to the electrochemical power source. The air-zinc secondary battery adopts a zinc gel negative electrode portion made of zinc gel which is converted into zinc oxide during discharge, and is a permeable membrane containing water molecules as the positive electrode, which generates hydroxide ions in contact with oxygen in the air. The air anode in the form of a membrane is adopted.
이와 같은 공기-아연 이차전지는 종래의 수소 연료 전지에 비해 많은 장점들이 있다. 특히, 아연과 같은 연료가 금속이나 그 산화물로서 풍부하게 존재할 수 있기 때문에 공기-아연 이차전지로부터 제공된 에너지 공급이 가시적으로 고갈되지 않는 장점이 있다. 또한, 종래의 수소 연료 전지들은 재충진이 요구되는데 반해 공기-아연 이차전지는 전기적으로 재충전하여 사용할 수 있고, 통상적인 연료 전지들(<0.8V)보다 높은 출력전압(1.4 V)을 전달할 수 있는 이점이 있다.Such air-zinc secondary batteries have many advantages over conventional hydrogen fuel cells. In particular, there is an advantage that the energy supply provided from the air-zinc secondary battery is not visually depleted because fuels such as zinc can be present in abundance as metals or oxides thereof. In addition, while conventional hydrogen fuel cells require recharging, air-zinc secondary cells can be used to be electrically recharged and can deliver an output voltage (1.4 V) higher than that of conventional fuel cells (<0.8 V). There is an advantage.
한편, 공기-아연 이차전지는 방전이 지속될수록 물을 소모하게 되며, 이로 인해 음극부 내에 존재하는 전해액 중 물의 손실이 발생하게 된다. 따라서, 음극부 내 지속적인 물 보충이 필요하며, 만약 물의 보충이 이루어지지 않게 된다면 전해액 중 수산화칼륨(KOH)의 농도가 지나치게 상승하게 되고, 결국 양극부 내에 칼륨 고체가 석출되게 되어, 양극부의 파열을 초래하고 전지의 성능을 현저히 저하시키는 원인으로 작용한다.On the other hand, the air-zinc secondary battery consumes water as the discharge continues, resulting in the loss of water in the electrolyte solution present in the negative electrode. Therefore, continuous water replenishment in the cathode part is required, and if water is not replenished, the concentration of potassium hydroxide (KOH) in the electrolyte is excessively increased, resulting in precipitation of potassium solids in the anode part, resulting in rupture of the anode part. This causes a significant decrease in battery performance.
따라서, 공기-아연 이차전지는 전해액을 지속적으로 공급할 수 있는 구조를 포함하여 공기-아연 이차전지 모듈을 형성하며, 도 1은 종래의 공기-아연 이차전지 모듈에 대해 도시한 것이다.Accordingly, the air-zinc secondary battery forms an air-zinc secondary battery module including a structure capable of continuously supplying an electrolyte solution, and FIG. 1 illustrates a conventional air-zinc secondary battery module.
도 1에 의하면, 기존의 공기-아연 이차전지 모듈은 복수의 공기-아연 이차전지 유닛(100), 수용액 저장부(200) 및 수용액 공급배관(300)을 포함하며, 상기 수용액 저장부(200)에서 공기-아연 이차전지 유닛(100)의 음극부(130)로 수용액을 지속적으로 공급하여 보충해주는 구조로 되어 있다. 하지만, 도 1에 의하면 수용액 저장부(200)에 수용되어 있는 수용액(230)의 수위가 공기-아연 이차전지 유닛의 각각에 포함되어 있는 아연 겔(131)의 높이 보다 낮게 되면, 상기 공기-아연 이차전지 유닛(100)의 각각에 포함되어 있는 아연 겔(131)을 충분히 젖도록 할 수 없는 문제가 발생할 수 있다. 다시 말해, 수용액 저장부(200)에 수용된 수용액의 워터 헤드(water head)의 정도에 따라 공기-아연 이차전지 유닛(100)의 각각에 포함되어 있는 아연 겔(131)을 전체적으로 고르고, 충분하게 적실 수 없는 문제가 생길 수 있으며, 아연 겔(131)이 부분적으로 젖지 않게 되는 상황이 발생하면 공기-아연 이차전지 유닛(100)의 방전 성능도 현저하게 저하되는 문제로 이어지게 된다.According to FIG. 1, the conventional air-zinc secondary battery module includes a plurality of air-zinc secondary battery units 100, an aqueous solution storage unit 200, and an aqueous solution supply pipe 300, and the aqueous solution storage unit 200. In the air-zinc secondary battery unit 100 has a structure that is supplemented by continuously supplying an aqueous solution to the negative electrode portion 130. However, according to FIG. 1, when the water level of the aqueous solution 230 accommodated in the aqueous solution storage unit 200 is lower than the height of the zinc gel 131 included in each of the air-zinc secondary battery units, the air-zinc A problem may occur in that the zinc gel 131 included in each of the secondary battery units 100 may not be sufficiently wetted. In other words, the zinc gel 131 included in each of the air-zinc secondary battery units 100 may be selected as a whole according to the degree of the water head of the aqueous solution contained in the aqueous solution storage unit 200 and sufficiently wet. Problems may occur, and the zinc gel 131 may be partially wetted, leading to a problem in that the discharge performance of the air-zinc secondary battery unit 100 is also significantly reduced.
