Description
본 발명은 리튬계 배터리의 화재 진압용 방재액에 관한 것으로, 더욱 상세하게는 리튬계 배터리의 화재 발생시 생성되는 독성물질을 중화하며 화학발열반응을 억제하는 리튬계 배터리 화재진압용 방재액에 관한 것이다.The present invention relates to a disaster prevention solution for extinguishing a fire in a lithium-based battery, and more particularly, to a disaster prevention solution for extinguishing a fire in a lithium-based battery that neutralizes toxic substances generated in the event of a fire in a lithium-based battery and suppresses a chemical exothermic reaction. .
4차 산업혁명시대가 도래함에 따라 배터리의 중요성이 더 부각되고 있다. 그 중 리튬계 배터리는 높은 에너지 밀도, 긴 수명, 높은 용량, 높은 출력, 낮은 자가 방전의 특징을 가지고 있어 전기자동차나 에너지저장장치(ESS, Energy Storary System), IT 기기, 가전제품 분야에 많은 변화를 가져왔다.As the 4th industrial revolution era arrives, the importance of batteries is becoming more prominent. Among them, lithium-based batteries have the characteristics of high energy density, long lifespan, high capacity, high output, and low self-discharge, so there are many changes in the fields of electric vehicles, energy storage systems (ESS), IT devices, and home appliances. brought
리튬계 배터리는 높은 전압을 형성하는 리튬염 전해액을 사용하는 이차전지로서 일반적으로 양극, 음극, 분리막, 전해액으로 구성된다. 특히 리튬계 배터리는 휘발성이 있는 유기성 전해액이 주로 사용되는데, 유기성 전해액은 반응성이 높아 일반적으로 휘발유보다 연소가 용이하기 때문에 화재의 위험성이 높다.A lithium-based battery is a secondary battery using a lithium salt electrolyte that forms a high voltage, and is generally composed of a positive electrode, a negative electrode, a separator, and an electrolyte solution. In particular, lithium-based batteries mainly use volatile organic electrolytes. Organic electrolytes are highly reactive and generally more easily combustible than gasoline, so the risk of fire is high.
리튬계 배터리에서 화재가 발생하면 불화수소(HF), 플루오르화포스포릴(POF3)와 같은 독성물질이 다량으로 발생한다. 불화수소는 가열 시, 독성 흄(fume)을 형성하며 금속과 접촉 시 수소가스를 발생시키기 때문에 화재가 확대되거나 폭발이 발생할 수 있다. 이러한 불화수소는 물에 대한 용해도가 매우 높기 때문에 리튬계 배터리에서 화재가 발생하면 물을 분사하여 불화수소의 확산을 막을 수 있다. 하지만 물은 전체적인 화학 발열반응을 가속하기 때문에 독성물질을 중화하며 화학발열반응을 억제하는 리튬계 배터리 화재진압용 방재액의 개발이 필요하다.When a fire occurs in a lithium-based battery, a large amount of toxic substances such as hydrogen fluoride (HF) and phosphoryl fluoride (POF 3 ) are generated. Hydrogen fluoride forms toxic fumes when heated and generates hydrogen gas when in contact with metals, which can spread a fire or cause an explosion. Since hydrogen fluoride has a very high solubility in water, when a fire occurs in a lithium-based battery, the diffusion of hydrogen fluoride can be prevented by spraying water. However, since water accelerates the entire chemical exothermic reaction, it is necessary to develop a disaster prevention liquid for lithium-based battery fire suppression that neutralizes toxic substances and suppresses the chemical exothermic reaction.
따라서 본 발명의 목적은 독성물질을 중화하며 화학발열반응을 억제하는 리튬계 배터리 화재진압용 방재액을 제공하기 위한 것이다.Accordingly, an object of the present invention is to provide a disaster prevention liquid for extinguishing a fire in a lithium-based battery that neutralizes toxic substances and suppresses a chemical exothermic reaction.
