Research progress of water mist fire extinguishing technology and its application in battery fires

Due to its high efficiency and non-pollution, water mist fire extinguishing technology has attracted increasing interest and attention from various fire protection fields, including library fire safety, traf-fic hub station fire safety, ship fire safety and spacecraft fire safety. To support research and development of water mist fire extinguishing technology and its application in the field of battery fires, this paper begins by detailing the mechanisms by which water mist extinguish fires. The influence of internal and external factors on the fire suppression effectiveness of water mist is then discussed, such as water mist characteristics, additives, obstacles, ventilation conditions, fuel types and flame scales, followed by a review of researches of water mist technology in battery fires. In the final part, based on current research tendency, the paper provides future development direction and research ideas of water mist fire extinguishing technology and foresees the development prospects of its application in the battery fire field.
