Is the smoke of the lithium ion battery harmful to the human body after the explosion?

For daily-use lithium-ion batteries, the shorter the battery life may be due to the reduced life. If the charging time is the same as before, but the battery runs out after less than 10 minutes of use, this battery will definitely not work. When buying a new machine a long time ago, the promoter will tell you that the first three 12-hour charging and activation of the new machine will actually not have any effect. Because, a long time ago, lithium-ion batteries had to be deep-discharged and deep-charged three times in order to maximize the power of the battery, but now the new-type lithium-ion battery has no memory effect, so don't over-discharge and over-charge. In the event of a fire and explosion, lithium ion batteries have the following important pollutants that will diffuse into the environment: 1. Lithium cobalt oxide, as the positive electrode of the battery, may diffuse into the air in the form of dust powder in the accident. There is a certain degree of carcinogenicity, and the relevant occupational exposure standards are relatively low, which may cause a certain degree of environmental pollution to the accident site in a short time. 2. Fluoride (LiPF6, LiAsF6), as the electrolyte of the battery, may form hydrogen fluoride HF at the accident site, and there is a certain corrosive and toxic gas. 3. Organic solvent (NMP), the full name of N-methylpyrrolidone, is used as a dispersant for the positive electrode of the battery. The organic solvent is a dangerous chemical with certain irritation and reproductive toxicity, and is flammable (flash point 86℃). At the scene of the accident May form harmful vapors. 4. Black smoke and toxic gases from the process of burning construction, decoration materials and raw and auxiliary materials. 5. Fire-fighting wastewater from the process of fire-fighting and fire-fighting, as well as sewage from rain washing.
