What are the hazards of lithium battery electrolyte to the human body and too little electrolyte injection?

The harm of lithium battery electrolyte to human body Lithium battery is harmful to human body. The most harmful is the electrolyte solution. The electrolyte is an organic and volatile liquid, and it is obviously corrosive. Inhalation of volatile gas for a long time can damage the respiratory tract. Invasion route: inhalation, ingestion, transdermal absorption. Health hazards: This product is a mild irritant and anesthetic. It may cause headache, dizziness, weakness, nausea, dyspnea, etc. after inhalation. Liquid or high-concentration vapor is irritating. Oral irritation of the gastrointestinal tract. Long-term repeated contact with the skin is irritating. The most harmful to the human body in the electrolyte is the lithium salt and lithium hexafluorophosphate among them. It has been heard before that if a palm-sized skin on the surface of the human body is corroded, it can be fatal, so now electrolyte manufacturers pay great attention to these safety controls. The composition of lithium battery electrolyte is mainly divided into electrolyte and solvent. The electrolyte is usually lithium salt. For example, LiFP6 lithium salt will react with water to form hydrofluoric acid. Hydrofluoric acid is a huge harm to the human body. The higher the concentration, the greater the damage. If the electrolyte gets on the human body, it should be cleaned in time with a lot of water. The volatile odor of lithium battery electrolyte is very heavy, and this odor has a great impact on women's pregnancy. Electrolyte leakage should quickly evacuate personnel from the leaked contaminated area to a safe area, and isolate them, strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains. The harm of too little electrolyte injection of lithium battery 1. Less electrolyte and less lithium ion transmission path leads to increase of internal resistance. The internal water content of the lithium battery exceeds the standard, and the internal short-circuit polarization of the battery leaks, causing the lithium sheet to react and make the lithium sheet rise. Drum; 2. The internal resistance is high and the extreme capacity is exerted. The negative lithium-ejection cycle performance is poor, and the cycle period is easy to swell. If the cycle is less, the cycle is too small, and the initial cycle is poor; 3. The lithium battery electrolyte is in the sealed battery , It is easy to leak, the efficiency is affected, and the life span is reduced. If the amount of liquid injected is small, the resistance of the electrolyte will increase, which will affect the primary efficiency and reduce the life. The water content of the electrolyte importantly affects the material properties of the lithium ion transfer electrode and reduces the capacity life; 4. The vent of the charged electrolyte overflows and pollutes the lithium battery The outer casing is self-discharged and corrodes the lithium battery holder and its parts. The vent should be unblocked, otherwise the charging hydrogen gas battery will burst; 5. First, look at the negative electrode sheet should be golden yellow, golden yellow gradually faded and white crystals appear White due to the increase in the number of lithium ion negative plates oxidized and turned white.
