1. Lithium-ion batteries are harmful to the human body. The most harmful is the electrolyte solution, the electrolyte is an organic volatile liquid, and has obvious corrosiveness. Long-term inhalation of volatile gas has damage to the respiratory tract;

2. If you are working on battery cells, the materials inside the cells are harmful to the human body and it is not recommended to go. You should wear a gas mask or mask when working. The work environment may contain many harmful elements, some mercury elements are common, as well as other lead elements. Causing heavy metal diseases.

3. Radiation. The so-called radiation refers to the phenomenon of radio frequency waves emitted into space due to high-frequency oscillations in circuits. Radiation of a certain frequency and intensity has an impact on the body.

4. The lithium salt which poses a great threat to human health in the electrolyte of lithium-ion batteries is the lithium hexafluorophosphate. It is heard that if a person's skin surface is corroded to the size of a palm, it can be fatal.

5. The volatile smell of electrolyte is very strong, and this smell has a significant impact on women's pregnancy.

When electrolyte leakage occurs, personnel should be evacuated from the contaminated area to a safe area, and isolated, with close confinement of entry and exit. Cut off the combustion source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the leakage source as soon as possible. Prevent entry into restricted spaces such as sewers and drainage ditches.
