The electrolyte in a lithium-ion battery is the carrier for ion transport within the battery. It is generally composed of lithium salts and organic solvents. The electrolyte acts as a conductor of ions between the positive and negative electrodes of a lithium-ion battery, ensuring the battery's advantages such as high voltage and high specific energy. The electrolyte is typically prepared under specific conditions and in specific proportions from high-purity organic solvents, lithium salts, and necessary additives.
There are two types of electrolytes for lithium-ion batteries: acidic electrolytes and alkaline electrolytes. The main components of the former are sulfuric acid and the latter are sodium hydroxide. Both are highly corrosive, and their hazards are self-evident.
1. Health hazards and routes of entry: inhalation, ingestion, and skin absorption.
Health Hazards: This product is a mild irritant and anesthetic. Inhalation may cause headache, dizziness, weakness, nausea, and difficulty breathing. The liquid or high concentration of vapor is irritating. Oral ingestion may irritate the gastrointestinal tract. Prolonged and repeated skin contact may cause irritation.
2. Radiation: Radiation refers to the phenomenon of radio frequency waves emitted into space from high-frequency oscillations in a circuit. Radiation of a certain frequency and intensity can have an impact on the body.
3. The working environment of lithium-ion batteries may contain many harmful elements, such as mercury, which is relatively common, as well as other elements like lead. These can lead to heavy metal-related illnesses.
4. It produces a white, corrosive, and irritating hydrogen fluoride fumes in humid air. It decomposes in water, releasing highly toxic and corrosive gases. It decomposes in alkaline environments.
Lithium-ion battery electrolytes can cause poisoning (if swallowed), chemical corrosion, and mechanical damage to human organs. Use with extreme caution, avoiding direct skin contact, and never allow it to get into eyes or be swallowed; otherwise, the consequences could be dire. We have witnessed the power of such substances in chemical laboratories. Concentrated sulfuric acid, in particular, can instantly carbonize organic matter such as cellulose and glucose. Since skin cells are also composed of a large number of organic compounds, contact with these substances will inevitably have severe consequences.
