Is lithium battery electrolyte toxic? The harm of electrolyte to human body. The electrolytes mainly used in lithium batteries include lithium perchlorate, lithium hexafluorophosphate, etc. Lithium ion batteries are absolutely harmful to the human body. The most harmful substance is electrolyte solution, which is an organic volatile liquid with obvious corrosiveness. Inhaling volatile gases for a long time can damage the respiratory tract.

Lithium battery electrolyte is the carrier for ion transport in batteries. It is generally composed of lithium salts and organic solvents. Electrolyte plays a role in conducting ions between the positive and negative electrodes of lithium-ion batteries, ensuring their advantages such as high voltage and high specific energy. Electrolytes are generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives, and other raw materials under certain conditions and in certain proportions.

Is lithium battery electrolyte toxic?

The most harmful substance to the human body in electrolytes is the lithium salt, lithium hexafluorophosphate. This lithium salt is very domineering. It was previously said that if a palm sized skin on the surface of a person's body is corroded, it can be fatal.

The smell of electrolyte evaporation is very strong, which has a significant impact on women's pregnancy.

3. In case of electrolyte leakage in lithium batteries, personnel in the contaminated area should be quickly evacuated to a safe zone and isolated, with strict restrictions on entry and exit. Cut off the fire source. It is recommended that emergency responders wear self-contained positive pressure respirators and firefighting protective clothing. Cut off the leakage source as much as possible. Prevent entry into restricted spaces such as sewers and drainage ditches.

The harm of lithium battery electrolyte to human body

There are two types of electrolytes for lithium batteries, one is acidic electrolyte and the other is alkaline electrolyte. The main components of the former are sulfuric acid and the latter are sodium hydroxide, both of which have strong corrosiveness and their hazards are self-evident.

1. Health hazards, invasion routes: inhalation, ingestion, transdermal absorption.

Health hazards: This product is a mild irritant and anesthetic. Inhalation can cause headaches, dizziness, weakness, nausea, difficulty breathing, etc. Liquids or high concentration vapors are irritating. Oral administration stimulates the gastrointestinal tract. Long term repeated contact with the skin can be irritating.

2. Radiation, also known as radiation, refers to the phenomenon in which radio frequency waves generated by high-frequency oscillations in a circuit are emitted into space. Radiation of a certain frequency and intensity has an impact on the body.

3. The working environment of lithium batteries may contain many harmful elements, including some mercury elements, as well as other lead elements. Causing heavy metal diseases.

4. Produce white, corrosive and irritating hydrogen fluoride smoke in humid air. Decompose in water and release highly toxic and corrosive gases. Decompose when exposed to alkali.

The electrolyte of lithium batteries can mainly cause poisoning (accidental ingestion), chemical corrosion, and mechanical damage to human organs. Be careful when using it, try to avoid direct contact with the skin, and avoid eye contact and accidental ingestion, otherwise the consequences will be unimaginable. We have witnessed the power of such things in the chemistry laboratory. Especially concentrated sulfuric acid can instantly carbonize organic compounds such as cellulose and glucose, and skin cells are also composed of a large amount of organic compounds. Therefore, once in contact, the consequences are bound to be serious.

Main components of lithium battery electrolyte

The electrolyte is mainly composed of three parts: solvent, lithium salt, and additives. Among these components, although the amount of additives added is relatively small compared to other components, there are the most types of additives that can be added to one electrolyte.

solvent

The main function of solvents in electrolytes is to dissolve lithium salts. The solvents in the electrolyte mainly include cyclic carbonates (PC, EC); chain carbonates (DEC, DMC, EMC); carboxylic esters (MF, MA, EA, MA, MP, etc.).

Lithium salt

High quality lithium salts have a significant impact on the energy density, power density, wide electrochemical window, cycle life, safety performance, and other aspects of lithium batteries. The elements commonly contained in lithium salts include LiPF6, LiClO4, LiBF4, LiAsF6, etc.

additive

There are many types of additives, and different additives have different effects. Although the amount added is small, it has different impacts on the performance of lithium battery packs. The types of additives mainly include film-forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives that control the H2O and HF content in electrolytes, additives that improve low-temperature performance, and multifunctional additives.

Electrolyte has a significant impact on the overall performance of lithium-ion batteries. As the lifeblood of lithium-ion batteries, electrolyte plays a crucial role in transporting lithium ions. The quality of electrolyte directly affects the performance of lithium-ion batteries.
