Is making batteries harmful to the body?

Batteries are necessary in everyone's life, whether it is children's toys or various household appliances. Batteries are made up of various chemical substances, so you must be careful when using them. Especially after the battery is exhausted, the battery must not be discarded anywhere and must not be allowed to reach children. So, are batteries harmful to the human body?

1. Lithium-ion batteries are harmful to the human body. The electrolyte solution is the most harmful. The electrolyte is an organic volatile liquid and is significantly corrosive. Prolonged inhalation of volatile gases can cause damage to the respiratory tract.

2. Solute: Lithium salts are commonly used, such as lithium perchlorate (LiClO4), lithium hexafluorophosphate (LiPF6), and lithium tetrafluoroborate (LiBF?). Solvent: Since the operating voltage of the battery is much higher than the decomposition voltage of water, lithium-ion batteries often use organic solvents such as ether, ethylene carbonate, propylene carbonate, diethyl carbonate, etc.

3. Organic solvents often destroy the structure of graphite during charging, causing it to peel off and form a solid electrolyte interphase (SEI) on its surface, resulting in electrode passivation. Organic solvents also bring safety issues such as flammability and explosion.

1. Health Hazards

Routes of entry: Inhalation.

Health Hazards: Produces toxic and corrosive hydrogen fluoride in humid air. This product is highly irritating to the skin, eyes, and mucous membranes, and can cause respiratory inflammation and pulmonary edema after inhalation.

2. Toxicological Information and Environmental Behavior

Toxicity: Irritant.

Hazardous Characteristics: Generates white, corrosive and irritating hydrogen fluoride smoke in humid air. Decomposes in water and releases highly toxic and corrosive gases. Decomposes when exposed to alkali.

Combustion (decomposition) products: phosphorus oxide, phosphine, hydrogen fluoride.

②. Emergency treatment and disposal methods

1. Emergency treatment of leakage

Quickly evacuate people from the leaked contaminated area to the upwind area and immediately isolate it. For small leaks, isolate it 300 meters, and for large leaks, isolate it 450 meters, and strictly restrict entry and exit. It is recommended that emergency response personnel wear self-contained positive pressure respirators and wear anti-toxic clothing. Cut off the source of the leak if possible. Reasonable ventilation will accelerate diffusion. Leaking containers should be properly handled and repaired and inspected before reuse.

2. Protective measures

Respiratory protection: When there is a possibility of exposure to its vapor, a self-priming filter-type gas mask (full-face mask) must be worn. If necessary, wear an air respirator.

Eye protection: Protection already provided in respiratory protection.

Body protection: Wear adhesive tape anti-toxic clothing.

Hand protection: Wear rubber gloves.

Others: Smoking is strictly prohibited at the work site. Pay attention to personal hygiene.

Skin contact: Take off contaminated clothes and rinse with plenty of running water. Seek medical attention.

Eye contact: Lift the eyelids and rinse with running water or saline. Seek medical attention.

Inhalation: Move quickly away from the scene to fresh air. Keep the airways open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Fire extinguishing method: Firefighters must wear full body fire and gas resistant clothing. Cut off the gas supply. Spray water to cool the container and move it to an open area if possible. Fire extinguishing agent: dry powder, carbon dioxide.
