What are the hazards of lithium-ion batteries? How much harm does battery pollution bring? In today's society, the demand for batteries is constantly increasing, resulting in a significant increase in battery production. Some uncivilized people are accustomed to littering discarded old batteries. Discarded batteries can bring great hidden dangers to humans and the environment, and have extremely adverse effects on the sustainable development of ecological civilization. Below, the editor will talk about the hazards of lithium-ion batteries? How much harm does battery pollution bring?

The cycle life, weight to capacity ratio, lightweight, and memoryless advantages of lithium-ion batteries have gradually replaced lead-acid batteries and are increasingly being used in electric bicycles. However, as lithium-ion batteries are emerging batteries, many consumers or businesses have little understanding of lithium-ion batteries. Therefore, when lithium-ion batteries malfunction during use, they are replaced, which greatly increases costs for consumers and causes waste of social resources.

What are the hazards of lithium-ion batteries?

1. Lithium ion batteries are absolutely harmful to the human body, with the electrolyte solution being the most harmful. The electrolyte is an organic and volatile liquid, and it has obvious corrosiveness. Long term inhalation of volatile gases can damage the respiratory tract and cause respiratory diseases.

2. When the lithium-ion battery reaches a fully charged state, the insertion reaction of lithium ions in the negative electrode leads to the deposition of lithium metal on the surface of the negative electrode, and the solvent is oxidized; As the temperature of lithium-ion batteries increases, reactions between metallic lithium and solvents, as well as between lithium embedded carbon and solvents, occur one after another, leading to battery ignition and explosion.

3. Lead in lithium-ion batteries can cause osteoporosis, and lithium-ion batteries generally survive in nitrogen-free spaces. If left in that space and come into contact with water, they will decompose and produce a pungent odor.

When a collision accident occurs, the collision safety of power lithium-ion batteries means that they will not pollute the environment, harm dangerous voltages, toxic gases, high temperatures, or fires to passengers, pedestrians, and rescue personnel.

How much harm does battery pollution bring?

1. Waste batteries contain a lot of heavy metals and electrolytes, which will penetrate into soil and groundwater, causing great harm to the ecological environment. Moreover, these heavy metals cannot degrade on their own in nature and can only migrate. Once they migrate to water or soil, they will cause pollution to water and soil, resulting in the inability of water and soil to purify themselves.

2. The pollution intensity of a discarded mobile phone battery is 100 times that of a regular dry battery, and it can seriously pollute 60000 liters of water. If discarded mobile phones are transported to the landfill for incineration, the plastic casing will also contain toxic substances containing chlorine, and even the first level carcinogen dioxin. The printed circuit board and casing of mobile phones contain bromine flame retardants, which can damage human health, cause thyroid dysfunction, endocrine disorders, and neurological and immune system problems.

3. There are five substances in the natural environment that pose the greatest threat to soil, and batteries contain three of them: mercury, lead, and cadmium. Mercury is mercury, which is a highly carcinogenic and toxic substance. Scientists have found that the toxicity of mercury can have adverse effects on the immune system, endocrine system, and other systems, making children more vulnerable.

4. Cadmium in batteries is a highly toxic heavy metal, with important symptoms such as osteomalacia, anemia, and emphysema, and is likely to paralyze the human body. If mines or wastewater containing cadmium pollute the grass, food, and soil on both banks and rivers, and slowly accumulate in the bones and kidneys through the food chain, it will replace calcium in the bones, causing severe softening or even bone fractures. The toxicity of cadmium is potential.

At present, there is no good solution for the recycling and treatment of lithium-ion batteries for mobile phones. On the one hand, it is hoped that a waste mobile phone battery recycling system can be formed quickly; On the other hand, users should develop the habit of not littering discarded mobile phone batteries and actively cooperate with relevant departments to effectively carry out recycling and disposal work.
