How old is the waste of lithium-ion batteries and lead-acid batteries? Everyone understands that the waste battery is quite troubles, and throws a lot of damage to the environment. In the solution of waste lithium-ion batteries and lead-acid batteries, recycling is one aspect, and there is also a source to eliminate this Pollution. With the improvement of people's understanding, the pollution problems caused by waste batteries will gradually handle the pollution problems caused by the establishment of a comprehensive and effective recycling network and system.

What is the harm of waste lithium ion batteries? Lithium-ion batteries are not harmful to the human body and the environment during normal use, but the scrapped lithium-ion battery will cause harm to the environment, then through environmental use to surrounding organisms and human body. This is important because the chemicals such as lithium hexafluorophosphate contained in the lithium ion battery will cause organic pollution to the environment. In addition, it contains heavy metal elements, which will also cause harm to the environment.

For example, in the solution to the cancer ion battery, it is first to be pre-resolved, including discharge, dismantling, pulverization, sorting; after dismantling, the plastic and the iron housing can be recovered; then the electrode material is leached, Acid is immersed, after multiple procedures, then extract. The electrolyte of waste lithium-ion batteries and its transformation products such as LiPF6, LiASF6, LiCF3S03, HF, P201, etc. Ion batteries are sent to qualified places to solve uniform, don't be discarded freely.

Lithium-ion batteries contain a variety of toxic substances, with strong corrosive and pollution. In addition, the waste lithium-ion battery electrolyte contains very poisonous, flammable and explosive, corrosive electrolyte and organic solvent. If you discard or leave, you will cause pollution and damage to the atmosphere, water, soil.

Moreover, the electrolyte leaks and temperatures can cause dangerous batteries and fires, and the pen is threatened by people's lives and property. In addition, the waste lithium-ion battery will sprout a series of pollutants during the rupture sort, high temperature heat solution prevision, such as the analysis of the electrolyte, the thermal solution of plastic film, the rupture dust, waste residue, etc., these pollutants are not only For the atmosphere, the water body causes severe pollution and has serious corrosive resistance to the equipment.

At the same time, the various acid-base impregnants, extractants, and active additives, etc., which are added, not only the cost of recovering process flow, resulting in waste and resources. New energy consumption, and a large number of wastewater, exhaust gas, waste residue, waste additives, etc.

The harm of waste batteries The harm of used batteries is important to the small amount of heavy metals contained therein, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various means, long-term accumulation is difficult to exclude, impair nervous system, hematopoietic function and bones, and even cancer. 1.

Mercury (HG) has a distinct neurotoxicity, and there is also an adverse effect on endocrine systems, immune systems, etc., which will cause pulse, muscle fibrillation, oral and digestive system disease; 2. Cadmium (CD) elements enter into various routes In the human body, long-term accumulation is difficult to exclude, damage the nervous system, hematopoietic function and bones, and can even cause cancer; 3.

Lead (PB) can cause neurasthenia, hand and foot numbness, indigestion, abdominal colic, blood poisoning and other lesions; manganese Will hazard the nervous system. How big is the hazard of waste lead acid? The harmful substances in lead-acid battery processing include lead, sulfuric acid, carbon black, sulfur, asphalt, etc. Among them, the number of people who contact lead and sulfuric acid is also very serious about the harm of the operator.

my country has currently listed lead poisoning, carbon black and lung, and tooth alcoholic diseases in the list of legal occupational diseases. 1. Lead invasive pathway and intrusion path of harm lead and its compounds is important to respiratory tract, followed by digestive tract, intact skin can't absorb.

2. Invasive pathway of sulfuric acid and the hazardous sulfuric acid are invasive pathways. It is important that sulfate is inhaled by respiratory tract, causing damage to the operator's teeth and upper breathing.

At present, the statutory vocational disease list is a diamondic disease, and although the restricted inflammation of the respiratory tract is not included in the legal occupational disease, it should also be concerned. 3. Carbon black and asphalt invasive pathway and harm carbon black are important to cause harm to the human body through respiratory and skin.

The human body is inhaplusing carbon black, and the lung group has a fibrosis, so that the lung tissue is gradually hardened, and the normal respiratory function is lost, causing carbon black dust. All processing processes of lead-acid battery processing companies have different degrees of harmful substances primarily with lead dust, lead smoke, and small partial steps and sulfuric acid spillage. The above is the waste of lithium-ion batteries and lead-acid batteries.

Recycling of waste batteries should have strict procedures, the internationally available waste battery solutions have roughly three types: solidification is deeply buried, deposited in wasteling wells, recycling. Establish a sound and effective recycling network and system, enhance publicity and guidance, scientifically recognize the impact of waste batteries on the environment, is a big thing in the country. .
