Batteries and environmental protection

Published by admin at 3:51 am under battery tips

The potential contamination of used batteries has aroused widespread concern in the community. China is the world’s number one dry battery producing and consuming countries, our data show that China currently has more than 1,400 battery manufacturers in 1980, the volume of production of dry batteries surpassed the United States and the largest in the first world. In 1998, production of dry batteries in China amounted to 14 billion, while the same year the total world production of dry batteries is approximately 30 billion euros.
Such a large quantity of batteries, making it a big problem to light and that is how to make so many batteries does not affect the pollution of our environment. According to our survey, used batteries containing heavy metals and waste acid, waste alkali and electrolyte solution. If you arbitrarily discarded batteries will destroy the corruption of water, erosion of our cultural survival and the earth, our environment is facing a huge threat. If any of the cell 1 in the soil and rotting, it’s toxic form a square meter of land to lose value, throw a coin Toshiba laptop battery in water, which contains toxic substances that have killed more than 60 million liters of water pollution, equivalent to a person’s life, water, batteries containing heavy metals cadmium, lead, mercury, nickel, zinc, manganese, etc., in which cadmium, lead, mercury is a great mistake to substances in the body. Nickel, zinc and other metals, although to a certain range of concentration is a useful material, but in the environment over the limit, but also harm the human body. Waste batteries leaking heavy metals can cause rivers, lakes, sea and other bodies of water pollution, endangering the survival of aquatic and water consumption, an indirect threat to health human. Waste acid, waste alkali and so on could contaminate the electrolyte solution so that soil acidification and salinization, which Decker around us like a bomb. Therefore, collection and disposal of batteries is very important, if disposed of improperly, may be placed on the ecological environment and human health, cause serious injury.

Randomly discard used batteries is not only pollute the environment, is also a waste of resources

. Some people forget one account to the country’s annual production of 10 billion batteries, the annual consumption by 156,000 tonnes of zinc, 226.000 tonnes of manganese dioxide, 2080 tons of copper, 27,000 tonnes of chloride zinc, 79,000 tonnes of ammonium chloride, 4.3 million tons of carbon rod. Despite the advanced technology has given us the right direction, but the phenomenon of pollution in China’s battery is still not optimistic. Most waste in courtyards of China has been mixed with used batteries together in the soil over time, after the battery into decay, leaching of heavy metals, the two agencies could contaminate groundwater, they can contaminate soil and finally through a variety of ways to enter the human food chain. Biological uptake of heavy metals from the environment by biomagnification in the food chain, class by class in higher organisms tens of thousands of times richer, and then enter the body through the food chain, and economies Organ cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.
The batteries are generally divided into disposable batteries Sony laptop battery and rechargeable batteries Sony VGP-BPS2C , VGP-BPS9A battery . Disposable primary batteries, including zinc-manganese batteries (zinc and manganese dioxide) batteries containing mercury zinc (zinc oxide and mercury) and lithium batteries and several other categories. Rechargeable batteries are the main cadmium – nickel, iron – nickel, zinc – silver, zinc – air and lithium – iron sulfide and lead acid batteries and so on. Our daily life is the most frequently used zinc-manganese batteries and zinc-mercury batteries, leaving the farm pollution is mainly caused by mercury (Hg) and cadmium (Cd).
The toxicity of mercury
Mercury, which are commonly called “Mercury is liquid at room temperature, the material, can keep the battery in zinc oxide cathode, this approach to improve the shelf life of the battery. Thus, when the zinc previously used in batteries to be very cloudy almost all do a certain amount of mercury preservative. However, the chemical combination of mercury and mercury neurotoxicity of endocrine, immune system, also have a negative effect, it will trigger problems for people with speech, unsteady gait, limb paralysis, leading to generalized convulsions , mental disorders and died.
For years, China’s production of dry batteries, it is necessary to attach a toxic substance – mercury or mercury compounds. China mercury in alkaline batteries up to 1% ~ 5%, 0.025% neutral dry-cell batteries, dry batteries annually for the production of tens of tons of mercury amounted to much. With advances in technology, the battery began to implement a low-mercury and mercury-free alternatives to the mercury surface of fluoropolymers FORAFAC to prevent corrosion of zinc has achieved good results.
The mercury batteries Evo N610C battery , Evo N620C battery disposed of untreated overflow from the battery slowly in soil or water, then under the action of microorganisms, inorganic mercury can be transformed into methylmercury, meeting in the body of fish, human consumption of fish such as methylmercury, enters the cells of the human brain, the nervous systems of people have been seriously damaged in severe cases would be crazy to death. Well known Minamata disease in Japan is caused by methylmercury.
The toxicity of cadmium
Cadmium is a trace element necessary for the human body, the body of newborn babies, and there is no cadmium, but increased with age, and gradually accumulated. Cadmium with renal toxicity, which caused kidney damage is irreversible. At the same time, after a kidney damage may also be secondary osteoporosis, osteomalacia and fractures. In 1993, the International Union Against Cancer will be set at IA carcinogen cadmium level. For these reasons, many developed countries have recommended a ban on the use of nickel-cadmium batteries and nickel-metal hydride battery has been replaced by nickel-cadmium batteries, avoiding the use of cadmium. In China, the vast majority of Compaq laptop battery manufacturers still use cadmium as raw materials for manufacturing the battery, the battery being further increase the dangers. Affected by the long-term consumption of cadmium from water and contaminated food can lead to bone pain and disease, cadmium in the body, causing skeletal deformities, osteomalacia, and in the severe form of natural fractures, and even death.
The toxicity of manganese
Excessive levels of manganese accumulation in the body can cause neurological dysfunction, an early manifestation of an integrated sexual dysfunction, the emergence of more heavy monotonous speech, sad expression, emotional indifference, accompanied by psychological symptoms .
Lead toxicity
Driving a major role in the nervous system, hematopoietic system, digestive system and liver, kidneys and other organs, can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells, for infants, children much younger, it will lead to physical development of children, a chronic lead late in the mental retardation of children first.
The toxicity of nickel
Nickel powder dissolved in the blood, to participate in the movement of the body, with a high toxicity, may damage the central nervous system, causing abnormal blood vessels, severe cases, cause cancer.
The toxicity of zinc
Zinc is an essential element of the human body, less toxic, 1000 mg of zinc sulfate orally only to those with acute intoxication, but inhalation of dust zinc oxide may cause poisoning. The symptoms include generalized fatigue, muscle pain, difficulty breathing, vomiting, diarrhea, DELL laptop battery severe heart weakness, prostration, convulsions, death. Zinc sulphate, zinc chloride penetrated the mucous membrane of the skin may produce dermatitis and ulcers. Zinc to fish and aquatic toxicity of the toxic people, if the requirements of water quality for fish in the water content of zinc per liter should not exceed 0.1 mg.
Recycling of waste batteries
Waste batteries may be small, large Queshen cons. However, due to pollution, waste piles are not as waste, air and water pollution, as would any sensory think she has a big secret, so do not receive the attention. At present, battery production and consumption of China to become a great country, and the batteries of pollution is an urgent need to address a major environmental problem.
According to environmental experts, recovery of waste batteries per 1000 grams of metal, which are 82 grams of mercury, 88 grams of cadmium, we can say that eliminating the recycling of waste batteries s The address not only the sources of pollution, but also to achieve the recycling of resources. In developed countries the recycling of batteries and use very seriously. Many countries in Western Europe, not only in stores, but also directly on the street are equipped with a special box for recycling batteries and accumulators are 95% of the material can be recycled, especially in high recovery of valuable metals. Such as foreign secondary lead industry developed rapidly, lead to short-term 55% of production comes from reclaimed lead. The secondary lead industry in the treatment of the regeneration of waste lead-acid batteries account for a substantial portion. 100 kg of waste lead-acid batteries can be recycled 50 to 60 kilograms of lead. Cadmium batteries for the regeneration of technology waste treatment abroad, have been more mature to deal with 100 kilograms of waste recycling cadmium batteries Latitude X300 battery, XPS M140 battery, XPS M1210 battery of about 20 kg of metal cadmium, mercury batteries are mainly used to treat environmentally sound ways to prevent environmental pollution. However, there is in this area of management rather low.
