You can't just throw away lithium batteries

lithium battery expansion is normal, indicating that the lithium battery aging, does not store electricity, this is normal, there is no safety risk.

Reasons for bulging:

A small amount of gas is produced in the battery during charging and is generally absorbed during discharge. Charging current is too large, often overcharging will aggravate the gas generation, so that the battery pressure increases, leading to the phenomenon of bulge. Slight swelling of the battery is allowed. Avoiding overfilling is the key to reducing bloating. Of course, the quality of mobile phone battery is also very important, now a lot of batteries on the market are shoddy, so the emergence of drum pack now is not uncommon.

How to dispose of waste batteries simply and environmentally? 1 to the neighborhood committee 2 Zhongbai seems to have recycling old batteries for gifts activities. Give it to the recycling center. Harm of waste batteries harm of waste batteries: the harm of waste batteries is mainly concentrated in the small amount of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the body through a variety of ways, long-term accumulation is difficult to eliminate, damage the nervous system, hematopoietic function and bone, and even can cause cancer. Lead: nervous system (neurasthenia, numbness of hands and feet), digestive system (dyspepsia, abdominal cramps), blood poisoning and other diseases. Mercury: altered mental state is a major symptom of mercury poisoning. Rapid pulse, muscle tremor, oral and digestive diseases. Cadmium, manganese: main damage to the nervous system. The way of environmental pollution caused by waste batteries: the components of these batteries are sealed in the battery shell during use and will not affect the environment. But after a long period of mechanical wear and corrosion, the internal heavy metals and acid and alkali leakage out, into the soil or water, will be through various ways into the human food chain. The process is briefly described as follows: pond soil microorganism animal circulating dust crop food human neuron-deposition disease. Experts believe that because battery pollution has the characteristics of long cycle, concealment, its potential harm is quite serious, improper treatment will also cause secondary pollution. According to Dr Yi-fu Yang, our country some farmers in the coastal province in the recovery of lead in lead-acid battery, because of improper recycling, throw away the waste liquid containing lead and sulfuric acid, not only cause of lead poisoning, and makes the local crops can't grow. Section 1 battery rot in the field, can make 1 square meters of permanent loss of soil utilization value; A button battery can pollute 600 tons of water, the equivalent of a person's lifetime of drinking water. A button battery can pollute 600,000 liters of water, the equivalent of a person's lifetime of drinking water. A section of battery is rotten in the ground, can make the land of one square meter loses use value, so it is not excessive to say the waste battery of a jie is "pollution small bomb" a bit. The common dry batteries we use in daily life mainly include acid zn-mn batteries and alkaline zn-mn batteries, both of which contain mercury, manganese, cadmium, lead, zinc and other metal substances. After the waste batteries are abandoned, the battery shell will slowly corrode, and the heavy metal substances will gradually infiltrate into water and soil, causing pollution. The biggest characteristic of heavy metal pollution is that it cannot be degraded in nature and can only be eliminated through purification. The harm of waste batteries is mainly concentrated on the small amount of heavy metals contained in them. The harm of metal types is manifested as manganese. Excessive manganese accumulates in the body and causes neurological dysfunction. Heavy person appears two legs hair is heavy, language is drab, expression is inflexible, feeling is indifferent, often companion has mental symptom. The salt of zinc zinc can make protein precipitate, have stimulative effect to skin film mucous membrane. There is a risk of cancer when the concentration in water exceeds 10-50 millisieverts/l, which may cause chemical pneumonia. Lead: lead mainly ACTS on the nervous system, blood circulation system, digestive system, liver, kidney and other organs, which can inhibit the anabolism process of hemoglobin, and also directly ACTS on mature red blood cells, which has a great impact on infants and children. It will lead to physical retardation of children, and chronic lead poisoning can lead to low intelligence of children. Nickel powder dissolves in the blood, participates in the internal circulation, has the stronger toxicity, can damage the central nervous system, causes the blood vessel mutation, serious causes the cancer. Mercury, it is the most worth mentioning in the heavy metal pollutants, the heavy metals, the harm to the human, does not light, long-term since, our country in the production of dry cells, to join a poisonous substances - mercury or mercury compounds, alkaline batteries in China of the mercury content of 1-5%, neutral dry cells was 0.025%, the country each year for the production of dry cells of mercury has obvious neurotoxicity, in addition to the endocrine system, immune system also has bad effects, such as in 1953, took place in Japan's kyushu minamata disease incident shocked the world, the mercury pollution to human beings. Heavy metal pollution is a threat to human health. If humans ignore the control of heavy metal pollution, they will eventually swallow the bitter fruit of their own making. Therefore, it is increasingly important to strengthen the recycling of waste batteries.

The traditional recycling idea is to separate various metal elements and make them into metal salts to sell, such as lithium carbonate and lithium oxalate. Due to its simplicity and convenience, this kind of thinking is suitable for small-scale recycling plants to adopt. Currently, a popular way of thinking is the so-called closed-loop processes, in which after a piece of battery is discarded, the manufacturer will recycle it, manufacture new batteries and put them into the market again. Although this idea sounds very attractive, as far as I know, there is no major battery manufacturer using it.
