Batteries become a source of out-of-control pollution. Why are the big consumers of electric vehicles so bad?

If there is no battery, more than 100 million electric bicycles in my country will not be able to start, and more than 1 billion mobile phones cannot be used normally. With the rapid development of the automobile, ship and communication industries, the battery as a cost-effective power source has also developed rapidly. However, because batteries contain heavy metal lead, any careless processing and recycling will pollute the environment. The pollution caused by batteries is not in the use of battery cars, but in the processing and recycling. The nationwide recycling battery network has not been established for a long time, and 80% of the recycling share goes to self-employed. How to find a point that not only guarantees the extraction of recycled lead for processing, reduces the consumption of resources, but also minimizes the pollution to the environment, and maintains the balance of the coordinated development of the economy and the environment has become a question for all those who care about environmental protection. ●A staggering number of hundreds of millions of batteries are being recycled and dismantled in an electric car shop in Huadu, the electric car owner Mr. Liu explained to reporters that his electric car was bought in early 2014 and the battery was replaced just a month ago. When asked about the whereabouts of the old battery, he said that he sold it to a peddler collecting scrap for 30 yuan. The reporter has not seen the recycling business of used batteries in many electric vehicle sales points. They can only trade in old batteries. Each battery can be up to 10 to 20 yuan, while some waste collection stations recycle used batteries at a price ranging from 20 to 40 yuan. Has advantages in price. According to relevant data, 80% of the recycling share of waste batteries goes to self-employed. Electric bicycles are considered a low-carbon, environmentally friendly way of travel. However, most electric bicycles currently use lead-acid batteries. If they are not properly resolved after they are scrapped, they will cause immeasurable pollution to the environment. According to figures released by the my country Bicycle Association, the number of electric bicycles in my country in 2012 has reached 140 million. At the same time, it is not only electric bicycles that use lead-acid batteries, but also a growing family of cars. This means that in about two years, there will be hundreds of millions of battery packs facing recycling and dismantling. ●The current situation is worrying. The local method of smelting lead has become a natural enemy of the environment. The reporter has investigated small lead smelting plants three times and witnessed the whole process of smelting lead in 11 small workshops. A brief summary of the small lead smelting process is six ones, namely, a hammer to smash the plastic casing of scrap lead-acid batteries, a willow basket to collect scrap lead plates, a large pot of smelting lead slag, and an iron mill. Add fuel for smelting, a blower to heat the smelted regenerated lead, and a set of iron models to cast the smelted lead water. The reporter's investigation found that a large number of individual recycled lead smelting sites concealed in the underground were all after the batteries were disassembled, the lead-containing acid solution was poured everywhere, and a crucible was set up in the open to start smelting lead. This is what many local lead smelters do. The operation process. These small workshops not only have no formal industrial and commercial and tax registration, but also have a low level of processing, and they have no ability to control pollution. Smelting waste and waste gas can be solved at will, becoming a new source of pollution. Environmental behavior has been repeatedly prohibited and has become a regulatory dead end that has caused a headache for regulatory authorities.
