Are lithium-ion batteries green and pollution-free?

Is lithium-ion battery green in the end? Environmental protection? New energy vehicle is a popular green synonym, and its heart is the mainstream lithium-ion battery. So, is industry green? In Jeju Island, South Korea, one of the world's largest ecological demonstration projects has been completed, including a lithium-ion battery factory. Nie said that this $1 billion-plus project involves a South Korean supplier that supplies batteries for electric vehicles in Detroit. According to reports, lithium-ion batteries must be able to store more than 85% of the electricity. After long-term use, the storage capacity will decrease. Once it drops below 85%, it cannot be used. But the lithium-ion battery removed from the car will not be wasted and will not cause damage to the environment. In the demonstration project, the eliminated lithium-ion batteries will be used as free electrical equipment for villas and offices to store green electricity generated by wind and solar energy. Lithium-ion battery products themselves are not polluted. Unlike traditional lead-acid batteries, lead-acid batteries will be polluted by heavy metals, and the special nature of recycling makes them more environmentally friendly. Nie Tianxin said. It is reported that the green engineering of lithium-ion battery plants has been demonstrated and applied in many foreign countries. At present, my country is also preparing to formulate the next planning method for the automotive lithium-ion battery industry, in order to tap the inherent green value of the industry. Will there be pollution in the production of lithium-ion batteries? Hu Liqing, an overseas returnee who has been engaged in the research and development of new energy batteries in Canada and the United States, pointed out that the environmental problems caused by the production of lithium-ion batteries are far lower than traditional batteries. As long as the chemical solvents volatilized during the production process are fully concentrated and recovered, pollution can be prevented. In this regard, foreign countries have environmental standards to restrict, and domestic standards have also formulated strict access standards. According to Hu Liqing, lithium iron phosphate battery companies have factories in many developed countries in Europe and America. For example, the famous American A123 lithium-ion battery company has production bases in Missouri, Germany and South Korea, and received technical subsidies from the US government at the beginning of the company's establishment. In addition, the lithium-ion battery industry in Japan and South Korea is also rising rapidly. Multinational giants such as Japan’s NEC, South Korea’s LG and South Korea’s Samsung have cooperated with domestic automakers to develop a new generation of lithium-ion battery products in their respective countries. A BYD official said that the factory is located in Pingshan District, Shenzhen and meets European environmental standards. Daimler itself has strict restrictions on battery suppliers, not only in terms of product quality and safety, but also in terms of factory environmental indicators. The person in charge said. According to reports, battery production has experienced five generations of lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium cobalt acid batteries, lithium manganese acid batteries and lithium iron-phosphorus batteries. Among them, the fourth-generation batteries all use heavy metals, and there is a risk of heavy metal pollution in the production, use and recycling process. Lithium iron phosphate is the fifth-generation battery, free of heavy metals and rare metals, non-toxic (SGS certification), non-polluting, in line with European RoHS regulations, and is a green battery. No matter in production and use, there is no pollution. Therefore, this kind of battery was included in the 863 National High-tech Development Plan during the fifteenth period, and became a key national support and encouragement project statement: Some pictures and contents of articles published on this site are from the Internet.
