Are lithium-ion batteries environmentally friendly?

Lithium-ion batteries are environmentally friendly because they are made of materials that do not contain polluting metals, and there are no pollutants in the production process. And because of its high energy ratio, good circulation effect, no memory effect and other advantages. The development has been widely used. It can be said that lithium batteries have bred a revolution in energy applications. In recent years, the applications of lithium-ion batteries include consumer electronics, power lithium batteries and energy storage batteries. Consumer electronics are the mainstream market, while the energy storage market technology is not yet mature. Currently, the future home of lithium lies in power lithium batteries. Due to its environmental protection characteristics, electric bicycles have received a lot of support from the government. As the first choice for power lithium batteries, bans on super cars have been promulgated throughout the country. This contributes to the development of lithium-ion batteries. Lithium-ion batteries will beat lead-acid batteries in the power market for small and medium-sized systems. The speed at which lithium-ion batteries replace lead-acid batteries depends on the rate at which the cost of lithium-ion batteries declines. This process is expected to be completed in the next ten years. These markets are not sensitive to technology, but sensitive to cost. Following electric bicycles, electric vehicles and energy storage, a new round of lithium demand blowout will be set off. my country’s support for electric vehicles will continue to rise. The reasons include getting rid of oil and improving the environment. Compared with electricity applications, the consumption of lithium is a secondary issue. The rise of power lithium batteries has truly opened up people's infinite imagination space for lithium-ion batteries, which have become ideal products for electric vehicle applications. The key to the development of electric vehicles is to rely on technological progress to reduce costs and improve the safety and economy of electric vehicles. At present, the performance breakthrough of Tesla's electric vehicles has achieved good results and brought dawn to the industry. Further promote the classification and recycling of waste batteries (1) Environmental management of waste batteries The 'Technical Policy for Pollution Prevention and Control of Waste Batteries' stipulates that the recycling of waste primary batteries shall be carried out carefully by the recycling unit. At present, in the absence of effective recycling under technical and economic conditions, the centralized collection of used primary batteries that meet the national requirements for low or no mercury is discouraged. At present, the primary batteries (dry batteries) sold on the market have reached the low or no mercury requirements stipulated by the state, and they are allowed to be disposed of together with household garbage after being discarded. In recent years, environmental protection departments have conducted research on the pollution characteristics of waste batteries through public welfare projects. The research results show that when waste batteries are processing domestic garbage, they will increase the difficulty of disposal or add additional environmental risks (such as the enrichment of zinc fly ash from incineration, which increases the difficulty of disposal of fly ash). Therefore, we believe that the recycling of used primary batteries is of positive significance to environmental protection. We are working with the National Development and Reform Commission, the Ministry of Commerce, the Ministry of Industry and Information Technology and other departments to study and formulate a waste primary battery recycling policy, and promptly promote the pilot recycling of waste primary batteries. At the same time, it is organizing the revision of the 'Technical Policy for Waste Battery Pollution Prevention and Control(2) Environmental management of waste batteriesAccording to the prevention and control policy of technical waste battery pollution, the focus of waste battery collection is cadmium nickel batteries, nickel hydroxide batteries, lithium ion batteries, lead-acid batteries and other discarded rechargeable batteries, silver oxide Batteries and other discarded key batteries (high mercury content). Regarding lead-acid batteries, in 2013, with the approval of the State Council, the Ministry of Industry and Information Technology, the Ministry of Commerce, the National Development and Reform Commission, the Ministry of Finance and other departments issued opinions to promote the standardized development of lead-acid batteries and the regenerated lead industry (hereinafter referred to as the opinions) . Regarding the recycling and utilization of used lead-acid batteries, the 'Opinions' clearly requires the establishment of a standardized and orderly recycling system to achieve standardized production, orderly recycling and reasonable recycling of lead-acid batteries. By 2015, the comprehensive utilization rate of waste lead-acid battery recycling will reach more than 90%, and the lead recycling ratio will reach more than 50%, which has promoted the formation of a national lead resource recycling system. At the same time, further regulate the recycling of used lead-acid batteries by individual vendors, encourage production companies to organize the recycling of used lead-acid batteries through retail outlets, and support production companies, sales companies, professional recycling companies and lead recycling companies to jointly build a recycling network. At the same time, the state has preferential tax policies for the recycling of waste lead-acid batteries. Since 2010, the National Development and Reform Commission and the Ministry of Finance have organized the construction of urban mineral resources demonstration bases, and arranged special funds for the development of circular economy to support the construction of demonstration bases. Among them, Jieshou in Anhui, Pizhou in Jiangsu and Jitianli in Shanxi are important demonstration bases for recycling lead. At the same time, the state implements a 50% value-added tax refund policy for companies that use waste lead-acid batteries to produce recycled lead.
