96kwh energy storage lithium solar battery.Develop management for recycling and recycling of scrap batteries

During this year's two sessions, Zhang Tianren submitted the "Recommendations on Strengthening the Recycling and Utilization of Scrapped Power Lithium Batteries to Ensure the Security of National Resource Strategies." He said that there are two main destinations for retired new energy vehicle lithium batteries. The first is echelon utilization, which is used for power backup in telecommunications base stations; the second is recycling, which involves dismantling and refining the heavy metals for reuse. "From a full life cycle perspective, batteries that are used in secondary applications also need to be recycled after they are finally scrapped." On the one hand, there will be a large number of scrapped lithium batteries. On the other hand, my country's lithium resources are heavily dependent on imports. Data show that my country's dependence on foreign lithium mines exceeds 85%; "Chinese demand" has also driven the price of battery-grade lithium carbonate to skyrocket, rising from less than 50,000 yuan/ton at the beginning of 2015 to 180,000 yuan/ton at the end of 2017, an increase of three times This greatly increases the procurement costs of my country's lithium-ion battery manufacturing companies and poses challenges to resource security. Zhang Tianren said that improper handling or random discarding of scrap lithium batteries will cause great harm to the ecological environment. For example, heavy metal elements such as cobalt and nickel in the positive electrode material, organic matter in the electrolyte, and carbon materials in the negative electrode will cause pollution to water and soil. In severe cases, it may be difficult to recover for decades. In this regard, Zhang Tianren suggested that relevant departments should speed up the development of management, technology and evaluation standards for the recycling and reuse of scrap batteries, such as battery remaining testing standards; speed up the study of fiscal and tax incentives, industrial funds, points management and other incentive policies, and explore power batteries Market-oriented models such as residual value trading promote the recycling of power lithium batteries. "Currently, the recycling technology is not yet mature, and dismantling is mainly done manually, and the cost remains high." Zhang Tianren said that in view of the weak links in recycling, joint research between industry, academia and research should be organized to break through key common technologies and effectively reduce production costs; encourage Lithium battery manufacturing companies with production capacity and technological advantages should build regeneration and recycling projects and strengthen planning to avoid the "rush" of regeneration and recycling projects, leading to overcapacity and waste of resources. my country's lithium-ion battery industry has been in a state of "insufficient high-quality production capacity." For example, in the field of power batteries, power battery companies outside the top ten have a total market demand of about 13%, but they account for about 55% of the industry's total production capacity. , most of which belongs to low-end production capacity, and its capacity utilization rate is only about 10%, which has lowered the overall capacity utilization index of the industry. Although the "Interim Measures for the Management of Lithium-ion Battery Industry Standard Announcements" issued this time exclude "power batteries for new energy vehicles" from the scope of applicable enterprises, in 2016, the proportion of power batteries in lithium-ion battery production was 45.08%. Yin Chengliang, deputy dean of Shanghai Jiao Tong University's Automotive Engineering Research Institute, believes that following technological changes such as lead-acid and nickel metal hydride, lithium-ion batteries are currently booming, but my country's nearly 200 power battery companies are too large in scale and are in great need of mergers and acquisitions. and integration. Performance reports for the first three quarters of 2018 show that my country's small and medium-sized battery companies suffered substantial losses. Although the new document does not include power batteries used in new energy vehicles, industry insiders believe that this will definitely have an impact on the development and regulation of the vehicle power battery industry. "For the lithium-ion battery industry, the new document clearly regulates issues such as safety and intelligent manufacturing, which will help lithium battery companies develop healthily from disorderly competition to orderly competition." Sun Wei said that due to the regulations The content is more specific and operable, and the concepts of intelligent and green manufacturing are clearer. This also clarifies the development direction of the enterprise and provides "rules to follow" in the development process.
