The Ministry of Industry and Information Technology said that at present, the number of waste power batteries is still very small, and the waste power batteries recycled by enterprises mainly come from the defective products produced in the process of research and development and manufacture of battery manufacturers. And the "Ten cities and thousands of vehicles Project" to promote decommissioned batteries for vehicles. The recycling technology of waste power battery is mainly hydrometallurgy and physical restoration, and the comprehensive recovery rate of nickel, cobalt, manganese and other metal elements in hydrometallurgy can reach 98%. In addition, under the condition of pyro-smelting, the comprehensive recovery of nickel and rare earths should not be less than 97%.
On the whole, the recycling technology is relatively mature, but the key technologies and equipment such as efficient extraction of valuable metals need to be upgraded, and the level of pollution prevention and treatment of waste power batteries needs to be improved. The regeneration and utilization of lithium iron phosphate battery is faced with the problem of poor economy.
Next, the Ministry of Industry and Information Technology will make full use of the existing scrapped cars, electronics and electrical appliances disassembly and non-ferrous metallurgy and other industrial foundation, overall layout of power battery recycling enterprises, to promote the sustainable development of the industry.
-ladder utilization has formed a pilot effect.
For vehicle power batteries with capacity falling below 80%, cascade utilization may be a more efficient treatment. However, due to the limitations of the technical level of domestic battery pack, there is no perfect means to detect the battery margin and the number of charge and discharge, the cost of disassembly and sorting is high, coupled with the cost of transportation and assembly, the benefit of cascade utilization of domestic lithium iron phosphate battery is not high.
On the 18th, the Ministry of Industry and Information Technology said on its public account platform that it was actively carrying out a pilot project for the recovery and utilization of power batteries for new energy vehicles. We will promote enterprises such as automobile manufacturing, battery production and comprehensive utilization to carry out step-by-step utilization tests in the fields of power preparation and energy storage, and explore new business models.
