Solutions for large-scale and comprehensive utilization of retired power batteries

'With the rapid development of new energy vehicles, power lithium batteries are ushering in the peak of retirement. In 2020, the sales of new energy vehicles will exceed 1.3 million, and the retired power lithium batteries will be 26.49GWh, nearly 237,800 tons, and have a market space of 13.1 billion. In 2022, 184 It will reach 35.4 billion yuan by 2025, and the market space is huge.' On December 16-18, [Lee Yuanheng’s name] 2020 Senior Engineer Lithium Electric Vehicle Annual Conference was grandly opened at the Hyatt Hotel in Shenzhen Airport , Nearly 1,000 senior executives from the power lithium battery industry chain gathered to discuss the new blueprint for the industry in the next ten years. On the morning of the 18th, a special session on new applications and new batteries was held by [Hymus Laser Title]. Xiong Ping, Director of Echelon Utilization of Hengchuang Rui Energy, gave a keynote speech entitled 'Solutions for Large-scale Comprehensive Utilization of Decommissioned Power Batteries'. And make the above judgment. Xiong Pingping said that the market space is huge, but the current waste power battery recycling market is still in the early stages of development. Driven by profits, retired power lithium-ion batteries will also flow into the gray market, and small workshops that are not qualified for disposal are dismantling and recycling lithium-ion. During the battery process, various safety accidents such as environmental protection and fire will be caused. The improper use and handling of decommissioned power lithium-ion batteries can easily cause leakage, electric shock and cause safety accidents. At the same time, nickel, cobalt, manganese, heavy metals, organic solvents, and fluorides can cause environmental pollution. Therefore, how to safely and effectively recycle power lithium batteries has become an urgent problem facing the company. According to Xiong Ping, the comprehensive utilization of power lithium batteries includes cascade utilization and regeneration. And encourage the priority to use after the cascade recycling; give priority to the entire group of cascade utilization, the latter monomer cascade utilization. At the same time, information about retired batteries and comprehensive utilization is entered into the new energy recycling management platform (tracing code system). The large-scale comprehensive utilization of decommissioned power batteries is inseparable from the four key technologies of regeneration technology, online repair technology, non-destructive testing technology, and big data analysis technology. Among them, the regeneration technology is the automatic environmental protection crushing, the extraction of valuable metal materials, and the material storage; the online repair technology is the active balance, which adjusts the voltage and capacity of the battery pack (group) online; the non-destructive testing technology is the development of the whole package ( Group) on-line testing equipment, online detection of retired power lithium battery packs (groups), and health status assessment; while big data analysis is to analyze the historical data of retired power lithium battery packs (groups), establish mathematical models, and predict remaining life. As a national high-tech company for the recycling and comprehensive utilization of decommissioned power lithium batteries, Hengchuang Ruineng has two production bases in Shenzhen, Huizhou and Jiangmen. Among them, the Huizhou base has a decommissioned battery storage center, an echelon utilization center, and an automated lithium-ion battery processing workshop, with a full processing output of 50,000 tons. Jiangmen base lithium-ion battery echelon utilization and intelligent dismantling 50,000 tons/year, and lithium-ion battery material purification 50,000 tons/year. Xiong Ping pointed out that Hengchuang Ruineng has established close cooperation with Geely Automobile, Wanxiang 123, GAC New Energy, Xinwangda, Yiwei Lithium Energy, BYD and other new energy vehicle factories and power lithium battery manufacturers. In March 2020, it cooperated with Shenzhen Bus Group and the battery proprietor my country Putian Group to dismantle and recycle the first batch of decommissioned power lithium batteries. At present, Hengchuang Ruineng has recycled more than 10,000 tons of power lithium batteries and related wastes, and has been certified in the market and commercial feasibility with technologies and methods. Finally, Xiong Ping revealed that in order to meet the rapidly rising demand for the disposal of decommissioned batteries for new energy vehicles, Hengchuang Ruineng plans to expand its channels nationwide in five years, and at the same time build 6 power lithium battery recycling (or temporary storage and transfer) bases: Beijing-Tianjin-Hebei Construction North China (Baoding) base and the Yangtze River Delta to build the East China (Nanjing) base.
