Ecofriendly Recycling of Lithium-Ion Batteries
以环保方式回收锂离子电池
Duesenfeld combines mechanical, thermodynamic and hydrometallurgical processes in a patented process. The process achieves the highest material recovery rates with low energy consumption. This is made possible by a process control with low temperatures, in which toxic hydrogen fluoride are not produced. Exhaust gas scrubbing is not necessary in the mechanical processing step. The fluorides are removed in a targeted and safe manner in hydrometallurgy.
Duesenfeld 在专利工艺中结合了机械、热力学和湿法冶金工艺。该工艺以较低的能耗实现了最高的材料回收率。这得益于低温工艺控制,在低温条件下不会产生有毒的氟化氢。在机械加工步骤中无需进行废气洗涤。在湿法冶金过程中,氟化物被有针对性地安全去除。
Duesenfeld operates the only recycling process that, in addition to the usual metals, also supplies graphite, electrolytes and lithium for material recycling. Material recycling does not mean a declaration as a building material, e.g. for road construction, but all metals are recovered with high recovery rates in the form of high-quality secondary raw materials up to battery quality. The production of secondary raw materials with the Duesenfeld recycling process saves 8.1 tons of CO2 per ton of recycled batteries compared to the primary extraction of the raw materials3)4). Compared to conventional melting processes, the Duesenfeld process saves 4.8 tons of CO2 per ton of recycled batteries3)5), compared to mechanical processes with exhaust gas scrubbing, the saving is 1 ton of CO2 per ton of recycled battery3).
杜森菲尔德拥有唯一的回收工艺,除了常见的金属外,还提供石墨、电解质和锂,用于材料回收。材料回收并不意味着将其作为建筑材料(如用于道路建设),而是以高质量二次原材料的形式,以高回收率回收所有金属,直至电池质量。采用杜森费尔德回收工艺生产二次原材料,与一次提取原材料 3) 4) 相比,每吨回收电池可节省8.1吨二氧化碳 2 。与传统熔化工艺相比,杜森菲尔德工艺每吨回收电池 3) 5) 可节约 4.8 吨二氧化碳 2 ,与带废气洗涤的机械工艺相比,每吨回收电池 3) 可节约 1 吨二氧化碳 2 。
Electric mobility is Climate Friendly only with Duesenfeld Recycling
只有杜森费尔德回收技术才能实现电动汽车的气候友好性
CO2 savings from electric mobility to slow down global warming must not be nullified by inappropriate recycling of the batteries. With the environmentally friendly process from Duesenfeld, no CO2 is produced during mechanical recycling, no toxic filter materials have to be deposited.
电动汽车为减缓全球变暖而减少的二氧化碳排放量不能因为电池回收不当而抵消。采用杜森菲尔德的环保工艺,在机械回收过程中不会产生二氧化碳 2 ,也不会沉积有毒的过滤材料。
The Duesenfeld process achieves a more than twice as high material recovery rate for lithium-ion batteries as conventional recycling methods through mechanical processing. Supplemented by hydrometallurgical processes, almost complete recycling is possible. End-of-life batteries are usually classified as hazardous goods and transported in battery transport containers. The electrolyte is separated from the other substances by mechanical processing with modular recycling systems on site, the resulting products no longer require special hazardous goods transport containers. These intermediates are transported in standard containers, which makes it possible to transport 7 times the amount per truck. This reduction in the transport of dangerous goods saves a large part of the total recycling costs of the batteries.
Duesenfeld 工艺通过机械加工实现的锂离子电池材料回收率是传统回收方法的两倍多。辅以湿法冶金工艺,几乎可以实现完全回收。报废电池通常被归类为危险品,用电池运输容器运输。通过现场的模块化回收系统进行机械加工,将电解液与其他物质分离,得到的产品不再需要特殊的危险品运输容器。这些中间产品用标准集装箱运输,每辆卡车的运输量是原来的 7 倍。危险品运输量的减少为电池回收总成本节省了很大一部分。
Our focus is on recycling the batteries as completely as possible. Duesenfeld achieves a recycling rate of 72% in mechanical recycling, with the processing of the black mass in Duesenfeld hydrometallurgy, the material recycling rate increases to 91%. Only the separator film and the high boiler portion of the electrolyte are not recovered at the moment. Duesenfeld thus goes far beyond the current requirements of the EU Battery Directive 2006/66/EC.
我们的重点是尽可能彻底地回收电池。Duesenfeld 在机械回收方面的回收率达到 72%,在 Duesenfeld 湿法冶金中对黑块进行处理后,材料回收率提高到 91%。目前只有分离膜和电解液中的高锅炉部分没有回收。因此,Duesenfeld 远远超出了目前欧盟电池指令 2006/66/EC 的要求。
