Economically viable electric vehicle lithium-ion battery recycling is increasingly needed; however routes to profitability are still unclear. We present a comprehensive, holistic techno-economic model as a framework to directly compare recycling locations and processes, providing a key tool for recycling cost optimization in an international battery recycling economy. We show that recycling can be economically viable, with cost/profit ranging from (-21.43 - +21.91) $·kWh but strongly depends on transport distances, wages, pack design and recycling method. Comparing commercial battery packs, the Tesla Model S emerges as the most profitable, having low disassembly costs and high revenues for its cobalt. In-country recycling is suggested, to lower emissions and transportation costs and secure the materials supply chain. Our model thus enables identification of strategies for recycling profitability.
经济上可行的电动汽车锂离子电池回收需求日益增长;然而,盈利途径仍不明确。我们提出了一个全面、整体的技术经济模型,作为直接比较回收地点和工艺的框架,为国际电池回收经济中的回收成本优化提供了关键工具。我们表明,回收在经济上是可行的,成本/利润范围为(-21.43 - +21.91)美元·千瓦时,但强烈依赖于运输距离、工资、电池组设计和回收方法。比较商用电池组,特斯拉Model S成为最具盈利性的,其拆解成本低,钴的收入高。建议在国内进行回收,以降低排放和运输成本,并确保材料供应链。因此,我们的模型能够确定回收盈利的策略。
