Abstract: The increasing demand for electric vehicles and related lithium-ion batteries leads to the implementation of battery production in Europe. Recently, legal obligations, high material prices, and supply risk of battery materials induced OEMs to set up recycling facilities or cooperate with battery recyclers. Different network structures emerged in this process. However, it remains unclear how the network structures influence the performance in the short-term. Therefore, a novel multi-stage, multi-product, multi-period production planning approach for closed-loop supply chains of lithium-ion batteries is developed. The model considers a spatial distribution of collection, recycling, repurposing, and production. Furthermore, the facilities of the OEM and suppliers a considered simultaneously. The collection is further divided into cost-free take-back of spent batteries and purchase of additional batteries. This approach enables the stakeholders of the closed-loop supply chain to counteract material shortages or price fluctuations. Subsequently, the effects of different network structures are analyzed based on a case study for closed-loop supply chains of lithium-ion batteries in Europe. The results indicate that centralized and decentralized networks can achieve adequate performance. In this context, the transformation toward closed-loop supply chains is beneficial for all network structures. Furthermore, circular factories outperform all network structures in the short term due to the in-house production of batteries and short transportation distances.
摘要:電動車及相關鋰離子電池需求的不斷增長導致電池生產在歐洲實施。近年來,法律義務、高材料價格以及電池材料的供應風險促使整車廠建立回收設施或與電池回收商合作。在這個過程中出現了不同的網路結構。然而,目前尚不清楚網路結構如何影響短期效能。因此,開發了一種新穎的鋰離子電池閉環供應鏈多階段、多產品、多週期生產規劃方法。該模型考慮了收集、回收、再利用和生產的空間分佈。此外,同時考慮 OEM 和供應商的設施。收集又分為免費回收廢棄電池和購買額外電池。這種方法使閉環供應鏈的利害關係人能夠應對材料短缺或價格波動。隨後,以歐洲鋰離子電池閉環供應鏈為例,分析了不同網狀結構的影響。結果顯示集中式和分散式網路都可以實現足夠的效能。在此背景下,轉型為閉環供應鏈對所有網路結構都有好處。 此外,由於電池的內部生產和運輸距離短,循環工廠在短期內優於所有網路結構。
