Lithium-ion batteries (LIBs) are an essential part for electric vehicles (EVs) and have experienced rapid growth with the strong demand for EVs. Concerns over the sustainable supply of EV-LIBs have been voiced, but only a few studies have investigated the international trade in EV-LIBs, which has a significant impact on EV production in the complicated and volatile international trade environment. To fill this gap, this study investigates the international EV-LIB trade from a dynamic perspective. First, the dynamic structural evolution of the EV-LIB trade from 2012 to 2019 is explored from three perspectives, i.e., backbone structure, geospatial characteristics and trade communities, by constructing a weighted and directed network. Second, the hidden systemic risks in the international EV-LIB trade are revealed by the proposed trade network risk transmission (TNRT) model in two supply shortage scenarios. The results show a heterogeneous structure in the backbone network, and the trade barycenter is transitioning from Asia to Europe. In addition, a “robust-yet-fragile” characterization is revealed in the global EV-LIB trade network, and the hidden risks in leading EV-LIB exporter nodes and trade edges are uncovered. The findings will support authorities seeking effective strategies to manage the EV-LIB trade and build a more resilient trade system.

国际汽车锂离子电池贸易中的贸易结构和风险转移

锂离子电池(LIB)是电动汽车(EV)的重要组成部分,并且随着电动汽车的强劲需求而经历了快速的增长。人们对EV-LIB的可持续供应表示了担忧,但只有很少的研究调查了EV-LIB的国际贸易,这在复杂多变的国际贸易环境中对EV生产产生了重大影响。为了填补这一空白,本研究从动态角度研究了国际EV-LIB贸易。首先,通过建立加权和定向网络,从骨干结构,地理空间特征和贸易共同体三个角度探讨了2012- 2019年EV-LIB贸易的动态结构演变。第二,在两种供不应求的情况下,拟议的贸易网络​​风险传递(TNRT)模型揭示了国际EV-LIB贸易中隐藏的系统性风险。结果表明,骨干网结构是异构的,贸易重心正在从亚洲过渡到欧洲。此外,全球EV-LIB贸易网络还揭示了“稳健而脆弱”的特征,并且未发现领先的EV-LIB出口商节点和贸易优势中的隐患。调查结果将支持当局寻求有效的策略来管理EV-LIB贸易并建立更具弹性的贸易体系。在全球EV-LIB贸易网络中揭示了“稳健而脆弱”的特征,并且发现了领先的EV-LIB出口商节点和贸易优势中的隐患。调查结果将支持当局寻求有效的策略来管理EV-LIB贸易并建立更具弹性的贸易体系。在全球EV-LIB贸易网络中揭示了“稳健而脆弱”的特征,并且发现了领先的EV-LIB出口商节点和贸易优势中的隐患。调查结果将支持当局寻求有效的策略来管理EV-LIB贸易并建立更具弹性的贸易体系。
