摘要

生命周期评估(LCA)量化了产品从摇篮到坟墓的整个生命周期对环境的影响。它对产品生命周期每个阶段的能源使用、材料流动和排放进行评估。本报告探讨了在美国电动汽车(EV)市场指数级增长的背景下,与电动汽车(EV)电池激增相关的挑战和潜在解决方案。报告重点关注锂离子电池(LIB)的处置和回收对环境和经济的影响。随着过去十年间数百万辆电动汽车的售出,这项研究强调了高效回收方法的必要性,以减轻电池生产和处置对环境造成的破坏。利用生命周期评估(LCA)和生命周期成本评估(LCCA),本研究采用 SimaPro V7 和 GREET V2 等软件工具,比较了新电池和回收电池的排放量和成本。研究结果表明,回收电池对环境的影响大大低于用新材料制造新电池,而且在经济上也是可行的。这项研究还强调了为即将涌入的废旧电动车电池做好准备的重要性,并为今后优化电动车电池处置和回收利用的研究提供了建议。

Sustainable Management of Rechargeable Batteries Used in Electric Vehicles
A Life Cycle Assessment (LCA) quantifies the environmental impacts during the life of a product from cradle to grave. It evaluates energy use, material flow, and emissions at each stage of life. This report addresses the challenges and potential solutions related to the surge in electric vehicle (EV) batteries in the United States amidst the EV market’s exponential growth. It focuses on the environmental and economic implications of disposal as well as the recycling of lithium-ion batteries (LIBs). With millions of EVs sold in the past decade, this research highlights the necessity of efficient recycling methods to mitigate environmental damage from battery production and disposal. Utilizing a Life Cycle Assessment (LCA) and Life Cycle Cost Assessment (LCCA), this research compares emissions and costs between new and recycled batteries by employing software tools such as SimaPro V7 and GREET V2. The findings indicate that recycling batteries produces a significantly lower environmental impact than manufacturing new units from new materials and is economically viable as well. This research also emphasizes the importance of preparing for the upcoming influx of used EV batteries and provides suggestions for future research to optimize the disposal and recycling of EV batteries.
