摘要:

随着电动汽车产业的蓬勃发展,锂离子电池作为电动汽车的核心部件,其环境影响和可持续性研究得到了广泛关注。在双碳背景下,基于全生命周期的锂离子电池碳足迹评价已经成为解决锂电池可持续发展的关键问题,不同研究由于锂离子电池材料、回收技术等差异,研究结果差异较大。本文总结了锂离子电池全生命周期碳足迹的研究进展,对锂离子电池“从摇篮到坟墓”(全生命周期)、“从大门到大门”(生产阶段)、“从摇篮到摇篮”(回收阶段)三个方面进行了总结分析,重点关注了生产阶段与回收阶段,分析发现生产阶段磷酸铁锂电池的碳足迹较低,回收阶段中湿法回收镍钴锰酸锂电池的效益最优,新技术的研发、绿色能源的开发与使用能有效减少锂离子电池全生命周期中生产、使用、回收等阶段的碳足迹。最后,对影响锂离子电池碳足迹的多个因素进行了展望,为锂离子电池的可持续发展与双碳目标的实现提供了依据。

Abstract:

With the vigorous development of the electric vehicle industry, lithium-ion batteries (LIBs), as the core components of electric vehicles, have received extensive attention based on their environmental impact and sustainability. Under the background of dual-carbon policy, the carbon footprint evaluation of LIBs based on the full life cycle has become a key problem to solve the sustainable development of LIBs battery. Different studies have different research results due to differences in LIBs materials and recycling technologies. This paper summarizes the research progress of the full life cycle carbon footprint of LIBs, with the perspective "from the cradle to the grave" (full life cycle), "from the gate to the gate" (production stage), and "from the cradle to the cradle" (recovery stage), focusing on the production stage and the recovery stage. It is found that the carbon footprint of lithium iron phosphate batteries in the production stage is low. The benefit of hydrometallurgical recovery of lithium nickel cobalt manganese oxide battery is the best in the recovery stage. It is also found that the research and development of new technologies and the development and use of green energy can effectively reduce the carbon footprint of LIBs in the production, use and recycling stages of the full life cycle. Finally, this study looks forward to the future of multiple factors affecting the carbon footprint of LIBs and provides a basis for the sustainable development of LIBs and the realization of dual-carbon goals.

Key words: dual-carbon strategy, electric vehicle, lithium-ion battery, life cycle assessment, carbon footprint evaluation
