Examining The Life Cycle Analysis Of Electric Vehicle Batteries: A Review

International Sustainable Resource Recovery Strategies Towards Zero Waste (FULLRECO4US) Conference, İstanbul, Türkiye, 13 - 15 Eylül 2023, ss.46

Life cycle assessment (LCA) is a methodology used to evaluate the environmental impacts associated with

the entire life cycle of a product or system. Over the course of electric vehicle (EV) adoption, there has

been a progressive increase in the number of LCA studies focusing on EV batteries. However, there is a

need for further LCA research of advanced battery technologies and their environmental impacts. This

study provides an in-depth review of the life cycle assessment on electric vehicle batteries. Relevant

papers on LCA studies for EV batteries published in journals from 2019 to 2023 were reviewed. The review

explores various aspects of LCA studies conducted on EV batteries, including their manufacturing, use,

and end-of-life stages. It examines the methodologies, data sources, and impact categories considered in

these assessments. The review highlights the key findings and trends identified across different studies.

The study reveals that the environmental impact of EV batteries is primarily influenced by the extraction

and processing of raw materials, energy consumption during manufacturing, and end-of-life disposal or

recycling processes. The review demonstrates the necessity of greater efforts to address data limitations

and system boundaries and to enable meaningful comparisons across individual LCA studies. It also

recognizes the significance of future research in areas such as developing sustainable battery materials,

manufacturing process improvements, and recycling technology advancements. In conclusion, this study

provides valuable insights into the LCA of EV batteries, shedding light on the environmental implications

of their life cycle.
