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.
