Environmental life cycle assessment of recycling technologies for ternary lithium-ion batteries

Abstract

To combat climate change, the transition to electrification has become a major trend in the transportation sector. However, the increasing growth in electric vehicles leads to a serious challenge to the waste management of retired power batteries. With the emergence of various recycling technologies, there is widespread concern about which ones are environmentally friendly. Consequently, a general life cycle assessment model is developed, which covers the whole process of production, using and recycling of ternary lithium-ion battery. China is taken as a case here, which is the largest electric vehicle market in the world. With the overall comparison of 5 different recycling technologies, the key links and main contributing factors to reduce the environmental impacts are further identified. Eventually, relevant decision-making supports for managing the end-of-life ternary lithium-ion power batteries are provided. Show more
