摘要

Recycling spent lithium-ion batteries (LIBs) is necessary for environmental protection and the reuse of valuable resources. Previous studies have used the LCA method to evaluate the environmental and energy performance of single spent LIB recycling. However, lacking research can provide an overall view of the spent LIBs recycling. This study uses a systematic meta-analysis method to quantitatively analyze different independent research results. We draw the following conclusions. (1) The global warming potential (GWP) and cumulative energy demand (CED) of recycling 1 kg spent LIBs are 0.158-44.59 kg CO2-eq and 3.3-154.4 MJ, respectively. (2) There are significant differences in GWP and CED during the life cycle of LIBs recycling with different battery types, shapes, recycling processes, and electric sources. Compared with NCM batteries, the GWP and CED of recycled LFP batteries are higher. The combined hydro-pyrometallurgical process performs the best for GWP and CED, while the pyrometallurgy is the worst. The GWP of LIBs recycled by Chinese electricity is the highest, and the CED of LIBs recycled by American electricity is the highest. (3) Among the influencing factors, cascade utilization contributes the most.
