Abstract

The rapid rise of electric vehicles has made lithium a vital resource. In addition to obtaining lithium from nature, used lithium-ion batteries (LIBs) have become a supplementary lithium resource. The energy consumption and greenhouse gas (GHG) emissions of this technology need to be figured out for a comprehensive evaluation. In this article, we calculate and compare the energy consumption and GHG emissions of obtaining lithium from used LIBs, brines, and solid ores by several typical commercial-scale projects as examples. The results show that the energy consumption and GHG emissions of recovering lithium from used LIBs are 2.879 kgce and 8.232 kg CO₂ equivalent, respectively. Although the energy consumption and GHG emissions of obtaining lithium from spodumene are close to the former, the LIBs recycling technology is more competitive because many by-products with high utilization value are produced. Therefore, the promotion of this technology should be promoted in the future.
