Electrochemical Approach for Lithium Recovery from Spent Lithium-Ion Batteries: Opportunities and Challenges Along with the increasing demand for portable electronics and electrical vehicles, the rapid proliferation of lithium-ion batteries (LIBs) is consuming the primary lithium source fast and generates a huge amount of spent LIBs.
Regarding the secondary resources, i.e., recycling the spent LIBs, the recycling process consists of dismantling the LIBs, in some cases the sepn. of the cathode and anode materials, leaching of shredded material, and sepn. and recovery of metals.
Because the main failure mechanism of spent LIBs is the loss of lithium, which leads to changes in the valence state of other elements and the collapse of the overall structure, electrochemical lithium replenishment has become the core feature of this technology. Various inorganic lithium salts are currently the lithium sources in the electrolyte.
First, the reasons for the performance degradation of LIBs during use are comprehensively analyzed, and the necessity of recycling retired batteries is analyzed from the perspectives of ecology and safety, sustainable development, economy, energy conservation and emission reduction.
We examine various lithium recovery methods, including conventional techniques such as hydrometallurgy, pyrometallurgy, and direct physical recycling, as well as emerging technologies like mechanochemistry, ion pumping, and bioleaching while emphasizing the need for sustainable practices to address environmental challenges.
