Customer ServiceDespite some methods achieving recovery rates of up to ninety-nine percent, the global recovery rate of lithium from lithium-ion batteries (LIBs) is currently below 1%. This is due to the high energy consumption for lithium extraction and the high operation cost associated with the processes .
Recent advancements in the electrochemical recovery of lithium-ion batteries are divided into two main approaches: electrochemical leaching and electrodeposition [21, 22, 23]. For electrochemical leaching, the electric current is applied to the battery materials, thus achieving the dissolution of metal ions in the solution.
While these technologies offer hope, the current amount of lithium recovered from dead batteries is insufficient due to the niche nature of the market. However, as the demand for lithium continues to grow, companies may increasingly turn to recycling to meet the needs of the expanding electric vehicle market.
The study of lithium battery recycling involves exploring various mechanisms of deactivation and degradation of lithium battery materials, as well as analyzing the role of the molten salt recycling method in the pre-treatment, separation, and extraction of valuable metals, and the direct/indirect regeneration of cathode materials.
Recently, direct recovery for spent LIBs makes the closed-loop circulation of electrode materials due to the direct use of degraded active materials as raw materials to produce fresh active materials. Thus its underlying sustainability of using less chemical agents and energy cost has increasingly acttracted attentions from battery community.
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.
