In recent years, lithium-ion batteries have been widely used in electric vehicles and electronic products. As the lithium-ion battery market continues to grow, the number of discarded lithium batteries has increased annually, making the development of recycling and regeneration technologies increasingly crucial. Lithium-ion batteries contain critical metals such as lithium (Li), manganese (Mn), nickel (Ni), and cobalt (Co). These raw materials face uncertainties such as uneven geographical distribution, unstable supply, and resource scarcity, making lithium-ion battery recycling and recovery a key technology with both economic value and environmental benefits. This article introduces the classification of lithium-ion batteries, compares current and innovative technologies for the recycling and recovery of critical metals, and explores potential future directions for recycling and recovery advancements.
