The increasing prevalence of lithium-ion batteries in electric vehicles, consumer electronics, and renewable energy systems has led to a pressing demand for efficient recycling methods. This review delves into the essential elements of lithium-ion batteries and examines the primary recycling techniques: pyrometallurgy, hydrometallurgy, and direct recycling. Every approach presents unique advantages and obstacles regarding expenses, energy consumption, efficiency of recovery, and ecological effects. Pyrometallurgy is frequently employed, yet it requires elevated temperatures and generates emissions. Hydrometallurgy provides enhanced material recovery, yet it involves a greater use of chemicals and intricate processes. Direct recycling, currently being explored, demonstrates promise in maintaining material value. Even with advancements in technology, obstacles like inconsistent regulations, inadequate collection systems, and limited public awareness continue to persist. Tackling these challenges is essential for establishing a sustainable and circular battery economy. This paper seeks to provide a comprehensive overview to aid in future research and policy formulation regarding battery waste management.
