Today, the utilization of lithium-ion batteries (LIBs) has significantly increased as an energy storage technology. In recent years, the high demand for lithium for LIB has resulted in a significant increase in the consumption of lithium-containing materials. It is anticipated that the reduction of lithium due to the limited reserves of lithium will be one of the major challenges in the future. The primary component of the lithium-ion battery industry is lithium, which is extracted from natural minerals and saline water. However, the extraction of lithium from natural minerals and saline water is a complex process that requires a significant amount of energy. Conversely, the quantity of batteries that are approaching the end of their lifespan is unavoidably increasing at an alarming rate. In order to address the obstacles that the lithium battery supply chain encounters, it is imperative that a variety of recycling technologies and methodologies be further developed. This article concentrates on technologies that can recycle lithium compounds from LIB through distinct processes and procedures. These stages are further divided into two pre-treatment phases and a lithium extraction stage. The lithium extraction stage is further divided into three primary methods: pyrometallurgy, hydrometallurgy, Direct. This review article quantitatively compares and analyzes the processes, advantages, disadvantages, efficiency, price, environmental contamination, and degree of commercialization of each recycling method. This review can offer a suitable perspective to enhance this path.
