The volume of spent LIBs is growing exponentially and could be a rich source of valuable materials including Li, Co, Mn, Ni, Al, Cu, and Fe. Therefore, these valuable materials can be recycled from spent LIBs and recirculated in the supply chain that will uplift the sustainable development of the Li-ion battery industry.
With the rising demand and production of lithium-ion batteries, their recycling is gaining increased priority. Since the cathode active material of lithium-ion batteries are rich in valuable metals, recycling spent lithium-ion batteries are of great significance for abating resource scarcity and environmental pollution.
Besides, transition metal oxides and mesocarbon microbeads synthesised from LIBs are used in adsorption and photocatalysis applications (Natarajan and Aravindan, 2018a). The recovered materials have the potential of applications as raw materials for battery manufacturing.
Acidic, alkali, and other chemical solvents through heating and stirring are usually used to leach out the spent lithium-ion batteries to extract the valuable metal elements in the hydrometallurgical recovery process , , .
The reserves of virgin materials such as cobalt, nickel and lithium required for LIB manufacture is limited, restricted to a few nations, and is not expected to keep up with the growing demand for storage in electronic devices and EVs in the coming decades. Critical metals such as Li, Co, and Ni are especially vulnerable to supply chain issues.
The leaching method can effectively recover the valuable elements Li, Ni, Co, and Mn in the form of ions from the cathode materials of spent lithium-ion batteries into solution, and the subsequent recovery of the metals can be carried out through methods including chemical precipitation and solvent extraction.
Real-World Implementations Across Diverse Sectors
Methods in recycling battery materials can be classified into three types: (1) direct recycling, (2) pyrometallurgy, and (3) hydrometallurgy [5,6,7]. Direct recycling recovers useful battery components through mostly physical recycling processes with minimum chemical treatments [6, 7]. This method has a short recovery route and a high recovery ...
