Recovery of Cobalt and Lithium by Carbothermic and Hydrogen Reduction of Spent Lithium-Ion Battery

Over the last decade, the demand for Li-ion batteries has significantly increased, particularly due to the growing interest in electric vehicles. As a result, there is an increasing demand for raw materials in these batteries. To address this demand and manage the environmental impact of spent batteries, recycling is necessary. The thesis proposed two alternatives of recycling by implementing high temperature processes. Firstly, carbothermic reduction using secondary carbon materials such as graphite anode was implemented. Secondly, another reducing agent of hydrogen gas was applied which emphasized zero-carbon emission process.
