| Abstract Scope |
Green and sustainable recycling of lithium-ion batteries is an area that requires global attention due to the rapid growth in the electric vehicle (EV) market. In this work, a holistic study is presented to develop a closed-loop Li and Co metal recovery and separation process using oxalic acid from LiCoO<sub>2</sub> electrode material. A novel oxalic acid regeneration process using ion-exchange resins is used to recover oxalate, reduce waste production, and lower the overall cost of the process. The experimental results are supported by thermodynamic and kinetic modeling studies, which provides application to other aqueous metal chemistries that can be applied to recycling new battery types such as NMC cathodes. This presentation will describe the experimental and modeling results for the process and the application of oxalate chemistry to other energy-efficient extractions such as Al from bauxite and Ti from ilmenite. |
