The increasing production and usage of lithium-ion batteries (LIBs) have resulted in significant environmental concerns due to the generation of cathode scraps containing critical metals. This study aims to optimize a closed-loop recycling process for LiNi1/3Co1/3Mn1/3O2 from cathode scraps and investigate the kinetics of metal leaching. We employed a hydrometallurgical method utilizing trichloroacetic acid (TCA) as the leaching agent and examined the influence of various parameters, including temperature and the concentration of oxidizing agents, on leaching efficiency. The leaching rates of nickel, cobalt, and manganese were quantitatively analyzed, revealing that optimal conditions could elevate their recovery rates significantly, with hydrogen peroxide and different sodium salts playing critical roles as reducing agents. The results indicated that a balance of chemical concentration and temperature is essential to enhance the leaching kinetics and overall efficiency of the process. Through this optimization, we sought not only to recover valuable metals from LIB waste but to propose a sustainable and environmentally protective method of handling battery scraps. Overall, our findings contribute to the advancement of recycling technologies for reducing toxic waste and recovering essential resources from spent lithium-ion batteries.
