Leaching Process for the Recovery of Valuable Metals from Spent Lithium- Nickel-cobalt-manganese-oxide-based Lithium-ion Batteries
This study focused on the leaching process for the recycling of Li, Ni, Co, and Mn from the LiNixCoyMnzO2 (NCM) cathodes of spent lithium-ion batteries (LIBs). Eh–pH diagrams were used to analyze suitable leaching conditions. Operating variables, such as the concentration of H2SO4 (0.5–2.5 M), concentration of H2O2 (0–1 vol%), temperature (10–50 °C), stirring speed (400–800 rpm), and solid/liqu...
متن کاملRecovery of cobalt and lithium from spent lithium ion batteries using organic citric acid as leachant.
In this work, a hydrometallurgical process based on leaching is applied to recover cobalt and lithium from spent lithium ion batteries (LIBs). Citric acid and hydrogen peroxide are introduced as leaching reagents and the leaching of cobalt and lithium with a solution containing C(6)H(8)O(7) x H(2)O is investigated. When both C(6)H(8)O(7) x H(2)O and H(2)O(2) are used an effective recovery of Li...
متن کاملRecovery of cobalt sulfate from spent lithium ion batteries by reductive leaching and solvent extraction with Cyanex-272
Cobalt sulfate was recovered from crushed and screened prismatic type spent lithium ion batteries (LIBs) containing 5~20 % Co, 5~7 % Li, 5~10 % Ni, 15% organic chemicals, and 7% plastics together with Cu, Al, Fe, and Mn. Cobalt was reductively leached from the -16 mesh fraction in 1 h by stirring with 2 M H2SO4 and 6 vol% H2O2, at 60 C and 300 rpm using a solid/liquid ratio of 100 g/L to give a...

an approach to recycle precious metals of cathode materials from spent lithium cobalt oxide batteries by using organic citric acid and hydrogen peroxide has been studied in this paper. the effects of molar ratio, solid-liquid ratio, reaction time and temperature on leaching efficiency of cobalt were investigated respectively. meanwhile the leaching kinetics equation of cobalt was established, a...
متن کاملLithium Ion Batteries—Development of Advanced Electrical Equivalent Circuit Models for Nickel Manganese Cobalt Lithium-Ion
In this paper, advanced equivalent circuit models (ECMs) were developed to model large format and high energy nickel manganese cobalt (NMC) lithium-ion 20 Ah battery cells. Different temperatures conditions, cell characterization test (Normal and Advanced Tests), ECM topologies (1st and 2nd Order Thévenin model), state of charge (SoC) estimation techniques (Coulomb counting and extended Kalman ...
