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...

Todorokite-type manganese oxide nanowires as an intercalation cathode for Li-ion and Na-ion batteries

Vibration Durability Testing of Nickel Manganese Cobalt Oxide (NMC) Lithium-Ion 18,650 Battery Cells

Electric vehicle (EV) manufacturers are employing cylindrical format cells in the construction of the vehicles’ battery systems. There is evidence to suggest that both the academic and industrial communities have evaluated cell degradation due to vibration and other forms of mechanical loading. The primary motivation is often the need to satisfy the minimum requirements for safety certification...

Visualization of lithium-ion transport and phase evolution within and between manganese oxide nanorods

Multiple lithium-ion transport pathways and local phase changes upon lithiation in silver hollandite are revealed via in situ microscopy including electron diffraction, imaging and spectroscopy, coupled with density functional theory and phase field calculations. We report unexpected inter-nanorod lithium-ion transport, where the reaction fronts and kinetics are maintained within the neighbouri...
