Environmentally Friendly Process for Battery Recycling
An environmentally friendly deep eutectic solvent was used to extract valuable elements from the metal oxides commonly used as cathodes in lithium-ion batteries. The solvent, made of commodity products choline chloride and ethylene glycol, extracted more than 90 percent of cobalt from powdered compounds and a smaller but …
Recovery of valuable metals from spent lithium-ion batteries using microbial agents …
Among the various types of recycling methods, bleaching is cost-effective, environmentally friendly, simple in operation and less energy intensive (Golmohammadzadeh et al., 2022; Mokarian et al., 2022).
Deep eutectic solvents for cathode recycling of Li-ion batteries
The ever-increasing applications for Li-ion batteries in markets call for environmentally friendly and energy-efficient recycling technologies. Here the authors report using a deep eutectic ...
Environmentally Friendly Lithium-Ion Battery Recycling Process
However, viable recycling solutions for these batteries are largely confined to either burning them or chemically dissolving shredded batteries. ORNL researchers Lu Yu and Yaocai Bai examine vials that contain a chemical solution that causes the cobalt and lithium to separate from a spent battery, followed by a second …
