Direct lithium extraction from spent batteries for environment friendly lithium recycling – Insta News Hub

Lately, the analysis findings of Professor Xie’s group (Huazhong College of Science and Technology) were printed in Science Bulletin. This research proposed a easy, environment friendly, and low-energy chemical leaching technique, using a lithium extraction answer composed of polycyclic fragrant hydrocarbon reagents and ether solvents to immediately extract lively lithium from retired batteries.

Researchers screened a sequence of reagents with totally different redox potentials and solubilities primarily based on the molecular structural traits and studied their binding mechanisms with lithium.

Furthermore, by systematically analyzing the connection between the redox potential and extraction effectivity, coupled with theoretical calculation, the optimum reagent was chosen. The environment friendly restoration of lively lithium from spent batteries was achieved by the optimization of solvent and course of parameters.

Notably, the recovered lively lithium can function a vital lithium supply. It may be immediately employed to react with iron phosphate by spontaneous redox reactions, thereby making ready high-performance lithium iron phosphate supplies.

Physicochemical characterization and electrochemical efficiency exams confirmed the prevalence of the supplies ready by this technique. As well as, the recycling of lithium from business batteries enabled the large-scale preparation of lithium iron phosphate cathode supplies, demonstrating their sensible utility prospects.

Importantly, lithium extraction options function inside a closed-loop system, minimizing the opportunity of environmental air pollution. As well as, the lithium extraction reagents may be recycled for reuse. In contrast with different recycling applied sciences, this system has good financial advantages and sensible prospects, and it’s anticipated to advertise the sustainable growth of lithium-ion batteries.
