This innovative technology focuses on efficiently recovering lithium ions (Li+) from aquatic environments and used electric vehicle (EV) Li-ion batteries. By utilizing specially designed materials such as Crown ethers (CEs) and Cyclodextrins (CDs), as well as their modified forms, the technology enables the creation of micro/nanoparticles, super porous cryogels, and fibers for enhanced Li+ ion adsorption. These materials possess unique properties that allow them to selectively capture Li+ ions from various sources. By harnessing these advanced materials, the process of Li+ ion recovery becomes more effective and environmentally friendly. The technology offers a range of solutions including tailored micro/nanoparticles, cryogels, and fibers that can be combined for even greater efficiency. This breakthrough has significant implications for the clean energy market and sustainable battery production.
