Novel LiAlO Material for Scalable and Facile Lithium Recovery Using Electrochemical Ion Pumping.

In this study, α-LiAlO was investigated for the first time as a Li-capturing positive electrode material to recover Li from aqueous Li resources. The material was synthesized using hydrothermal synthesis and air annealing, which is a low-cost and low-energy fabrication process. The physical characterization showed that the material formed an α-LiAlO phase, and electrochemical activation revealed the presence of AlO* as a Li deficient form that can intercalate Li.
