Lithiothermic Reduced TiO2 for Efficient Adsorption of Li-ion

Graphical Developing an effective material to recover lithium from salt-lake brines or used batteries is highly demanded. We report a reduced TiO 2 nanomaterial with numerous lithium vacancies by lithiothermic reaction, exhibiting a high Li-ion adsorption capacity of 26 mg/g from solution. Considering the growing lithium demand and the potential shortage of lithium resource, developing an effective material to recover lithium from salt-lake brines or used batteries is highly needed. Here, we report a reduced TiO 2 nanomaterial (LiTiO 2 ) with numerous lithium vacancies by lithiothermic reaction, which exhibited high adsorption capacity of 26 mg/g from lithium-ion solution.
