- Abstract
- New precursors as a Li adsorbent, Li_1.6(MnM)_1.6O₄(M=Cu, Ni, Co, Fe), were synthesized by hydrothermal method and their physicochemical properties were discussed. XRD and HRTEM results revealed that the original spinel structure was stabilized by cobalt-doping while Cu-, Ni- and Fe-doping led to structural changes. Such a structural stabilization by Cobalt-doping was maintained after lithium leaching by acid treatment. Li absorption efficiency from seawater was significantly enhanced by using the Cobalt-doped spinel manganese oxide, Li_1.6[MnCo]_1.6O₄, compared to the commercially available Li_1.33Mn_1.67O₄; the adsorbed amount of Li from 1g-adsorbent was 35 and 16 mg by Li_1.6[MnCo]_1.6O₄, and Li_1.33Mn_1.67O₄, respectively.
