Selective lithium recovery from brine using LNCM/Ag battery system |
| 초록 |
LiNi1/3Co1/3Mn1/3O2 (LNCM) was investigated for its feasibility in selective electrochemical lithium recovery in brine solution. The recovery system consists of LNCM and Ag as Li+ intercalating electrode and a chloride capturing electrode respectively. LNCM was first oxidized (Li extracted) to facilitate its Li preference during capture phase (discharging). The captured ions were then released (charging) to a separate cell containing a recovery solution. Repetitive Li capture-release process and cyclic voltammetry showed high selectivity and stability of the electrode in the presence of other competing cations (Na+, K+, Ca2+, Mg2+). Overall, the results demonstrate the ability of the electrochemical system to selectively recover Li+ from aqueous sources with comparable energy consumption.
