Ultra-fast and stable extraction of Li metal from seawater†
Abstract
Ultra-dense (99.2%) and ultra-stable Li7La3Zr2O12 were synthesized via a spark plasma sintering (SPS) technique, which were applied as solid-state electrolytes in Li metal extraction from seawater. 198 μg cm−2 h−1 of extraction efficiency and 1.0%–3.7% of power comsumption showed their promising potential for Li metal extraction.
