Lithium Extraction from Seawater through Pulsed Electrochemical Intercalation.
'Seawater contains 5,000 times more Li [Lithium] than the combination of ore and brine-based resources. However, the chemically similar Na [Sodium] is four orders of magnitude more concentrated than Li, which poses a significant challenge in Li extraction selectivity.'
