Wuhan team develops new electrochemical cell for efficient, pollution-free extraction of lithium from salt lake brines

Green Car Congress

Researchers at Wuhan University in China have developed a new electrochemical cell, PANI/Li x Mn 2 O 4 , for selective recovery of Li + ions from brine water with high impurity cations (K + , Na + , Mg 2+ , etc). This method avoids using additional chemicals, offering a high efficiency, pollution?free —Zhao et al.
