ppm) with a nominal Li/Mg selectivity >45 million. ppm) and an abundance of interfering ions (i.e., 13000 ppm of sodium, magnesium, calcium, and potassium ions, among others). Instead, the lithium concentration and the ratio of lithium to other multivalent ions, such as Mg 2+ and Ca 2+ , are the key factors to consider.

IBC demonstrates highly selective high-yield direct lithium extraction from Salar de Maricunga brine

Green Car Congress

The Pilot Plant has undergone validation testing and begun Phase One operation, the results from which demonstrate highly selective, high-yield direct lithium extraction from brine and high water efficiency. Concentrations of key elements in the Salar de Maricunga brine are: Li (0.767 g/L), Mg (5.37 Complete recycling of process water.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. A typical Li-air battery discharges at 2.5-2.7
