Patent number: 11779886Abstract: The presently disclosed concepts relate to improved techniques for alkali metal extraction (and in particular lithium), using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions.
