salt and a sodium salt or a potassium salt. Claims 1 and 27 are
illustrative:
1. A method for preparing a lithium salt of formula LiX,
comprising:
reacting lithium salt selected from lithium chloride,
lithium sulfate, and combinations thereof with NaX or KX in an
aqueous solution;
adding an organic solvent to the aqueous solution to produce
a semiaqueous solution; and
removing the precipitated solids from the semiaqueous
solution to obtain a LiX solution.
27. A method for preparing a lithium salt of formula LiX,
comprising:
reacting lithium salt selected from lithium chloride,
lithium sulfate, and combinations thereof with NaX or KX in a
semiaqueous solution comprising water and an organic solvent to
produce LiX, the amount of water in the semiaqueous solution
being between about 1 and about 4 moles per mole of LiX; and
removing the precipitated solids from the solution to obtain
a LiX solution.
