METHODS OF PURIFYING LITHIUM SALTS |
摘要 |
Provided are methods of purification of an organic lithium salt comprising the steps of: (a) dissolving an impure organic lithium salt in a solution comprising an organic complexing solvent; (b) crystallizing from said solution a solid solvate complex comprising said lithium salt and said organic complexing solvent; (c) separating said solid solvate complex from said solution; (d) dissociating said solid solvate complex to yield: (i) said lithium salt in a solid form, and, (ii) a volatile composition comprising said organic complexing solvent; and, (e) removing said volatile composition to yield said lithium salt in a solid form of purity greater than the purity of said impure lithium salt. The present invention also pertains to electrolytes for electric current producing cells comprising such purified lithium salts. |
