| LiPO2F2, an electrolyte salt additive for batteries, is manufactured by the reaction of POF3, PF5 or mixtures thereof, with Li3PO4 forming a reaction mixture comprising LiPO2F2. When POF3 is applied, the reaction mixture which contains essentially only LiPO2F2 is preferably extracted from the reaction mixture with a solvent which also is applicable as solvent for lithium ion batteries. If PF5 is applied, then, depending on the molar ratio of PF5 and Li3PO4, the reaction mixture also contains LiF and/or LiPF6. To isolate pure LiPO2F2 from LiF, the reaction mixture containing essentially only LiPO2F2 and LiF may for example, be extracted with dimethoxyethane, acetone, dimethyl carbonate or propylene carbonate. To isolate pure LiPO2F2 from LiPF6, the reaction mixture containing essentially only these constituents is preferably extracted with a solvent which also is applicable as solvent for the LiPF6 in lithium ion batteries to dissolve and remove LiPF6. | ||||||

| A composition is provided as a salt having the formula MBF3X where M is an alkali metal cation and X is the halide fluoride, bromide or iodide. A lithium salt has several characteristics making the composition well suited for inclusion within a lithium-ion battery. A process for forming an alkali metal trifluorohaloborate salt includes the preparation of a boron trifluoride etherate in an organic solvent. An alkali metal halide salt where the halide is chloride, bromide or iodide is suspended in the solution and reacted with boron trifluoride etherate to form an alkali metal trifluorohaloborate. The alkali metal trifluorohaloborate so produced is collected as a solid from the solution. The process is simple and yields alkali metal trifluorohaloborate of sufficient purity to be used directly in battery applications. | ||||||

| 210 | Process for producing lithium concentrate from brine or seawater | US10274956 | 2002-10-22 | US06764584B2 | 2004-07-20 | I-Long Chang; Yu-Lin Jiang; Jer-Yuan Shiu; Jiunn-Ren Lin |
| Two concentration techniques, adsorption and electrodialysis, are combined to enrich lithium ions in brine from a level of several ppm to about 1.5%. At beginning brine is subjected to an adsorption, so that Li content is increased to 1200-1500 ppm, followed by two stages of electrodialysis in series to increase Li ions to about 1.5%. Li depleted solution from the second stage of electrodialysis having a Li content of 1200-1500 ppm is recycled to the first stage of electrodialysis as a feed. Li depleted water from the first stage of electrodialysis is subjected to a residue recovery electrodialysis to form a Li enriched solution of 1200-1500 ppm, which is also recycled to the first stage of electrodialysis as a feed. Li depleted solution from the residue recovery electrodialysis is recycled as a feed of the adsorption, so as to sufficiently recover Li ions from brine. | ||||||

| The present invention provides a process for generating acid-free lithium salt solutions for lithium and lithium ion batteries and for preparing high purity lithium salts. The invention comprises removing acid species from lithium salt solutions such as lithium hexafluorophosphate solutions using weak base resins. The process does not require the addition of a base such as ammonia which when added to the electrolytic solution generally must be removed from the final product. Once the lithium salt has been treated by the weak base resin, the substantially acid-free lithium salt solution may be recovered from the weak base resin to provide a solution which may be used as an electrolytic solution or which may be used to prepare high purity lithium salts. | ||||||

| Lithiated manganese oxides are synthesized using a novel two stage process. Using appropriate starting materials, lithiation is accomplished via low temperature ion exchange in aqueous warm salt solution. A drying stage follows which completes the synthesis. Materials suitable for use as cathodes in lithium ion rechargeable batteries have been prepared in this way. Other solid solution transition metal materials might also be prepared using a similar low temperature ion exchange process. | ||||||

| Lithium-containing brines containing mono and multivalent cations, especially magnesium, and anions are treated by electrodialysis to effect separation of a lithium concentrate low in multivalent cations from which lithium can be recovered as chloride, sulfate, or carbonate. Brine containing 0.03 to 15 g/L Li and a ratio of Mg:Li as high as 60:1 is subjected to one or more electrodialysis steps. The preferred cationic and anionic membranes are those that are strongly acidic and have sulphonic acid radical and trimethylamine derivatives, respectively, as active groups at 3 to 4 milligram equivalent per gram of dry resin and have a matrix of styrene divinyl benzene copolymer on a pvc base. Electrodialysis is carried out at a pH below 7 under turbulent conditions. The number of electrodialysis steps depends on the permselectivity of the membranes, the Mg:Li ratio in the feed and that in the concentrate, the latter being maintained at 5:1 or less. The chloride concentration in the electrode compartments is maintained at less than 3 g/L. In multi-step electrodialysis, a portion of the magnesium may be removed in an intermediate stage by the addition of lime, the lithium in the resulting solution being further concentrated by electrodialysis. | ||||||
