| titleOfInvention | Preparation method of lithium bis-oxalate borate and lithium tetrafluoroborate |
| abstract | The invention relates to a preparation method of an electrolyte lithium salt used in the lithium ion battery industry, in particular to a preparation method of lithium bis-oxalate borate and lithium tetrafluoroborate. The preparation methods of the lithium bis-oxalate borate and lithium tetrafluoroborate include: (1) in an inert atmosphere, dissolving lithium difluorooxalate borate to form a solution; and (2) at a temperature of 0-105° C., 101-150kpa An ionic coordination catalyst is added to the solution under pressure to form a reaction product comprising lithium bisoxalatoborate and lithium tetrafluoroborate. The method of the invention has the advantages of fast reaction rate, simple reaction conditions, convenient operation and high yield; it can reduce the cost of raw materials, reduce material consumption and waste generation, improve the utilization rate of raw materials, product yield and purity, and make Purification of the product is easier. |
