METHOD FOR PRODUCING SOLUTION OF LITHIUM DIFLUOROBIS(OXALATO)PHOSPHATE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a solution of lithium difluorobis(oxalato)phosphate that is to be an effective additive for improving performance of nonaqueous electrolyte battery and has small amounts of chlorine compounds and free acids. <P>SOLUTION: The method for producing a solution of lithium difluorobis(oxalato)phosphate includes mixing lithium hexafluorophosphate with oxalic acid in the molar ratio of 1:1.90-1:2.10 in a nonaqueous solvent and reacting the mixture with silicon tetrachloride in the molar ratio of silicon tetrachloride to lithium hexafluorophosphate of 1:0.95-1:1.10. <P>COPYRIGHT: (C)2010,JPO&INPIT |
