| abstract |
The invention concerns novel lithium fluorophosphates of general formula Li+[PFa(CHbFc(CF3)d)e]- (I) in which: a designates 1, 2, 3, 4 or 5; b designates 0 or 1, c designates 0, 1, 2 or 3; d designates 0, 1, 2 or 3; and e designates 1, 2, 3 or 4, provided that the total of a + e equals 6, the total of b + c + d equals 3, and b and c do not simultaneously designate 0, and provided that the ligands (CH¿b?Fc(CF3)d) can be different. The invention further concerns a process for preparing these compounds, their use in electrolytes, and lithium batteries produced with these electrolytes. |
