Salt of bicyclic aromatic anions for Li-ion batteries

摘要

A method for obtaining salts of bicyclic imidazole compounds (V) having general structural formulae in which A represents a monovalent cation, X represents independently a carbon atom, an oxygen atom, a sulphur atom or a nitrogen atom. Also, the associated production method and to the use thereof, in particular as an electrolyte component for batteries.

1. A process for the preparation of a salt of a bicyclic imidazole compound of general formula (Va), wherein general formula (Va) is represented by the general formula below: wherein A represents a monovalent alkali metal cation and X independently represents a carbon atom, a phosphorus atom or a nitrogen atom, wherein an imidazole compound of formula (IVa): is reacted with a base AZ, wherein A is the same monovalent cation as in general formula (Va) and Z is a hydride, hydroxide or carbonate anion.
