Method for synthesizing ionic complex, electrolytic solution for non-aqueous electrolyte battery, non-aqueous electrolyte battery and ionic complex

摘要

To provide a material suitable for a nonaqueous electrolyte battery having high-temperature durability. An ionic complex of the present invention is represented by any of the following formulae (1) to (3). For example, in the formula (1), A is a metal ion, a proton, or an onium ion; M is any of groups 13 to 15 elements. R 1 represents a hydrocarbon group which may have a ring, a heteroatom, or a halogen atom, the hydrocarbon group having 1 to 10 carbon atoms, or -N(R 2 )-. R 2 at this time represents hydrogen, alkali metal, a hydrocarbon group which may have a ring, a heteroatom, or a halogen atom, the hydrocarbon group having 1 to 10 carbon atoms. R 2 can also have a branched chain or a ring structure when the number of carbon atoms is 3 or more. Y is carbon or sulfur. When Y is carbon, r is 1. When Y is sulfur, r is 1 or 2. a is 1 or 2, o is 2 or 4, n is 1 or 2, p is 0 or 1, q is 1 or 2, and r is 0, 1 or 2. When p is 0, a direct bond is formed between S and Y.
