Abstract

Salts of N-containing heterocyclic anions as components in electrolytes Novel uses of salts of N-containing heterocyclic anions, novel salts of fluorinated N-containing heterocyclic anions and method for producing the same are described. Preferred compounds have a pyrimidone or a pyrazole ring structure bearing a trifluoromethyl group and a metal counter ion.

First claim

1 . An electrolyte comprising a compound of general formula I

or any tautomer thereof;
wherein A is a linking group comprising 3 or 4 annular atoms independently selected from C, N, O or S; and wherein M n⊕ is a cation and n is 1, 2, 3 or 4.

2 . The electrolyte of claim 1 , wherein the compound of general formula I is a compound of general formula II

or any tautomer thereof,
wherein A is a linking group comprising 3 or 4 annular atoms independently selected from C, N, O or S;
wherein X and Y are independently selected from the group consisting of H, alkyl, F and Cl.

3 . The electrolyte of claim 1 , wherein M is a metal.

4 . The electrolyte of claim 1 , wherein A is —C(O)N═CH—CH═ and the compound is

or any tautomer thereof.

5 . The electrolyte of claim 1 , wherein A is —N═CH—CH═ and the compound is

or any tautomer thereof.

6 . A lithium ion battery, a sodium ion battery, a supercapacitor or hybrid supercapacitor, or an organic photovoltaic device comprising the electrolyte according to claim 1 .

7 . A superconductor comprising the electrolyte according to claim 1 .

8 . A compound of general formula II

or any tautomer thereof,
wherein A is a linking group comprising 3 or 4 annular atoms independently selected from C, N, O or S;
wherein X and Y are independently selected from the group consisting of H, alkyl, F and Cl; and
wherein M n⊕ is a metal cation and n is 1, 2, 3 or 4.

9 . The compound of claim 8 wherein A is —C(O)N═CH—CH═ and the compound is

or any tautomer thereof.

10 . The compound of claim 8 wherein A is —N═CH—CH═ and the compound is

or any tautomer thereof.

11 . The compound of claim 8 , wherein —CFXY is —CF 3 , —CHF 2 , or —CClF 2 .

12 . The compound of claim 11 wherein —CFXY is —CF 3 .

13 . The compound of claim 8 , wherein M is Li, Na or Zn.

14 . An electrolyte comprising the compound of claim 8 and at least one other component.

15 . A lithium ion battery, a sodium ion battery, a zinc ion battery, a supercapacitor or hybrid supercapacitor, or an organic photovoltaic device comprising the electrolyte of claim 14 .

16 . The electrolyte of claim 1 , further comprising at least one other component

17 . The electrolyte of claim 16 , wherein the at least one other component is selected from the group consisting of a conductive salt, a solvent, and a solvent additive.

18 . The electrolyte of claim 14 , wherein the at least one other component is selected from the group consisting of a conductive salt, a solvent, and a solvent additive.

19 . The compound of claim 12 , wherein M is Li.
