Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
Ionically conductive material composed of a salt in solution in a solvent, characterized by the fact that the salt is represented by one of the following formulas: ##STR4## in which: M is an alkali metal, alkaline earth metal, transition metal, or rare earth metal, RF and R'F, which are identical or different, each represents a perhalogenated, preferably perfluorinated group having from 1 to 12 carbon atoms, R is hydrogen or an alkyl group having from 1 to 30 carbon atoms, QF is a divalent perfluorinated group having from 2 to 6 carbon atoms.
Claim 2
Dependent Claim
93 words
Ionically conductive material composed of a salt in solution in a solvent, characterized by the fact that the salt is represented by one of the following formulas: ##STR4## in which: M is an alkali metal, alkaline earth metal, transition metal, or rare earth metal, RF and R'F, which are identical or different, each represents a perhalogenated, preferably perfluorinated group having from 1 to 12 carbon atoms, R is hydrogen or an alkyl group having from 1 to 30 carbon atoms, QF is a divalent perfluorinated group having from 2 to 6 carbon atoms.
Claim 3
Dependent Claim
16 words
Material pursuant to claim 1, characterized by the fact that the solvent is an aprotic liquid.
Claim 4
Dependent Claim
16 words
Material pursuant to claim 1, characterized by the fact that the solvent is a macromolecular material.
Claim 5
Dependent Claim
21 words
Material pursuant to claim 3, characterized by the fact that the macromolecular material is a homopolymer or copolymer of ethylene oxide.
Claim 6
Dependent Claim
16 words
Material pursuant to claim 3, characterized by the fact that the macromolecular material is a polyphosphazene.
Claim 7
Dependent Claim
46 words
Material pursuant to claim 2, characterized by the fact that the solvent is a sulfone represented by the formula: ##STR5## in which R 1 , R 2 , R 3 , and R 4 are alkyl or oxaalkyl groups having from 1 to 10 carbon atoms.
