Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
An ionic/electronic composite conductor comprising a continuous, coherent electronic conducting material selected from the group consisting of polyacetylene, polyphenylene, polyphenyl diphenyl vinylene and a substituted polyacetylene intimately mixed with a continuous ionic conducting material which is a mixture of a complex of an ionic salt and a polymeric solvating agent, such that the ionic conducting material has an increased melting point over its normal melting point.
Claim 2
Dependent Claim
66 words
An ionic/electronic composite conductor comprising a continuous, coherent electronic conducting material selected from the group consisting of polyacetylene, polyphenylene, polyphenyl diphenyl vinylene and a substituted polyacetylene intimately mixed with a continuous ionic conducting material which is a mixture of a complex of an ionic salt and a polymeric solvating agent, such that the ionic conducting material has an increased melting point over its normal melting point.
Claim 3
Dependent Claim
12 words
The conductor of claim 1 wherein the conductor is a coherent film.
Claim 4
Dependent Claim
14 words
The conductor of claim 1 wherein the polymeric solvating agent is a polyalkylene oxide.
Claim 5
Dependent Claim
23 words
The conductor of claim 3 wherein the electronic conducting material is polyacetylene prepared by heating a polymer of 7,8-bis-(trifluoromethyl) tricyclo-[4,2,3,0 2 .5 ]-deca-3,7,9-triene.
Claim 6
Dependent Claim
38 words
An energy storage cell comprising two electrodes, at least one of which is an ionic/electronic conductor as defined in claim 1, and a solid electrolyte therebetween, the solid electrolyte being an ionic conductor but not an electronic conductor.
Claim 7
Dependent Claim
21 words
The energy storage cell of claim 5 wherein the two electrodes are each an ionic/electronic conductor as defined in claim 1.
Claim 8
Dependent Claim
39 words

Claim 9
Dependent Claim
15 words
The conductor of claim 1, wherein the electronic conducting material is a conducting hydrocarbon polymer.
