Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
A solid electrolyte constituted by a macromolecular material of ionic conduction, characterized by the fact that it is formed of cross-linked polymers or oligomers containing heteroatoms in the monomer unit or in side chains as well as cross-linkable functions and containing one or more ionizable salts and having a glass transition temperature as low as possible.
Claim 2
Dependent Claim
56 words
A solid electrolyte constituted by a macromolecular material of ionic conduction, characterized by the fact that it is formed of cross-linked polymers or oligomers containing heteroatoms in the monomer unit or in side chains as well as cross-linkable functions and containing one or more ionizable salts and having a glass transition temperature as low as possible.
Claim 3
Dependent Claim
23 words
A solid electrolyte according to claim 1, characterized by the fact that the heteroatoms are selected from among nitrogen, oxygen, sulfur and phosphorus.
Claim 4
Dependent Claim
35 words
A solid electrolyte according to claim 2, characterized by the fact that the ratio of the number of carbon atoms to the number of heteroatoms in the polymer or oligomer is between 1 and 12.
Claim 5
Dependent Claim
27 words
A solid electrolyte according to any of claims 1 to 3, characterized by the fact that it is formed from a mixture of several polymers or oligomers.
Claim 6
Dependent Claim
32 words
A solid electrolyte according to claim 1, characterized by the fact that the ionizable salts are salts of alkali metals, selected from among the salts of lithium, sodium, potassium, rubidium or cesium.

Claim 8
Dependent Claim
39 words
A solid electrolyte according to either of claims 5 and 6, characterized by the fact that the ratio of the number of metal cations to the number of heteroatoms in the polymer or oligomer is between 1 and 30%.
Claim 9
Dependent Claim
44 words
A solid electrolyte according to any of claims 1, 2, 3, 5 and 6, characterized by the fact that the polymers or oligomers are sequenced or grafted statistical copolymers or sequenced or grafted polycondensates derived from cyclic ethers, formaldehyde, acetaldehyde, aziridines or ethylene diamine.
Claim 10
Dependent Claim
22 words
A solid electrolyte according to claim 8, characterized by the fact that the polymer is a propylene-polyoxide/ethylene-polyoxide copolymer or an oxyethylated polyamine.
