Abstract

A metal-oxygen battery can provide improved energy storage and transportation applications due to high gravimetric energies, and such a metal-oxygen battery can include a polyolefin including a plurality of functional groups such as sulfamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups.

First claim

What is claimed:

1. A composition comprising a polyolefin including a plurality of functional groups in a backbone of the polyolefin, directly bonded to a backbone of the polyolefin via an N or O, or a C4-C6 alkyl or alkenyl optionally interrupted by O, S or NR, the functional groups including an aprotic polar group selected from the group consisting of sulfamide, a sulfonamide or phosphoramide groups.

2. A composition comprising a polyolefin including a plurality of functional groups, the functional groups including an aprotic polar group selected from the group consisting of sulfamide, sulfonamide or phosphoramide groups, wherein the polyolefin includes a polymer block selected from the group consisting of:

wherein n is 1 to 100,000 and X is a functional group including one or more sulfamide, sulfonamide, or phosphoramide groups, and Y is a bond or a C1-C6 alkyl or alkenyl optionally interrupted by O, S or NR, where NR is N-C1-C6 alkyl and including a moiety having one or more sulfamide, sulfonamide, or phosphoramide groups.

3. A composition comprising a polyolefin including a plurality of functional groups, the functional groups including an aprotic polar group selected from the group consisting of sulfamide, sulfonamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups, and wherein the polyolefin includes a polymer block selected from the group consisting of:

wherein n is 1 to 100,000 and X is a functional group including one or more sulfamide, sulfonamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups, and Y is a bond or a C1-C6 alkyl or alkenyl optionally interrupted by O, S or NR, where NR is N-C1-C6 alkyl and including a moiety having one or more functional group including sulfamide, sulfonamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups wherein X is a monovalent or divalent moiety having a structure selected from the group consisting of

4. The composition of claim 3 , wherein Y is a bond.

5. The composition of claim 3 , wherein Y is a C1-C6 alkyl or alkenyl optionally interrupted by O, S or NR, where NR is N-C1-C6 alkyl.

6. A battery including a composition of claim 3 .

7. A composition comprising a polyolefin including a plurality of functional groups, the functional groups including an aprotic polar group selected from the group consisting of sulfamide, sulfoxy, sulfonamide, carbonyl, phosphoramide or heterocyclic groups, and wherein the polyolefin includes a polymer block selected from the group consisting of:

8. The composition of claim 7 , wherein the polymer block is:

9. The composition of claim 7 , wherein the polymer block is:

10. The composition of claim 7 , wherein the polymer block is:

11. The composition of claim 7 , wherein the polymer block is:

12. The composition of claim 7 , wherein the polymer block is:

13. The composition of claim 7 , wherein the polymer block is:

14. The composition of claim 7 , wherein the polymer block is:

15. The composition of claim 7 , wherein the polymer block is:

16. The composition of claim 7 , wherein the polymer block is:

17. The composition of claim 7 , wherein the polymer block is:

18. The composition of claim 7 , wherein the polymer block is:

19. The composition of claim 7 , wherein the polymer block is:

20. The composition of claim 7 , wherein the polymer block is:

21. The composition of claim 7 , wherein the polymer block is:

22. The composition of claim 7 , wherein the polymer block is:

23. A battery having a composition comprising a polyolefin including a plurality of functional groups, the functional groups including an aprotic polar group selected from the group consisting of sulfamide, sulfonamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups, and wherein the polyolefin includes a polymer block selected from the group consisting of:

wherein n is 1 to 100,000 and X is a functional group including one or more sulfamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups, and Y is a bond or a C1-C6 alkyl or alkenyl optionally interrupted by O, S or NR, where NR is N-C1-C6 alkyl and including one or more functional group including sulfamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups.
