Abstract

A composition for forming an electrode. The composition includes a hybrid active material compound doped with a dopant. The hybrid active material comprises the reaction product of a metal fluoride compound and a metal complex. A method of making the composition is included.

First claim

We claim:

1. An electrode, comprising:
a reaction product of a metal fluoride compound, a metal complex, and a doping precursor, wherein the doping precursor comprises a metal and wherein the electrode has rechargeable capacity.

2. The electrode of claim 1 wherein the doping precursor is present in the rection product at an amount of 0.1 equivalents or less.

3. The electrode of claim 1 wherein the metal of the doping precursor is a transition metal.

4. The electrode of claim 3 wherein the transition metal is iron.

5. An electrode, comprising:
a reaction product of a metal fluoride compound, a metal complex, and a doping precursor, wherein the doping precursor comprises a post-transition metal.

6. The electrode of claim 5 wherein the post-transition metal is aluminum.

7. The electrode of claim 5 wherein the post-transition metal is bismuth.

8. The electrode of claim 1 wherein the metal fluoride compound comprises copper fluoride.

9. The electrode of claim 1 wherein the metal complex comprises a metal oxide.

10. The electrode of claim 9 wherein the metal complex comprises nickel oxide.

11. A method of making an electrode, comprising:
reacting a metal fluoride compound, a metal complex, and doping precursor to form a doped reaction product, wherein the doping precursor comprises a metal and the reacting includes a milling step; and
forming the doped reaction product into an electrode having rechargeable capacity.

12. The method of claim 11 wherein the metal fluoride compound comprises copper fluoride.

13. The method of claim 11 wherein the metal complex comprises a metal oxide.

14. The method of claim 13 wherein the metal complex comprises nickel oxide.

15. The method of claim 11 wherein the metal of the doping precursor is a transition metal.

16. The method of claim 15 wherein the transition metal is iron.

17. The method of claim 11 wherein the metal of the doping precursor is a post-transition metal.

18. The method of claim 17 wherein the post-transition metal is aluminum.

19. The electrode of claim 1 wherein the doping precursor is a metal fluoride, wherein the metal fluoride of the doping precursor has a different composition than the metal fluoride compound of the reaction product.

20. The electrode of claim 1 wherein the doping precursor includes one or more of CoF 3 , FeF 2 , FeF 3 , A 1 F 3 , BiF 3 , YF 3 , LaF 3 , TiF 3 , TiF 4 , NbF 5 , TaF 5 , CrF 2 , CrF 3 , AgF 2 , ZnF 2 , CdF 2 , Hg 2 F 2 , HgF 2 , GaF 3 , InF 3 , SnF 2 , SnF 4 , SbF 3 , or CeF 3 .
