Abstract

Disclosed herein is a battery anode compound including a metal oxide and a metal. Also disclosed herein is a method of providing a battery anode compound comprising synthesizing AlNb 11 O 29 and combining AlNb 11 O 29 and a metal. A Li-ion battery anode compound is also disclosed that includes a slurry comprising up to 70% AlNb 11 O 29 , up to 70% Li 4 Ti 5 O 12 , and up to 70% of a metal, wherein the metal is any one of Sb or Sn.

Claims (37)

1 . A battery anode compound, comprising:

a metal oxide comprising greater than 0% by weight and less than or equal to 70% by weight of the battery anode compound; and

a metal comprising at least one of a Group IVA metal and a Group VA metal, the metal comprising greater than 0% by weight and less than or equal to 70% by weight of the battery anode compound.

2 . The battery anode compound of claim 1 , wherein the metal oxide is an oxide of a Group IIIA-VB metal alloy.

3 . The battery anode compound of claim 1 , wherein the metal oxide is an oxide of a Group IA-IVB metal alloy.

4 . The battery anode compound of claim 1 , wherein the metal oxide is an oxide of a Group IA-VB metal alloy.

5 . The battery anode compound of claim 1 , wherein the metal oxide is AlNb 11 O 29 .

6 . The battery anode compound of claim 1 , wherein the metal is Sn.

7 . The battery anode compound of claim 1 , wherein the metal is Sb.

8 . The battery anode compound of claim 1 , wherein the metal oxide is AlNb 11 O 29 and the metal is Sn.

9 . The battery anode compound of claim 1 , wherein the metal oxide is AlNb 11 O 29 and the metal is Sb.
