- where M is selected from the group of monovalent elements consisting of lithium, sodium, potassium, silver, and copper and wherein n is a number in the range of about 0.4 to about 0.6.
- 2. The anode structure as defined in claim 1 wherein M is lithium.
- 3. The anode structure as defined in claim 1 wherein M is sodium.
- 4. The anode structure as defined in claim 1 wherein M is potassium.
- 5. The anode structure as defined in claim 1 wherein M is silver.
- 6. The anode structure as defined in claim 1 wherein M is copper.
- 7. The anode structure as defined in claim 1 where n is about 0.5.
- 8. The anode structure as defined in claim 1 wherein said basis metal is a valve metal.
- 9. The anode structure as defined in claim 1 wherein said basis metal is titanium.
- 10. The anode structure as defined in claim 1 wherein said basis metal is layered with a metal selected from the group consisting of platinum and platinum alloys.
- 11. The anode structure as defined in claim 1 wherein said cover layer additionally comprises a binder stable in contact with the media of an electrolysing brine.
- 12. The anode structure as defined in claim 1 wherein said cover layer additionally comprises a material which increases the electrical conductivity of the layer and which is stable in contact with the media of an electrolysing brine.
- 13. The anode structure as defined in claim 11 wherein said binder comprises up to about 85% by weight of said cover layer.
- 14. The anode structure as defined in claim 12 wherein said material comprises up to about 85% by weight of said cover layer.
- 15. The anode structure as defined in claim 1 wherein said cover layer additionally comprises up to about 85% by weight of a mixture of a binder and a material which improves the electrical conductivity of the layer wherein said binder and said material are stable in contact with the media of an electrolysing brine.
- 16. The anode structure as defined in claim 1 wherein n is about 0.5 and said basis metal is a valve metal.
