Lanthanum nickel compound/metal mixture as a third electrode in a metal-air battery

A third electrode for use in a metal-air tricell comprising a support structure coated with a layer of a mixture of a lanthanum nickel compound and at least one metal,

• wherein the mixture is adhered to the support structure without the use of an adhesive and the support structure is composed of a series of rigid rods or wires.

A method of forming a third electrode for use in a metal-air tricell comprising the steps of:

• (A) applying a mixture of a lanthanum nickel compound and at least one metal oxide to a support structure, thereby yielding a coated support structure;
• and
• (B) heating the coated support structure in order to reduce the metal oxide present in the lanthanum nickel compound/metal oxide mixture to its corresponding metal and to adhere the lanthanum nickel compound/metal mixture to the support structure, thereby yielding a third electrode wherein the third electrode is free of an adhesive.

A method of forming a third electrode for use in a metal-air tricell comprising the steps of:

• (A) forming a suspension of a lanthanum nickel compound, at least one metal oxide compound and at least one dispersant;
• (B) applying the lanthanum nickel compound/metal oxide suspension to a support structure, thereby yielding a coated support structure;
• (C) heating the coated support structure to drive off the dispersant, reduce the metal oxide present in the lanthanum nickel compound/metal oxide suspension to its corresponding metal and to adhere the resulting lanthanum nickel compound/metal mixture to the support structure, thereby yielding a third electrode wherein the third electrode is free of an adhesive.
