Abstract
A positive electrode for a lithium air battery includes a current collector, and a positive electrode catalyst layer on the current collector. The positive electrode catalyst layer includes a first conductive material supported on a binder, a second conductive material on the first conductive material, and a catalyst supported on the second conductive material.
Claims15
A positive electrode for a lithium air battery, the positive electrode comprising:
- a current collector;
- and
- a positive electrode catalyst layer on the current collector, the positive electrode catalyst layer including a first conductive material supported on a binder and a catalyst supported on a second conductive material,
- wherein the catalyst is spaced apart from the binder such that the first conductive material is between the binder and the catalyst.

A method of preparing positive electrode for a lithium air battery, the method comprising:
- supporting a first conductive material on a binder to form a first conductive material supported on a binder;
- mixing the binder having the first conductive material supported thereon and a second conductive material, such that the second conductive material has a catalyst supported thereon and the catalyst is spaced apart from the binder, the first conductive material being between the binder and the catalyst;
- adding the resultant mixture to a solvent to prepare a catalyst composition;
- and
- coating a current collector with the catalyst composition.
