Abstract
Official abstract text for this publication.
The present invention relates to a cathode for a metal-air battery, a method for manufacturing the same, and a metal-air battery including the same. The cathode comprises a needle-shaped core including two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome, or a cobalt oxide; and a flake-shaped shell including an oxide containing two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome or a cobalt oxide. As such, the core-shell structure may lead to a reduction in the charge voltage of the metal-air battery as well as the taking of the good capacity characteristics of the transition metal oxide. Further, according to the present invention, the cathode for a metal-air battery may be produced without adding carbon or binder.
First claim
Opening claim text (preview).
What is claimed is: 1. A cathode for a metal-air battery, comprising: a needle-shaped core including two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome, or a cobalt oxide; and a flake-shaped shell including an oxide containing two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome or a cobalt oxide. 2. The cathode of claim 1 , wherein the core and the shell are formed on a porous support. 3. The cathode of claim 2 , wherein the porous support includes stainless steel or nickel.
