A patent application (Publication Number: US20240039006A1) discloses a catalyst for use in metal-air batteries, comprising particles made of a metal oxide (such as iron oxide or manganese oxide) and a carbonaceous material (like graphene). The metal oxide can be selected from various forms of iron and manganese oxides, while the carbonaceous material can include graphene, graphene oxide, and nanoplatelets of graphene. The catalyst particles have a size range of 10 to 300 nm, with the weight proportion of the carbonaceous material and metal oxide falling between 20% and 80%. Additionally, the catalyst can be a bifunctional catalyst, suitable for use in metal-air batteries.
Furthermore, the patent application describes a metal-air battery configuration with a metal electrode (e.g., Fe, Zn, Al) and an air electrode containing the aforementioned catalyst. The electrolyte used in the battery can be an aqueous solution or a gel with a pH greater than 7, or a membrane electrolyte that transports hydroxyl groups. The amount of catalyst applied on the air electrode ranges from 1 to 50 mg/cm2. The patent also specifies variations in the surface area of the carbonaceous material and the weight proportions of the carbonaceous material and metal oxide in the catalyst. Notably, one claim highlights the use of zinc as the metal electrode in the metal-air battery setup.
