    摘要: Methods of forming an air electrode of a metal-air battery are provided. One method includes forming a plurality of layers of the air electrode. The plurality of layers include an active layer and a gas diffusion layer. Forming at least one of the active layer or the gas diffusion layer includes forming a first sublayer having a first concentration of a first material and forming a second sublayer having at least one of a second concentration of the first material that differs from the first concentration or a second material that differs from the first material. In another embodiment, a method includes forming a layer of an air electrode such that a gradient of a material is formed in at least a portion of the layer by varying a concentration of the material deposited between a first portion of the layer and a second portion of the layer.
