Abstract
A metal-air battery according to the present disclosure includes an electrode assembly with a first electrode layer having a length and being folded lengthwise, and a gas diffusion layer having a length that is approximately half the length of the first electrode layer. Furthermore, the gas diffusion layer is positioned proximate the first electrode layer or between first and second portions of the first electrode layer.
Claims20
A metal-air battery comprising:
- an electrode assembly including a first electrode layer having a length and being folded lengthwise, and a gas diffusion layer having a length that is approximately half the length of the first electrode layer, the gas diffusion layer being positioned proximate the first electrode layer or between first and second portions of the first electrode layer.
A metal-air battery comprising:
- an electrode assembly including an air electrode layer having a length and being folded lengthwise, a negative electrode layer positioned between first and second portions of the folded air electrode layer, and a gas diffusion layer having a length that is approximately half the length of the air electrode layer, the gas diffusion layer being positioned proximate the air electrode layer.
A metal-air battery comprising:
- an electrode assembly including a negative electrode layer having a length, an air electrode layer having a length that is approximately the same as the length of the negative electrode layer, and a gas diffusion layer having a length that is approximately half the length of the negative electrode layer, wherein the negative electrode layer and the air electrode layer are folded lengthwise over the gas diffusion layer such that the gas diffusion layer is positioned between two portions of each of the negative electrode layer and the air electrode layer.
