An anode for an aluminium-air battery, comprising an anode body which contains particles of an aluminium alloy embedded in a sodium matrix, wherein the anode body has flow-guiding structures configured to enable a torque to be transmitted to the anode from an electrolyte flow, the flow-guiding structures being in the form of screw-shaped vanes or vane sections.
A method for manufacturing an anode for an aluminium-air battery, comprising:
- embedding particles of a granular material comprising an aluminium alloy into a sodium matrix;
- and
- casting an anode body of the anode comprising the sodium matrix with the granular material, the anode body having flow-guiding structures in the form of screw-shaped vanes or vane sections, the flow-guiding structures configured to enable a torque to be transmitted to the anode from an electrolyte flow.
A metal-air battery, comprising:
- a housing having an electrolyte inlet and an electrolyte outlet;
- a cathode separating an air space from an electrolyte space in the housing;
- an anode;
- an electrolyte disposed between the cathode and the anode;
- wherein the anode includes an anode body which contains particles of an aluminium embedded alloy in a sodium matrix;
- wherein the electrolyte consists of one of an aqueous acid or an aqueous lye containing at least one halogen and at least one surfactant;
- and
- wherein the electrolyte inlet arranged tangentially to an electrolyte space;
- and wherein the anode body has flow-guiding structures configured to enable a torque to be transmitted to the anode from a flow of the electrolyte, the flow-guiding structures being in the form of screw-shaped vanes or vane sections.
