Claim 10:
11. A method of producing a zinc anode, comprising the steps of:
providing copper ink,
creating a 3D model of the zinc anode wherein said step of creating a 3D model of the zinc anode includes producing stacked parallel elements with multiple layers and creating a 3D log pile model of the zinc anode,
3D printing said copper ink into a porous copper lattice structure using said 3D model producing stacked parallel elements with multiple layers and a 3D log pile of the zinc anode,
heat treatment of said porous copper lattice structure producing a heat treated porous copper lattice structure having stacked parallel elements with multiple layers and a 3D log pile of the zinc anode,
surface modification of said heat treated porous copper lattice structure by nanowires growth on said heat treated porous copper lattice structure producing a heat-treated porous copper lattice structure with nanowires having stacked parallel elements with multiple layers and a 3D log pile of the zinc anode, and
electrodeposition of zinc onto said heat treated porous copper lattice structure with nanowires to produce the zinc anode having stacked parallel elements with multiple layers and a 3D log pile of the zinc anode.
