Abstract
A method of manufacturing a porous composite electrode including: preparing an ink including a carbon material and a binder; coating a substrate with the ink to manufacture a composite electrode; and irradiating the composite electrode with microwave to remove the binder and an organic material, and a method of removing an organic material of a porous composite electrode.
Claims8
A method of manufacturing a porous carbon composite electrode, the method comprising:
- a) preparing an ink including a solvent, a binder and two or more porous carbon materials;
- selected from the group consisting of single-walled carbon nanotubes, multi-walled carbon nanotubes, single-layer graphene and multi-layer graphene;
- b) coating a porous metal foam substrate with the ink to provide an intermediate product comprising an ink layer on the porous metal foam substrate, and drying the ink layer to remove the solvent;
- c) irradiating microwaves onto the ink layer to selectively remove the binder without deforming the porous metal foam substrate and the two or more porous carbon materials to provide the porous composite electrode comprising a porous carbon layer on the porous metal foam substrate;
- and
- d) removing the porous metal foam substrate with a metal etching solution, thereby forming the porous carbon composite electrode consisting of a composite of the two or more porous carbon materials;
- wherein the binder is at least one selected from the group consisting of polytetrafluoroethylene, polyvinylidene fluoride and polypyrrole.
