Abstract: The present disclosure relates to a manufacturing method of a micro 3D current collector using laser direct energy deposition and a manufacturing method of a 3D electrode for a supercapacitor, particularly to a manufacturing method of a micro 3D current collector using laser direct energy deposition where micro-metallic structures are directly printed onto a substrate using a laser-based direct energy deposition process, and then used as the current collectors of the micro-supercapacitors. The current collector with printed micro-metallic wires possesses high electric conductivity and a high aspect ratio as well as a larger surface area due to the extensive surface area of the wires, making it suitable for depositing energy storage active materials.
