Embodiment 1
[0040] Step 1. Weld one end of the metal foil with a width of 40-250mm to a wire with a diameter of 0.5-5mm and a length of 60-300mm; spread the carbon film with a width of 40-250mm on the metal foil that has been welded with the wire Above, rotate the metal wire connected with the metal foil, wind the metal foil covered with carbon film on the metal wire along the direction of rotation of the metal wire, and use the compaction mold to compact the metal foil, carbon film and metal wire to make the three Closely fit, that is, the preparation of the winding assembly is completed;
[0041] Step 2: Put the winding assembly prepared in step 1 into a cleaned metal tube with an expected matching diameter, and encapsulate the two ends of the metal tube;
[0042] Step 3. The metal / carbon composite rod packaged in Step 2 is subjected to high-temperature treatment. The treatment process is always under an atmosphere of inert gas and hydrogen. The treatment temperature is lower than the m...

[0048] Step 1. Select a copper wire with a diameter of 0.5 mm and a length of 150 mm, and weld one end of a copper foil with a width of 120 mm and a thickness of 10 μm to the copper wire; spread a graphene film with a thickness of 100 μm and a width of 120 mm on the existing On the copper foil welded with copper wire, turn the copper wire, wind the copper foil covered with graphene film on the copper wire along the direction of copper wire rotation, and use the compaction die to squeeze the graphene film, copper foil and copper wire , so that the three are closely attached, that is, the preparation of the winding assembly is completed, and the diameter of the winding assembly is 4mm;
[0049] Step 2. Put the wound assembly obtained in Step 1 into a cleaned oxygen-free copper tube with an inner diameter of 4 mm and a wall thickness of 0.2 mm, and seal both ends of the oxygen-free copper tube;
[0050] Step 3. The copper / graphene composite rod packaged in step 2 is subjected to ...

[0055]Step 1. Select a copper wire with a diameter of 5 mm and a length of 300 mm, and weld one end of an aluminum foil with a width of 250 mm and a thickness of 100 μm to the aluminum wire; spread a carbon nanotube film with a thickness of 3 μm and a width of 250 mm on the On the aluminum foil welded by copper wire, turn the copper wire, wind the aluminum foil covered with carbon nanotube film on the copper wire along the direction of the copper wire, and use the compaction die to extrude the carbon nanotube film, aluminum foil and copper wire to make the three or close fit, that is, the preparation of the winding assembly is completed, and the diameter of the winding assembly is 8mm;
[0056] Step 2. Put the winding assembly completed in step 1 into a cleaned oxygen-free aluminum tube with an inner diameter of 8 mm and a wall thickness of 0.5 mm, and seal both ends of the oxygen-free aluminum tube;
[0057] Step 3. The aluminum / carbon nanotube / copper composite rod packaged i...
