specific Embodiment approach

[0011] Step 1 Selection and installation of target and support layer

[0012] The selected target is installed on the lower target seat in the pulse magnetron sputtering coating chamber; the organic film is used as the support layer, and it is installed at the upper center of the coating chamber, and the vertical distance from the target is 20-90mm.

[0013] Step 2 Vacuuming and supporting layer heating

[0014] First start the mechanical pump, and after 15 to 40 minutes, when the air pressure in the coating chamber is less than 30Pa, open the solenoid valve and the molecular pump in sequence, close the side pump valve, and open the gate valve; after 40 to 70 minutes, when the air pressure reaches ~ 10 -3 Pa, start the heating power supply, slowly adjust the current from small to large (I max =11.5A), increase the heating rate. The back vacuum is 1×10 -4 ~1×10 -5 Pa, the temperature of the support layer is controlled at 30°C to 300°C.

[0015] Step 3 Fill working gas and...

Description

technical field [0001] The invention belongs to the technical field of new materials and relates to the structure of a class of current collector materials. Background technique [0002] In recent years, with the rapid development of electronic technology, new electronic products continue to appear, and the market for batteries and supercapacitors is also expanding. In particular, the combination of supercapacitors and batteries used in electric vehicles can provide a more powerful and reliable system for starting the car engine, and can store the energy during braking, which can be used again for the next acceleration and support acceleration. In order to be widely used in power tools, electric vehicles and other fields, the power density and energy density of these batteries and supercapacitors need to be further improved. Usually batteries and supercapacitors are assembled from electrodes, electrolytes, separators, current collectors, and casings. The main factors restr...
