，
Is the trade name of Polyimide (PI) film material produced by DuPont, USA, and is available on the market, and polyimide can be obtained quickly and at low cost by applying the product.
Wherein, the porous substrate 20 of step 1(201) can be selected from one of the following: a porous carbon substrate, a porous graphite, a porous metal substrate, but not limited thereto; the pores 205 of the porous substrate 20 increase the overall substrate surface area.
Wherein, the liquid polyimide 11 obtained in step 1(201) is sprayed with mist particles of the polyimide 11 by ultrasonic spraying and then permeates into a porous substrate 20, as shown in fig. 2A, the mist particles of the liquid polyimide 11 are permeated into a porous substrate 20 by one or a plurality of ultrasonic sprayers 12; alternatively, as shown in fig. 6, at least one or a plurality of ultrasonic sprayers 12 are disposed inside the tunnel kiln 30 (including the inner side, the inner top or the inner bottom), and when the porous substrates 20 move on the conveyor belt 28, the plurality of ultrasonic sprayers 12 spray atomized mist particles of the liquid polyimide 11 onto the porous substrates 20 from various angles, so that the porous substrates 20 are attached with a polyimide layer 21 on the periphery of the plurality of pores 205 to form a porous coating substrate 22.

In another embodiment, as shown in FIG. 7A, the porous substrate 20 is a roll-to-roll substrate and has a first surface 207 and a second surface 208, the porous substrate 20 is disposed around a first shaft 302 and a second shaft 304, the first rotating shaft 302 and the second rotating shaft 304 are respectively disposed at the front end and the rear end of the conveyor belt 28, the porous substrate 20 is exposed with the first surface 207 upward, and is transported by the conveyor belt 28 into the tunnel kiln 30 to move, so that the first surface 207 of the porous substrate 20 receives the plurality of ultrasonic sprayers 12 to spray mist particles of the liquid polyimide 11 into the porous substrate 20, then, the tunnel kiln 30 is irradiated continuously by carbon dioxide laser from a plurality of carbon dioxide laser irradiators 32 to form a high-purity porous graphene layer 34 on the polyimide layer 21 of the porous coating substrate 22, and then the high-purity porous graphene layer is coiled on the second rotating shaft 304 at the rear end;
as shown in fig. 7B, the second rotating shaft 304 is moved, the porous substrate 20 wound around the second rotating shaft 304 is moved through a turning idler 29 to expose the second surface 208 of the porous substrate 20 upwards, the conveyor belt 28 is fed into the tunnel kiln 30 to move, the second surface 208 of the porous substrate 20 receives the plurality of ultrasonic sprayers 12 to spray the mist particles of the liquid polyimide 11 into the porous substrate 20, and then the tunnel kiln 30 receives the plurality of carbon dioxide laser irradiators 32 to continuously irradiate the carbon dioxide laser with the carbon dioxide laser, so that the polyimide layer 21 of the porous coating substrate 22 forms a high-purity porous graphene layer 34, which is then wound around a third rotating shaft 306, thereby forming a porous graphene substrate 36. In other words, the porous graphene substrate 36 includes: a porous substrate 20 having a plurality of pores 205; a plurality of high purity porous graphene layers 34, the plurality of high purity porous graphene layers 34 attached to the periphery of the plurality of pores 205.
The plurality of carbon dioxide laser irradiators 32 in the above steps 2(202) continuously irradiate the porous coating substrate 22 passing through the tunnel kiln 30 with carbon dioxide laser light, so that the polyimide layer 21 of the porous coating substrate 22 forms a high-purity porous graphene layer 34 because: the polyimide layer 21 is irradiated with a carbon dioxide laser beam to absorb energy, thereby vibrating the atomic lattice of the polyimide 11, breaking the bonds between C ═ O and N — C in the molecules thereof, and rearranging the atoms of the Aromatic compounds (Aromatic compounds) to form a porous graphene layer 34; since the polyimide 11 includes aromatic and imide (aromatic nitrile), the polyimide 11 may eventually form the porous graphene layer 34.
In the step 3(203), the porous graphene substrates 36 are subjected to a lithiation process to form a plurality of lithiated graphene electrodes 38 on the porous graphene substrates 36, wherein lithiation refers to intercalation of lithium ions into gaps between graphene layers of the porous graphene substrates 36, so that lithium ions are conveniently deintercalated during discharge and intercalated during charge when the porous graphene substrates are used as a negative electrode. In other words, the porous graphene substrate 36 further has a structure of a lithiated graphene electrode 38, and the lithiated graphene electrode 38 is a plurality of high-purity porous graphene layers 34 of the porous graphene substrate 36, wherein gaps exist between the layers, and a plurality of lithium ions are inserted into the gaps.

C＝εA/D，
wherein C is capacitance, A is the area of the parallel plates, D is the distance between the parallel plates, epsilon is the dielectric constant between the parallel plates,
since the porous graphene substrate 36 has more gaps and pores than a general electrode and thus has a larger surface area, the larger the capacitance, and thus the larger the capacitance, which makes it to be used as the electrode plate 42 of the supercapacitor 40.
Moreover, another second electrode plate 46 of the super capacitor 40 can also be made of a porous graphene substrate 36 as the second electrode plate 46, and the surface area thereof is also large, which can also make the capacitance of the super capacitor 40 larger.
As shown in fig. 10, in an embodiment, after the formation of the lithiated graphene electrode 38 in step 3(203), the lithiated graphene electrode 38 may serve as a negative electrode 52 of a lithium ion battery 50; because the lithiated graphene electrode 38 has a plurality of graphene layer-to-layer gaps, more lithium ions can be inserted into the gaps, and the lithium ion battery 50 has a larger capacity of storage as the negative electrode 52. The lithium ion battery 50 in fig. 10 is illustrated by taking a polymer lithium ion battery as an example, and the polymer lithium ion battery also belongs to a general lithium ion battery 50, except that the electrolyte of the polymer lithium ion battery is a solid electrolyte. The general lithium ion battery 50 is mainly composed of a positive electrode 56, a negative electrode 52, a separator 54(separator), and the like. The polymer lithium ion battery is also composed of a positive electrode 56, a negative electrode 52, a separator 54(separator), and the like, and the separator 54 is compatible with a solid electrolyte.
Further, after the plurality of lithiated graphene electrodes 38 are stacked into the multi-layered lithiated graphene electrode 39, the multi-layered lithiated graphene electrode 39 has more gaps between graphene layers than the single-layered lithiated graphene electrode 38, so that more lithium ions can be inserted into the gaps, and the multi-layered lithiated graphene electrode can be used as the electrode plate 42 of the lithium ion battery 50 to have a larger storage capacity.
In one embodiment, after the formation of the lithiated graphene electrode 38 in step 3(203), the lithiated graphene electrode 38 may be used as a negative electrode of a super capacitor Lithium Battery (ultra capacitor Lithium Battery), because the lithiated graphene electrode 38 has a plurality of graphene layer-to-layer gaps, which allows more Lithium ions to be inserted into the gaps, so that the Lithium ion storage capacity of the Lithium ion Battery is larger as a negative electrode of the super capacitor Lithium Battery.
The manufacturing device of the graphene electrode plate of the utility model, by means of the above-mentioned structural design, can make the porous graphene substrate 36 and the lithiated graphene electrode 38 have the feasibility of mass production; the lithiated graphene electrode 38 can be used as a negative electrode 52 of the lithium ion battery 50, so that the lithium ion battery 50 can have a larger storage capacity as an electrode plate 42; the porous graphene substrate 36 can be used as an electrode plate 42 of a super capacitor 40, so that the capacitance of the electrode plate 42 of the super capacitor 40 is larger; the lithiated graphene electrode 38 can be used as a negative electrode of a super capacitor lithium battery, so that the production and application of the process method of the graphene electrode of the utility model achieve excellent economic benefit.
