Description

Technical Field

[0001] The present invention relates to the field of carbon nano electrostatic spinning, and in particular to an electrostatic spinning production device and a preparation method for a carbon nanowire composite electrode. Background Art

[0002] Carbon nanowire composite electrodes are primarily used as electrode materials in zinc-ion batteries. The scarcity and cost of lithium metal resources have led to an urgent need to develop new, cost-effective, environmentally friendly, and energy-dense secondary battery systems. Aqueous zinc-ion batteries, due to their low cost, high safety, low redox potential (-0.76 V SHE H), and high theoretical specific capacity of the zinc anode (820 mAh g⁻¹), have become the most competitive alternative to lithium-ion batteries. Therefore, carbon nanowire composite electrodes play a crucial role in the development of zinc-ion batteries.

[0003] In the document with publication number CN107503000A, a method for preparing nanocarbon fiber bundles by electrospinning is proposed: "by regulating the appropriate concentration of polyacrylonitrile solution, a highly oriented nano-yarn is prepared by a fluid-assisted electrospinning process, and the resulting yarn is then post-drawn and finally carbonized at high temperature under an inert atmosphere to obtain nanocarbon fiber bundles." The method is to modify the nano-yarn at high temperature, but precise control of the temperature during high-temperature modification is crucial. If the temperature is too high, the fiber structure may be damaged, while if the temperature is too low, the expected performance improvement effect will not be achieved. At the same time, the atmosphere control during the heat treatment process will also affect the surface chemical properties and microstructure of the material.

[0004] Laboratory-scale electrospinning equipment has a low output and is difficult to meet the needs of industrial-scale large-scale production. To achieve large-scale production, it is necessary to develop efficient spinning equipment, such as multi-nozzle spinning systems and continuous spinning devices. However, the design and manufacture of these devices need to take into account issues such as mutual interference between multiple nozzles, uniform solution supply, and continuous fiber collection, which are technically difficult.

[0023] A method for producing an electrostatic spinning carbon nanowire composite electrode comprises placing a mixed solution of V2O3 and nitrogen-doped carbon nanowires into a mixed liquid tank, and directing the mixed liquid into an infusion tube via an infusion pump on a control host.

[0024] The first conductive clamp holds the first conductive core, and the second conductive clamp holds the other conductive core on the nozzle to form an electric field. The solution in the infusion tube is ejected through the nozzle for spinning, confining V2O3 in the carbon nanowires.

[0025] The spinning disk rotates to collect the ejected filaments, which are then collected by a guide rod with a diameter of 0.5 cm and a length of 10-15 cm. The filaments then pass through the first and second guide rollers in an S-shaped trajectory. The burrs on the edges of the spun nanowires are removed when the filaments pass through the burr removal mechanism. The filaments then pass through the third and fourth guide rollers in the same S-shaped trajectory for guidance.

[0026] According to the thickness and diameter of the finished spinning product, the corresponding adjustment hole on the adjustment plate is selected and inserted. Then, the ring is passed through the sleeve hole. The pusher mechanism is activated, and the insulating ring passing through the nanowire is lowered into the electrolyte tank for electrochemical annealing. During the electrochemical conversion of V2O3 to V2O5, the carbon nanowires can act as a "protective structure" to effectively prevent the formation of by-products, thus constructing a pea-pod-shaped nitrogen-doped carbon nanowire-coated amorphous V2O5 microspheres as a free-standing electrode material.

[0027] The nanowires that have completed electrochemical annealing continue to pass through the first guide hole and the second guide hole. The heating wire and the heating fan in the evaporation hood work together to form hot air for rapid drying, and the water vapor is discharged through the exhaust fan.

[0028] The dried nanowires pass through the wire hole and fit on the upper limit of the wire roller. The collected drum collector or the prepared collector is installed in the rotating rod and fixed by the positioning clamp. As the rotating rod rotates, the nanowires are wound up.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] First, by setting up six groups of guide gears, the six spinning disks can be driven to spin, achieving efficient spinning. The spinning mechanisms distributed corresponding to the spinning disks are used for feeding and spinning. The first conductive clamp clamps the first guide core for conductivity, and the second conductive clamp clamps the other guide core on the nozzle. The six groups of second conductive clamps clamp the nozzle and the first guide core to form six circulating electric fields to achieve zoned spinning.

[0031] Secondly, by driving the first transmission gear and the first transmission bevel gear on the motor to rotate synchronously, the driving rod and the burr collection gear are driven to rotate. When the engaging gear on the driving rod contacts the linkage gear, linkage is achieved, and multiple sets of linkage gears are driven to make the upper cutting blades rotate, thereby collecting debris while removing burrs.

[0032] Third, the rotation of the outer wheel drives the connecting arm on the first rotating ring to move, and the connecting arm detaches from the second rotating ring to drive the six sets of adjustment plates to expand synchronously. At this time, the nanowires set in the adjustment holes can adjust their own tension. The nanowires can flexibly form a tight or loose state. After being fixed by the insertion rod and the corresponding card hole, the rotation angle of the first rotating ring on the outer wheel is fixed.

[0033] Fourthly, by the up and down sinking of the nanowires in the holes on the insulating ring, the nanowires can be immersed in the electrolyte tank during production, and electrochemical annealing can be completed in conjunction with the electrolyte and the voltage released by the first electrode position and the second electrode position.

[0034] Fifth, through the operation of the heating wire and the heating fan in the evaporation hood, the heat flow can be fully and evenly directed to every direction in the drying chamber. The nanowires located at the periphery of the evaporation hood are dried during the movement through heat evaporation, avoiding the moisture of the modified nanoelectrodes affecting the storage.

The tension adjustment mechanism 54 includes a first rotating ring 541, which is connected to the outer rotating wheel 51. Six groups of connecting arms 542 are distributed on the first rotating ring 541 and are rotatably connected thereto. A first latch 543 and a second latch 544 are respectively installed at both ends of the connecting arm 542. An adjustment piece 545 is connected to the second latch 544. The adjustment piece 545 is distributed with multiple groups of adjustment holes 546 of different diameters. The adjustment holes 546 of different diameters are arranged on the upper adjustment piece 54 5 are marked as a, b, c, d, e, and f respectively. There are six groups of adjustment pieces 545. A single adjustment piece 545 has a triangular structure and its edge is arc-shaped. A third pin 548 is provided on the adjustment piece 545 and is connected to the second rotating ring 547. The rotation of the outer rotating wheel 51 drives the connecting arm 542 on the first rotating ring 541 to move. The connecting arm 542 is separated from the second rotating ring 547 and drives the six groups of adjustment pieces 545 to be synchronously expanded. At this time, the nanowires set in the adjustment holes 546 can adjust their own tension, and the nanowires can flexibly form a tight or loose state.

[0075] The tension adjustment chamber 5 is connected to the annealing chamber 6, and the annealing chamber 6 is provided with a second chamber door 61. The second chamber door 61 is opened to enable the carbon nanowires to be threaded in the annealing chamber 6. An electrolyte chamber 63 is installed at the lower end of the annealing chamber 6. The first electrode position 64 and the second electrode position 65 are respectively connected to the two sides of the electrolyte chamber 63. The voltage released by the first electrode position 64 and the second electrode position 65 using the electrolyte as the medium is used to electrochemically anneal the spun carbon nanowire composite electrode. During the electrochemical conversion of V2O3 to V2O5, the carbon nanowires can act as a "protective structure" to effectively prevent the formation of by-products, thereby constructing a pea-pod-shaped nitrogen-doped carbon nanowire-coated amorphous V2O5 microsphere independent electrode material.

[0076] A pushing mechanism 62 is provided above the electrolyte tank 63, and the pushing mechanism 62 includes a control motor 621, an electric telescopic rod 622, an insulating ring 623 and a sleeve hole 624.

The insulating ring 623 is distributed with sleeve holes 624. The insulating ring 623 forms a vertical telescopic structure with the electrolyte tank 63 through the electric telescopic rod 622. The nanowires in the sleeve holes 624 on the insulating ring 623 sink up and down, so that the nanowires can be immersed in the electrolyte tank 63 during production.

[0077] The annealing chamber 6 is connected to the drying chamber 7, and the drying chamber 7 is provided with a third chamber door 71. Two sets of exhaust fans 72 are distributed on the top of the drying chamber 7. A filtering mechanism can be set according to the composition of the electrolyte to determine whether it is harmful. This direction is not an improvement point of this solution, and the existing technology is mature, so it has not been expanded too much. A first guide frame 73 and a second guide frame 74 are respectively provided on both sides of the drying chamber 7. The first guide frame 73 is connected to the annealing chamber 6 and is provided with six groups of first guide holes 731 distributed in a circular array with the first guide frame 73 as the center. The second guide frame 74 is provided with second guide holes 741 corresponding to the first guide holes 731. A drying hood 75 is mounted on the second guide frame 74.

A wire roller 762 is mounted in the middle of the wire hole 761. A heating wire 77 and a heating fan 78 are mounted inside the drying hood 75 close to one end of the wire bin 76. The operation of the heating wire 77 and the heating fan 78 in the drying hood 75 can fully and evenly guide the heat flow to every direction in the drying bin 7. When the nanowires located at the periphery of the drying hood 75 pass by, the heat flow evaporates on the moving nanowires to complete the drying.

[0078] A side bracket body 8 is installed on the bottom frame close to the drying bin 7, and a collecting device 9 is provided on the side bracket body 8. A second servo motor 91 is provided on the collecting device 9 and is fixedly installed with the side bracket body 8. A first steering gear 92 is installed at the output end of the second servo motor 91. Six groups of second steering gears 96 meshing with the first steering gear 92 are connected to the first steering gear 92. The second steering gear 96 is connected to a rotating rod 94. A limiting frame 93 fixed to the side bracket body 8 is provided on the rotating rod 94. A thread is provided on the rotating rod 94, and a matching positioning clamp 95 is connected to it. The collected drum collector or the prepared collector is installed in the rotating rod 94. The installation of the positioning clamp 95 on the rotating rod 94 fixes and clamps the collector. As the rotating rod 94 rotates, the nanowires are wound up.

[0079] Reference Figures 1 to 21 The present invention provides a technical solution: a method for producing an electrospinning carbon nanowire composite electrode, wherein a solution mixed with V2O3 and nitrogen-doped carbon nanowires is placed in a mixed liquid tank 2, and the mixed liquid is guided to an infusion tube 414 through an infusion pump 103 on a control host 1;

[0080] The first conductive clamp 36 clamps the first conductive core 35, and the second conductive clamp clamps the other conductive core on the nozzle to form an electric field. The solution in the infusion tube 414 is sprayed through the nozzle for spinning, confining V2O3 in the carbon nanowires.

[0081] The spinning disk 34 rotates to collect the ejected filaments, which are then collected by a guide rod with a diameter of 0.5 cm and a length of 10-15 cm. The filaments are then collected by a guide rod with an S-shaped trajectory and pass through the first guide roller 421 and the second guide roller 422. The burrs on the edges of the spun nanowires are removed by a burr removal mechanism 425.

[0082] According to the thickness and diameter of the finished spinning product, the corresponding adjustment hole 546 on the adjustment plate 545 is selected and passed through, and then passed through the sleeve hole 624. The pusher mechanism 62 is activated, and the insulating ring 623 passing through the nanowire is sunk into the electrolyte tank 63 for electrochemical annealing. During the electrochemical conversion of V2O3 to V2O5, the carbon nanowire can act as a "protective structure" to effectively prevent the formation of by-products, thereby constructing a pea-pod-shaped nitrogen-doped carbon nanowire-coated amorphous V2O5 microsphere independent electrode material;

[0083] The nanowires that have completed electrochemical annealing continue to pass through the first guide hole 731 and the second guide hole 741 . The heating wire 77 and the heating fan 78 in the drying cover 75 cooperate to form hot air for rapid drying, and the water vapor is discharged through the exhaust fan 72 .

[0084] The dried nanowires pass through the wire hole 761 and fit on the upper limit of the wire roller 762. The collected drum collector or the prepared collector is installed in the rotating rod 94 and fixed by the positioning clamp 95. As the rotating rod 94 rotates, the nanowires are wound.

[0085] Working principle: Before the equipment starts spinning production, the first chamber door 43, the second chamber door 61 and the third chamber door 71 will be opened one by one, and the electrolyte will be injected into the electrolyte chamber 63, thus completing the basic preparations for the operation of the equipment before spinning;

[0086] The original solution mixed with V2O3 and nitrogen-doped carbon nanoparticles is placed in the mixed liquid tank 2. The liquid guide port 202 is connected to the liquid receiving port 104. The infusion pump 103 pumps the liquid into the infusion tube 414. The mixed liquid tank 2 has a large capacity and can accommodate more spinning solution. The liquid inlet 201 on it can also be directly opened for direct injection and replenishment, avoiding the impact of injection and replenishment on the operation of the equipment.

[0087] The driving gear 32 on the first servo motor 31 rotates, meshing and driving the spinning disk 34 installed on the six sets of guide gears 33 around it to rotate continuously. The wind flow generated by the rotation of the spinning disk 34 forms a vortex. The nozzle 413 receives the spinning solution input from the infusion tube 414. The first conductive clamp 36 clamps the first guide core 35, and the second conductive clamp 415 clamps the other guide core on the nozzle 413 to form an electric field. The six spinning mechanisms 41 control the formation of six circulating and relatively independent electric fields. The solution in the infusion tube 414 is sprayed out through the nozzle 413 for spinning, and the spun nanofilaments are concentrated on the spinning disk 34. A guide rod with a diameter of 0.5 cm and a length of 10-15 cm is used to collect the rotating silk near the spinning disk 34 and pull it to form a silk thread. As the spinning disk 34 rotates, it gradually becomes tighter and passes the formed nanofilament through the first guide roller 421 and the second guide roller 422 in an "S"-shaped trajectory;

[0088] Similarly, it passes between the second guide roller 422 and the third guide roller 423 in an "S"-shaped trajectory, pushes and pulls the tooth plate 4253, and its upper teeth come into contact with the expansion teeth 4257c. When the tooth plate 4253 is pushed up to the top, the arc frame 4257b is fully expanded, and the second limiting magnetic piece 4253b is adsorbed and fixed to the upper limit of the operating table 4252. When the tooth plate 4253 is pulled down to the top, the arc frame 4257b is completely closed, and the first limiting magnetic piece 4253a is fixed to the operating table 425 2. Magnetic attraction is used for fixed limiting. When the arc-shaped frame 4257b is closed, the linkage gear 4257e at the top is clamped on the clamping gear 4256b installed in the middle of the driving rod 4256. The clamping gear 4256b drives all the linkage gears 4257e, which drives the cutting blades 4257f on the linkage rod 4257d to rotate. The rotation directions of the two adjacent groups of cutting blades 4257f are opposite. The two adjacent groups of cutting blades 4257f come into contact and directly cut off the excess burrs.

[0089] The arc frame 4257b is unfolded to facilitate the threading of carbon nanowires. When closed, the burr removal mechanism 425 is in operation, and the driving motor 4255 drives the first transmission gear 4255a and the first transmission bevel gear 4255b to rotate. The first transmission gear 4255a drives the burr collecting gear 4258 to rotate. The driving guide rod 4258a installed in the burr collecting gear 4258 drives the collecting fan 4258b to rotate, and the removed burr tissue is collected and put into the collecting bag 4258c for collection.

[0090] According to the thickness and diameter of the finished nanowire, the corresponding adjustment hole 546 on the adjustment piece 545 is selected and passed through. When adjusting the tension of the nanowire, the outer rotating wheel 51 is rotated. When the rotation angle of the outer rotating wheel 51 is fixed, the handle 533 is pulled to insert the rod 532 away from the original clamping hole 52. After the angle of the outer rotating wheel 51 is rotated, the rod 532 is limited into the existing clamping hole 52 by the rebound force of the spring 535. The rotation of the outer rotating wheel 51 drives the connecting arm 542 on the first rotating ring 541 to move. The connecting arm 542 disengages from the second rotating ring 547 to complete the rotation, driving the six groups of adjustment pieces 545 to unfold synchronously. The nanowire set in the adjustment hole 546 can adjust its own tension according to the position of the adjustment piece 545, flexibly forming a tight or loose state. The nanowire also synchronously passes through the sleeve hole 624 and enters the first guide hole 731;

[0091] The control panel 101 and control button 102 on the control host 1 precisely control the extension and retraction of the electric telescopic rod 622. The insulating ring 623 on the electric telescopic rod 622 is immersed in the electrolyte tank 63. The electrolyte tank 63 contains electrolyte. The voltage released by the first electrode position 64 and the second electrode position 65 using the electrolyte as a medium electrochemically anneal the spun carbon nanowire composite electrode. During the electrochemical conversion of V2O3 to V2O5, the carbon nanowires act as a "protective structure" to effectively prevent the formation of by-products, thereby constructing a pea-pod-shaped nitrogen-doped carbon nanowire-coated amorphous V2O5 microsphere independent electrode material.

[0092] The electrochemically annealed nanowires continue to pass through the first guide hole 731 and the second guide hole 741 into the drying chamber 7. The heating wire 77 and the heating fan 78 in the drying hood 75 are turned on synchronously and work in conjunction with each other to form hot air that spreads around the drying hood 75 to quickly dry the carbon nanowires immersed in the electrolyte. The water vapor is discharged through the exhaust fan 72.

[0093] The dried nanowires pass through the wire hole 761 and fit on the upper limit of the wire roller 762. The collector is taken out and passed into the rotating rod 94. The collector is clamped and fixed on the collecting device 9 through the threaded connection between the positioning clamp 95 and the rotating rod 94. The six groups of collectors are installed together one by one. As the multiple groups of rotating rods 94 rotate, the nanowires are efficiently prepared and electrochemically annealed, and the treated carbon nanowire composite electrode is rolled up.

[0094] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.

The collected drum collector is installed in the rotating rod (94) and fixed by the positioning clamp (95). As the rotating rod (94) rotates, the nanowires are rolled up.
