Description

Technical Field

[0001] The invention relates to the technical field of nanomaterials, and in particular to a device for preparing a transition metal sulfide positive electrode material. Background Art

[0002] With the development of social economy, the intensification of energy crisis and the increasing environmental pollution, the development concept advocated by the scientific community of making full use of resources and energy and minimizing environmental load has been deeply rooted in the hearts of the people. Zinc-ion batteries are favored by more and more scientific researchers because of their rich resource reserves and the use of safe aqueous electrolytes. The energy storage mechanism of zinc-ion batteries is similar to that of lithium-ion batteries, both of which are based on the "rocking chair" reversible reaction of alkali metal ions between the positive and negative electrodes. However, Zn 2+ The high polarity leads to the obstruction of the reversible insertion and extraction process in the positive electrode material, slow diffusion rate and material structure collapse during cyclic charge and discharge, which seriously restricts the commercialization process of zinc-ion batteries. Therefore, how to design and prepare high energy density and long-term support Zn 2+ Reversible deintercalation electrode materials, especially positive electrode materials, are the key to solving the development bottleneck of rechargeable zinc batteries.

[0003] Hollow structure materials are considered to be promising candidate materials for energy storage and conversion system applications due to their large specific surface area, multiple active sites and low density. Their unique structure increases the active contact area between active materials and electrolyte solutions and reduces the transmission path of electrolyte ions in the active material system, greatly improving the performance of the materials. Using the template method, hollow materials constructed of two-dimensional transition metal disulfide nanosheets can be effectively prepared.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention. Example 1

[0037] A transition metal chalcogenide positive electrode material preparation device, such as Figure 1-Figure 8As shown, it includes a reactor 1, a lid 2, a feeding assembly, a hydrothermal assembly, a limiting ring 10, a discharge barrel 11, a stirring mechanism 12 and a filtering mechanism 13. The upper part of the reactor 1 is connected to a detachable lid 2, and a feeding assembly is arranged on the lid 2, and different chemical raw materials can be added to the feeding assembly. The reactor 1 is provided with a hydrothermal assembly, and the hydrothermal assembly can perform a hydrothermal reaction on the chemical raw materials. A limiting ring 10 is welded on the inner top wall of the lid 2, and the discharge barrel 11 is placed in the limiting ring 10. A stirring mechanism 12 is arranged in the reactor 1, and the stirring mechanism 12 can accelerate the reaction of the chemical raw materials. A filtering mechanism 13 is arranged between the feeding assembly and the reactor 1, and the filtering mechanism 13 can filter large particles of chemical raw materials.

[0038] like Figure 1-Figure 3 As shown, the material discharge assembly includes a first material discharge barrel 3, a transparent plate 4 and a second material discharge barrel 5. The front and rear parts of the cover 2 are connected to the first material discharge barrel 3, and the first material discharge barrel 3 can add sodium molybdate and L-cysteine. The left part of the cover 2 is connected to the second material discharge barrel 5, and the second material discharge barrel 5 can add alkali. The lower part of the second material discharge barrel 5 extends into the middle position of the cover 2, and the front sides of the second material discharge barrel 5 and the first material discharge barrel 3 are connected to the transparent plate 4.

[0039] like Figure 1-Figure 3 As shown, the hydrothermal component includes a hot water pressurizer 6, a ball valve 7, a connecting pipe 8 and a drain valve 9. The hot water pressurizer 6 is installed on the left side of the reactor 1 by bolts, and the ball valve 7 is installed on the upper part of the hot water pressurizer 6. The upper part of the hot water pressurizer 6 is connected to a connecting pipe 8, and the tail end of the connecting pipe 8 is connected to the cover 2. The lower part of the right side of the reactor 1 is connected to the drain valve 9.

[0040] The device prepares the required nanomaterials through the template method. When using the device, the staff will open the lid 2 and put the SiO2 nanosphere template into the discharge barrel 11. After the SiO2 nanosphere template is placed, the staff will close the lid 2. At this time, the discharge barrel 11 drives the SiO2 nanosphere template into the reactor 1, and then the staff will put sodium molybdate and L-cysteine ​​into the reactor 1 through the two first discharge barrels 3 respectively. At this time, the staff will open the ball valve 7, and the water with a certain temperature and pressure in the hot water pressurizer 6 will enter the reactor 1 through the connecting pipe 8. After the high-temperature and high-pressure water enters the reactor 1, the staff will close the ball valve 7, and the high-temperature and high-pressure water will hydrothermally react the SiO2 nanosphere template and the monomer of the transition metal sulfide, so that MoS2 nanosheets can be wrapped on the surface of the SiO2 nanosphere template, and then the alkali will be directly introduced into the discharge barrel 11 through the second discharge barrel 5. The SiO2 template can be removed by the alkali to obtain the second 2-dimensional hollow MoS2 balls. When the first discharge barrel 3 adds sodium molybdate and L-cysteine ​​to the reactor 1, the filtering mechanism 13 can filter large particles of matter, so that fine particles enter the reactor 1, which is convenient for mixing reaction. During the reaction of the substances in the reactor 1, the fluid in the reactor 1 can be stirred by the stirring mechanism 12 to accelerate the reaction time. When the two-dimensional hollow MoS2 balls are manufactured, the staff discharges the fluid in the reactor 1 through the drain valve 9, and then the staff opens the lid 2 again. After the lid 2 is opened, the discharge barrel 11 is raised through the limit ring 10. At this time, the staff can remove the discharge barrel 11 from the limit ring 10 to take the two-dimensional hollow MoS2 balls in the discharge barrel 11. After the two-dimensional hollow MoS2 balls are taken, the staff puts the discharge barrel 11 back on the limit ring 10, and then puts the lid 2 back on the reactor 1, so that the limit ring 10 drives the discharge barrel 11 into the reactor 1.

[0041] like Figure 2 , Figure 4 and Figure 5 As shown, the stirring mechanism 12 includes a servo motor 120, a rotating ring 121, a stirring rod 122, a spur gear 123 and a pinion 124. The servo motor 120 is bolted to the bottom of the reactor 1, and the servo motor 120 can provide power for stirring. The output shaft of the servo motor 120 penetrates into the reactor 1 and is rotatably connected to the reactor 1. The upper part of the output shaft of the servo motor 120 is connected to the rotating ring 121, and the middle part of the rotating ring 121 is embedded in the discharge barrel 11. Three stirring rods 122 are rotatably connected to the bottom of the reactor 1. The lower part of the output shaft of the servo motor 120 is keyed to the spur gear 123, and the lower part of the stirring rod 122 is keyed to the pinion 124, and the pinion 124 is meshed with the spur gear 123.

[0042] When using the device, the staff starts the servo motor 120, and the output shaft of the servo motor 120 rotates to drive the swivel 121 to rotate, and the rotation of the swivel 121 drives the discharge barrel 11 to rotate. The output shaft of the servo motor 120 rotates and drives the spur gear 123 to rotate. The rotation of the spur gear 123 drives the pinion 124 to rotate. The rotation of the pinion 124 drives the stirring rod 122 to rotate. The rotation of the stirring rod 122 can stir the fluid in the reactor 1 to accelerate the reaction time and improve the preparation efficiency. When the device is used, the staff turns off the servo motor 120.

[0043] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the filtering mechanism 13 includes a rotating ring 130, a guide rod 131, a sleeve 132, a return spring 133, a twisted rod 134, a second filter plate 135 and a first filter plate 136. The rotating ring 130 is connected to the upper side of the rotating ring 121. The guide rods 131 are welded on both the front and rear sides of the upper inner part of the cover 2. The guide rods 131 are slidably connected to the sleeves 132. The lower ends of the sleeves 132 are in contact with the rotating ring 130. The return springs 133 are connected between the sleeves 132 and the adjacent guide rods 131. The two twisted rods 134 are welded to the upper and rear sides of the cover 2. The twisted rods 134 are all sleeved on the upper part of the sleeve 132, and the lower part of the twisted rods 134 is provided with a threaded groove, which cooperates with the sleeve 132. The upper part of the twisted rods 134 is inserted into the adjacent first discharge barrel 3, and the upper end of the twisted rods 134 is connected to the second filter plate 135, and the second filter plate 135 is located in the first discharge barrel 3. The middle position of the first discharge barrel 3 is connected to the first filter plate 136, which can filter large particles of chemical raw materials, and the second filter plate 135 is rotatably connected to the adjacent first filter plate 136.

[0044] When using the device, the rotation of the rotating ring 121 drives the rotating ring 130 to rotate. During the rotation of the rotating ring 130, the sleeve 132 will be squeezed to slide upward on the guide rod 131, and the reset spring 133 will be deformed. When the recessed part of the rotating ring 130 rotates to cooperate with the sleeve 132, under the action of the reset spring 133, the sleeve 132 slides downward and resets. During the up and down sliding process, the sleeve 132 will cooperate with the threaded groove, thereby squeezing the twisted rod 134 to continuously perform forward and reverse rotation. The rotation of the twisted rod 134 drives the second filter plate 135 to rotate. When the staff puts sodium molybdate or L-cysteine ​​into the first discharge barrel 3, the first filter plate 136 can filter large particles, and the rotating second filter plate 135 can move relative to the first filter plate 136 to avoid clogging of the first filter plate 136. Example 2

[0045] On the basis of Example 1, Figure 2 and Fig. 9As shown, it also includes an anti-blocking mechanism 14, which can prevent chemical raw materials from being blocked. The anti-blocking mechanism 14 includes a first rotating paddle 140 and a second rotating paddle 141. The upper key of the twisted rod 134 is connected to the first rotating paddle 140, and the first rotating paddle 140 is located in the lower part of the first discharge barrel 3. The second rotating paddle 141 is welded on the upper side of the second filter plate 135, and the second rotating paddle 141 is located above the first filter plate 136.

[0046] When the device is used, the rotation of the twisted rod 134 will drive the first rotating paddle 140 to rotate. The rotation of the first rotating paddle 140 can move the chemical raw materials in the lower part of the first discharge barrel 3 to prevent the chemical raw materials from being blocked at the outlet. The rotation of the second filter plate 135 can drive the second rotating paddle 141 to rotate. The rotation of the second rotating paddle 141 can move the chemical raw materials above the first filter plate 136 to speed up the speed at which the chemical raw materials pass through the first filter plate 136.

[0047] like Figure 1 , Figure 2 and Fig.10 As shown, it also includes a vacuum mechanism 15, which can extract the gas generated during the reaction. The vacuum mechanism 15 includes a vacuum pump 150, a vacuum pipe 151 and an exhaust pipe 152. The vacuum pump 150 is installed on the upper right side of the reactor 1 by bolts, the vacuum pipe 151 is connected between the upper side of the vacuum pump 150 and the upper right side of the reactor 1, and the exhaust pipe 152 is connected to the upper part of the vacuum pump 150.

[0048] When using the device, the staff connects an external pipeline to the exhaust pipe 152. During the reaction, a large amount of gas will be generated. After the hydrothermal reaction, the staff can start the vacuum pump 150. The vacuum pump 150 operates to extract the gas in the reactor 1 through the vacuum pipe 151, and then discharges the gas through the exhaust pipe 152. After the vacuuming is completed, the staff turns off the vacuum pump 150 and then adds alkali to the reactor 1 to reduce the contact reaction between the alkali and the air, which leads to reduced concentration or agglomeration.

[0049] like Figure 1 , Fig.11 and Fig.12 As shown, it also includes a cover opening mechanism 16, which can automatically open the cover 2. The cover opening mechanism 16 includes a connecting ring 160, a support frame 161 and an electric push rod 162. The lower part of the cover 2 is connected to the connecting ring 160, and the support frames 161 are installed on the front and rear sides of the reactor 1 by bolts. The support frames 161 are connected to the electric push rods 162, and the upper ends of the electric push rods 162 are connected to the connecting ring 160.

[0050] When it is necessary to open the lid 2, the staff controls the electric push rod 162 to extend, and the extension of the electric push rod 162 drives the connecting ring 160 to move upward, and the upward movement of the connecting ring 160 drives the lid 2 to move upward and open. When it is necessary to close the lid 2, the staff controls the electric push rod 162 to shorten, and the shortening of the electric push rod 162 drives the connecting ring 160 to move downward, and the downward movement of the connecting ring 160 drives the lid 2 to move downward and close. In this way, the purpose of automatically opening and closing the lid 2 can be achieved.

[0051] like Figure 1 , Figure 2 , Fig.13 and Fig.14 As shown, it also includes a timing mechanism 17, which can count time to remind staff. The timing mechanism 17 includes a timer 170 and a warning light 171. The timer 170 is installed at the lower right side of the reactor 1 and is located above the drain valve 9 by bolts. The top of the timer 170 is connected to the warning light 171.

[0052] When using the device, the staff can measure the reaction time through the timer 170. When the preset time is reached, the warning light 171 flashes to remind the staff to prevent the staff from forgetting the time, reduce mistakes and improve the success rate.
