Description

Technical Field

[0001] The utility model relates to the technical field of sodium metal button half-cell sodium sheet processing devices, in particular to a handheld sodium metal button half-cell sodium sheet processing device, and specifically to a production device for an ultra-thin sodium metal strip. Background Art

[0002] Sodium is abundant on Earth, and room temperature sodium-ion batteries have surpassed lithium-ion batteries to become energy storage devices with great development potential. Similar to lithium metal anodes in lithium batteries, metallic sodium anodes are considered to be ideal rechargeable battery anode materials due to their low cost, high theoretical specific capacity, and high natural abundance. However, due to the large ionic radius, the slow kinetics of Na+ ions limits the migration efficiency of ions. The use of metallic sodium anodes in sodium metal batteries has been hampered by a series of fundamental challenges, including the formation of unstable SEI (full name solid electrolyte interface), the growth of Na dendrites, and large volume expansion. These challenges have hindered the development of sodium metal batteries.

[0003] The production of the negative electrode sodium sheet of the metal sodium battery is complicated. The sodium is usually preserved by soaking large sodium ingots in kerosene and sealing them in tin cans. When the sodium ingot is used, it needs to be moved to the glove box first. After taking out the sodium ingot from the glove box, it is rolled into a sodium sheet with uniform thickness with a rolling pin, and a round shot of the corresponding diameter is used to punch out the sodium sheet to obtain the metal sodium electrode of the button sodium battery.

[0004] Metallic sodium is a highly reactive metal with extremely active chemical properties and soft texture. Currently, there is no mature sodium sheet processing technology, and there are no commercial sodium sheets available for direct use. Due to the lack of professional processing tools or equipment, the flatness and smoothness of the produced sodium sheets are generally poor, and the thickness is also uneven, which has a great impact on the qualified rate of battery assembly, the evaluation of electrode materials, and the timeliness of experiments. Therefore, it is urgent to develop a production device for ultra-thin metallic sodium strips to produce sodium sheets. Utility Model Content

One end of the support shaft 2113 passes through the first axial hole on the box connecting plate 2110 and is fixedly connected to the upper surface of the elastic support bottom plate 219. The other end of the support shaft 2113 passes through the second axial hole on the sleeve end cover. The support shaft 2113 is provided with a shoulder at one end close to the box connecting plate 2110. The diameter of the first axial hole is smaller than the diameter of the shoulder. A spring 2114 is sleeved on the support shaft 2113. One end of the spring 2114 abuts against the shoulder, and the other end of the spring 2114 abuts against the sleeve end cover. With such a configuration, the device adopts a segmented pressing method during the sodium metal pressing process. First, the sodium ingot is pressed into a strip shape by the primary rolling mechanism 21; and then the strip sodium metal is pressed into an ultra-thin strip shape by the secondary rolling mechanism 22. Since the sodium metal is in the form of a thick sodium ingot before processing, the device connects two elastic support components to the upper and lower ends of the two primary roller units in each group of primary roller assemblies. When the sodium ingot contacts the rollers of the two primary roller units, the spring 2114 in the elastic support unit is compressed. However, due to the support force of the spring, the sodium ingot can smoothly enter the upper and lower rollers and can be pressed at the same time. Since the metallic sodium has been pressed into a strip shape by the primary roller mechanism 21 before entering the secondary roller mechanism 22, the uniformity of the pressing of the sodium metal can be improved when entering the secondary roller mechanism 22. In addition, the inner sleeve 2111 and the outer sleeve 2112 of the device are connected by threads, so that the initial support force of the spring 2114 can be adjusted. Other components and connection relationships are the same as those of the first or second specific implementation.

[0036] Specific implementation method four: Combination Figures 1 to 10 The present embodiment is described. Each secondary roller unit of the present embodiment includes a secondary roller body 221 and a U-shaped secondary roller support 222. Two side wing plates of the U-shaped secondary roller support 222 are provided with two coaxially arranged second shaft holes, and two second bearings are coaxially embedded in the two second shaft holes. The opening of the U-shaped secondary roller support 222 is provided with a parallelly arranged secondary roller body 221, and the two ends of the core shaft of the secondary roller body 221 are respectively connected to the two second bearings; each secondary chain transmission mechanism includes a secondary roller driving motor 223, a secondary active sprocket, a second The secondary roller drive motor 223 is mounted on the middle web of the U-shaped secondary roller support 222. The secondary roller drive motor 223 is mounted on the end of the rotating shaft of the secondary roller drive motor 223. A secondary driving sprocket is mounted on one end of the mandrel of one secondary roller body 221. The secondary driven sprocket is connected to the secondary driving sprocket through the first and second transmission chains. A secondary transmission sprocket is mounted on one end of the mandrel of each secondary roller body 221. All secondary transmission sprockets are connected through the second and second transmission chains. In this way, each group of secondary roller assemblies includes two upper and lower secondary roller units. The primary roller mechanism 21 presses the metallic sodium into a strip shape, and then the strip metallic sodium is pressed into an ultra-thin strip shape through the secondary roller mechanism 22. The secondary chain transmission mechanism is used to drive the secondary roller body 221 to rotate. The secondary roller drive motor 223 reduces the rotation speed through the secondary driving sprocket, the secondary driven sprocket and the first and second transmission chains, and drives the roller to rotate at an appropriate speed. The second secondary transmission chain and multiple secondary transmission sprockets transmit power from the secondary roller drive motor 223 to the rollers to ensure synchronous rotation of the rollers. The high-precision rollers and transmission system ensure that the thickness of the metallic sodium strip is uniform and the surface is smooth.

With such a configuration, the difference between the rigid support assembly and the elastic support assembly is that the secondary rolling mechanism 22 is the last process in the sodium metal pressing process, and the processing requirements of the sodium metal need to be guaranteed, so it is necessary to ensure that the gap between the upper and lower rollers in the secondary rolling mechanism 22 is consistent with the thickness requirements of the processed sodium metal. In addition, the gap between the upper and lower rollers in the rigid support unit of the device can be adjusted by screwing the long support bolt 2211 into the depth, so as to adapt to the pressing of metallic sodium with different thickness requirements.

When the two nuts of the bidirectional screw mechanism 2332 are moved to the specified position, the clamping motor 2334 is paused. Then, after the operator takes out the sodium ingot from the glove box with the help of gloves, the sodium ingot is placed on the upper surface of the rectangular support block of the left clamping jaw 2336 and the right clamping jaw 2337. Finally, the clamping motor 2334 is started again to drive the bidirectional screw mechanism 2332 to rotate until the left clamping jaw 2336 and the right clamping jaw 2337 clamp the sodium ingot, and at this time the sodium ingot is located in the middle of the roller.
