Description

Technical Field

[0001] This utility model relates to the field of experimental equipment for battery preparation, and in particular to a small-scale preparation and pressure digital display test mold for all-solid-state batteries. Background Technology

[0002] All-solid-state batteries are considered one of the preferred next-generation battery technologies due to their high energy density and high safety (no risk of combustion from organic solvent leakage). During the development of all-solid-state batteries, achieving close contact between the electrode and electrolyte interface requires precise pressure control. The molding pressure (typically 10-500 MPa) directly affects the battery's ion transport efficiency and cycle life, placing higher demands on the fabrication and testing molds.

[0003] Existing equipment for the fabrication and testing of all-solid-state batteries has separate pressure monitoring: the pressure sensor needs to be installed outside the press, and the data is displayed through a separate instrument, resulting in bulky equipment and excessive space occupied on the workbench.

[0004] Therefore, it is necessary to provide a small-scale fabrication and pressure digital display testing mold for all-solid-state batteries to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a small-scale preparation and pressure digital display test mold for all-solid-state batteries, which has the advantage of small size and is easy to use and transport.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A small-scale fabrication and pressure digital display testing mold for all-solid-state batteries includes: a lower cover and an upper cover. A small pressure testing platform is mounted on the bottom of the lower cover. A battery forming mechanism is located between the lower and upper covers. The battery forming mechanism includes a PEEK pillar, a negative electrode pillar, a positive electrode pillar, and a sleeve. Mounting holes are formed on the PEEK pillar, and a display terminal is embedded in one side of the PEEK pillar. A sliding support pillar runs through the lower cover. A pressure detection component is mounted at the center of the top of the pressure testing platform and is connected to the display terminal.

[0008] Preferably, three screws are installed on the lower cover, and nuts are installed on the screws. The screws pass through the PEEK column and the upper cover.

[0009] Preferably, multiple screws are installed between the lower cover and the pressure testing platform.

[0010] Preferably, a clearance groove is provided at the bottom of the pressure testing platform.

[0011] Preferably, a connector is installed on the side of the PEEK column, and the connector is connected to the display terminal.

[0012] Preferably, insulating pads are installed at the bottom of the negative electrode post and at the top of the positive electrode post.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model sets a lower cover, a pressure detection platform and an upper cover, and sets a battery forming mechanism including a PEEK column, a negative electrode column, a positive electrode column and a sleeve, and integrates a display end on the PEEK column. It can display the battery pressure value through the display end during the preparation of all-solid-state batteries, making it more convenient to use. The overall structure of the device is smaller and more convenient to carry and transport.

[0015] (2) By opening an avoidance groove at the bottom of the pressure testing table, this utility model can facilitate the wiring arrangement of the pressure testing components.

[0016] (3) This utility model uses a plug-in interface installed on the side of the PEEK column. The modular quick-release interface facilitates the individual replacement of the pressure detection component or the display end, reducing maintenance costs.

[0017] (4) By installing insulating pads at the bottom of the negative terminal and the top of the positive terminal, this utility model can improve the insulation of the battery. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] Example 1:

[0026] like Figure 1-5As shown, this utility model provides a small-scale preparation and pressure digital display testing mold for all-solid-state batteries, comprising: a lower cover 1 and an upper cover 4, the lower cover 1 being connected to the upper cover 4. A small pressure testing platform 2 is installed at the bottom of the lower cover 1. A battery forming mechanism is provided between the lower cover 1 and the upper cover 4. The battery forming mechanism includes a PEEK column 3, a negative electrode column 5, a positive electrode column 6, and a sleeve 7. A mounting hole 15 is provided on the PEEK column 3, and a display end 16 is embedded in one side of it. The display end 16 is connected to the pressure testing platform 2 and is powered by an external circuit or by a battery inside the PEEK column 3. The charging port of the battery is located on the outer side of the PEEK column 3. A support column 11 is slidably installed on the lower cover 1, and the support column 11 penetrates the lower cover 1. A pressure detection component 12 is installed at the top center of the pressure testing platform 2. The pressure detection component 12 can detect pressure and is connected to the display end 16, which can display the pressure received by the pressure detection component 12. The display terminal 16 and pressure detection component 12 can use the existing structure and design of a separate pressure detector, which will not be described in detail here. In use, place the negative electrode post 5 on top of the support post 11 to support the bottom of the negative electrode post 5. Then, sequentially fit the sleeve 7 and PEEK post 3 onto the negative electrode post 5, so that the sleeve 7 is embedded in the mounting hole 15, and the negative electrode post 5 is partially embedded in the sleeve 7. Then, sequentially place the negative electrode material, electrolyte sheet, and positive electrode material into the sleeve 7 in the mounting hole 15. Install the positive electrode post 6 on top of the mounting hole 15, so that the negative electrode post 5 and the positive electrode post 6 are in contact with the negative electrode material and the positive electrode material, respectively. Cover the top of the positive electrode post 6 with the upper cover 4, connect the upper cover 4 to the lower cover 1, and then place the entire device on a press. The distance between the upper cover 4 and the lower cover 1 is adjusted by a press, thereby pressing the negative electrode post 5 and the positive electrode post 6 against the battery material. During the pressing process, the support post 11 is subjected to pressure drop, which in turn applies pressure to the pressure detection component 12. The pressure detection component 12 detects the pressure in real time and transmits the data to the display terminal 16 for real-time display. When the preset pressure value is reached, the distance between the upper cover 4 and the lower cover 1 is fixed, and then the battery can be tested. During the test, the positive electrode post 6 and the negative electrode post 5 are connected to the test device. The test process will not be described in detail here.

[0027] By setting up a lower cover 1, a pressure detection platform 2, and an upper cover 4, and setting up a battery forming mechanism including a PEEK column 3, a negative electrode column 5, a positive electrode column 6, and a sleeve 7, and integrating a display terminal 16 on the PEEK column 3, the battery pressure value can be displayed through the display terminal 16 during the preparation of the all-solid-state battery, making it more convenient to use. The overall structure of the device is smaller, making it easier to carry and transport.

[0028] Example 2:

[0029] like Figure 1-2As shown, three screws 8 are installed on the lower cover 1, and nuts 9 are installed on the screws 8. The structure and form of the nuts 9 are not limited. The screws 8 pass through the PEEK post 3 and the upper cover 4. In use, the screws 8 are passed through the PEEK post 3 and the upper cover 4 to connect the upper cover 4 and the lower cover 1. After the battery pressure is reached, the nuts 9 are tightened to fix the battery pressure. Then the pressure head of the press is raised, the device is removed, and subsequent battery testing can be performed.

[0030] By setting screw 8 and nut 9, the lower cover 1 and upper cover 4 can be easily connected.

[0031] Example 3:

[0032] like Figure 4 As shown, multiple screws 13 are installed on the lower cover 1, and the bottom end of the screws 13 is threadedly connected to the pressure testing platform 2, thereby fixing the lower cover 1 to the pressure testing platform 2.

[0033] By installing multiple screws 13 on the lower cover 1, the lower cover 1 can be easily fixedly connected to the pressure testing platform 2.

[0034] Example 4:

[0035] like Figure 3 As shown, a clearance groove 14 is provided at the bottom of the pressure testing platform 2, through which the wiring of the pressure testing component 12 can pass and connect to the display terminal 16.

[0036] By opening a clearance groove 14 at the bottom of the pressure testing platform 2, the wiring arrangement of the pressure testing component 12 can be facilitated.

[0037] Example 5:

[0038] like Figure 5 As shown, an interface 17 is installed on the side of the PEEK column 3. The interface 17 is connected to the display terminal 16. One end of the connecting wire of the pressure detection component 12 is plugged into the interface 17, so that the pressure detection component 12 can be connected to the display terminal 16. This connection can be easily disconnected, making it convenient to replace the pressure detection component 12 or the display terminal 16 separately.

[0039] By installing the plug interface 17 on the side of the PEEK column 3, a modular quick-release interface is installed, which facilitates the individual replacement of the pressure detection component 12 or the display end 16, reducing maintenance costs.

[0040] Example 6:

[0041] like Figure 2 As shown, an insulating pad 10 is installed at the bottom of the negative terminal 5 and the top of the positive terminal 6. The insulating pad 10 enables the positive terminal 6 and the negative terminal 5 to be insulated from the lower cover 1 and the upper cover 4, thus preventing leakage.

[0042] Installing insulating pads 10 at the bottom of the negative terminal 5 and the top of the positive terminal 6 can improve the insulation of the battery.

[0043] Example 7:

[0044] The display screen used in the display unit 16 is an OLED digital display screen, which can simultaneously display the pressure-time curve and peak data. This design makes it easy to grasp the changing pattern of battery pressure.

[0045] Working principle: In use, place the negative electrode post 5 on top of the support post 11 to support the bottom of the negative electrode post 5. Then, put the sleeve 7 and the PEEK post 3 onto the negative electrode post 5 in sequence, so that the sleeve 7 is embedded in the mounting hole 15 and the negative electrode post 5 is partially embedded in the sleeve 7. Then, put the negative electrode material, electrolyte sheet and positive electrode material into the sleeve 7 in the mounting hole 15 in sequence. Install the positive electrode post 6 on top of the mounting hole 15, so that the negative electrode post 5 and the positive electrode post 6 are in contact with the negative electrode material and the positive electrode material respectively. Cover the top of the positive electrode post 6 with the upper cover 4 and connect the upper cover 4 to the lower cover 1. Then place the entire device under pressure. On the machine, the distance between the upper cover 4 and the lower cover 1 is adjusted by the press, thereby pressing the negative terminal 5 and the positive terminal 6 against the battery material. During the pressing process, the support column 11 is subjected to pressure drop, which in turn applies pressure to the pressure detection component 12. The pressure detection component 12 detects the pressure in real time and transmits the data to the display terminal 16 for real-time display. When the preset pressure value is reached, the distance between the upper cover 4 and the lower cover 1 is fixed, and then the battery can be tested. During the test, the positive terminal 6 and the negative terminal 5 are connected to the test device. The test process will not be described in detail here.
