Description

Technical Field

[0001] This invention relates to the field of battery technology, and more specifically, to an electrolyte insulating layer, its production equipment, and its preparation process required in the manufacture of electrolytes for all-solid-state physical batteries. Background Technology

[0002] With the continuous advancement of modern science and technology, while greatly satisfying people's material and spiritual needs, low-carbon, energy-saving, and emission-reduction are the best choices for a sustainable economic development model.

[0003] In the field of battery technology, all-solid-state batteries, with their long lifespan, fast charging speed, high energy density, and wide temperature range, represent the future direction of battery technology. The electrolyte insulation layer preparation process involved in this invention is one of the core technologies required for the polarization process of the electrolyte in an all-solid-state physical battery.

[0004] The electrolyte insulating layer made of existing dielectric materials has low polarizability, which directly results in the inability to effectively improve the polarizability of the electrolyte required for the aforementioned all-solid-state physical batteries.

[0005] To meet this technical requirement, this invention provides a process for preparing the electrolyte insulating layer, thereby addressing the shortcomings of existing electrolyte insulating layer materials required for all-solid-state physical storage battery technology. Summary of the Invention

[0006] This invention aims to provide an electrolyte insulating layer required for the fabrication of all-solid-state batteries. This electrolyte insulating layer effectively solves the problem of low polarizability of traditional electrolyte insulating layers, which cannot effectively meet the polarization requirements of the electrolyte in all-solid-state batteries. All-solid-state batteries fabricated using the electrolyte insulating layer of this invention can effectively improve the polarizability of the battery electrolyte, thereby more effectively increasing the energy storage per unit volume of the battery. Simultaneously, this invention also provides a preparation process for the electrolyte insulating layer, as well as dedicated production equipment for the preparation process.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0008] A production apparatus for an electrolyte insulating layer in an all-solid-state battery is characterized in that it includes a heating element, an electrolyte, and a dielectric, as well as a DC voltage positive electrode plate and a DC voltage negative electrode plate; wherein,

[0009] The heating element is placed at the bottom of the device to heat the electrolyte and melt it.

[0010] The dielectric is located above the electrolyte to prevent the electrolyte current from conducting, and at the same time, it completes the polarization of the electrolyte under the combined action of heating and applying DC voltage.

[0011] The electrolyte is placed in the electrolyte chamber to prevent leakage from the bottom when the electrolyte is in liquid state. The bottom of the electrolyte chamber is in full contact with the DC voltage negative plate. The electrolyte liquid must be in full contact with the dielectric, but the electrolyte liquid level is not higher than the upper surface of the dielectric.

[0012] The DC voltage positive plate and DC voltage negative plate are used to apply a DC voltage to the electrolyte to polarize it.

[0013] A process for preparing an electrolyte insulating layer for all-solid-state physical batteries, characterized by including the following polarization treatment process:

[0014] While heating the electrolyte, an external DC voltage is applied. Once the electrolyte changes from a solid to a liquid state and is fully polarized, it is rapidly cooled to room temperature, and the applied DC voltage is stopped, thus completing the polarization of the electrolyte.

[0015] The polarization process is repeated multiple times;

[0016] The electrolyte used in each polarization process is different;

[0017] The electrolyte obtained from the previous polarization treatment is used as a dielectric in the subsequent polarization treatment process.

[0018] During each polarization process, the melting point of the dielectric should be higher than that of the electrolyte, and the negative temperature point of the dielectric should be higher than that of the electrolyte.

[0019] An electrolyte insulating layer for all-solid-state physical batteries, characterized by the following features:

[0020] The above polarization process is repeated multiple times, and the final electrolyte obtained is the electrolyte insulating layer.

[0021] The electrolyte insulating layer produced by the equipment and process of this invention is the electrolyte insulating layer required in the manufacturing process of the all-solid-state physical storage battery mentioned in this invention. The electrolyte insulating layer produced by the equipment and process of this invention can also be called dielectric. After multiple polarization treatments, the polarizability is effectively improved. When the electrolyte insulating layer is used to polarize the electrolyte required for the all-solid-state physical storage battery, under the action of DC voltage, the electrolyte polarizability is effectively improved, and its rapid rise time of polarizability is also effectively advanced. That is, under the same DC voltage, the electrolyte polarizability is effectively improved.

[0022] To ensure sufficient polarization of the electrolyte insulating layer, this invention utilizes the characteristics that different electrolytes and dielectrics have different melting points and negative temperature points. Through repeated polarization processes of the electrolyte and dielectric, the electrolyte insulating layer required for the all-solid-state physical battery mentioned in this invention is obtained. After each polarization process, the electrolyte is used as the dielectric for the next polarization process, and the electrolyte after the last polarization process is used as the electrolyte insulating layer required for the all-solid-state physical battery mentioned in this invention.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] This embodiment discloses an appendix Figure 1The equipment shown is for producing an electrolyte insulating layer. The equipment comprises a heating element 13, a DC voltage positive plate 14, a DC voltage negative plate 15, a dielectric 30, and an electrolyte 31. The heating element 13 heats the electrolyte 31. The DC voltage provided by the DC voltage positive plate 14 and the DC voltage negative plate 15 applies a polarization voltage to the electrolyte 31 and the dielectric 30. The electrolyte 31 is placed inside an electrolyte chamber 32 to prevent leakage from the bottom when in a liquid state. The bottom of the electrolyte chamber 32 is in full contact with the DC voltage negative plate 15, and the liquid electrolyte is in full contact with the dielectric 30, but the electrolyte level is not higher than the upper surface of the dielectric.

[0033] Example 2

[0034] This embodiment discloses a process for preparing an electrolyte insulating layer, the process flow of which is as follows: Figure 2 As shown, from the appendix Figure 2 As can be seen, the formation of the electrolyte insulating layer is accomplished through four polarization processes. The following describes each polarization process in turn:

[0035] First polarization treatment: The first electrolyte 31a is heated by the heating element 13, and a DC voltage is applied to the first dielectric 30a and the first electrolyte 31a through the DC voltage positive plate 14 and the DC voltage negative plate 15. The first electrolyte 31a gradually changes from solid to liquid. After the first electrolyte 31a is effectively polarized, the temperature of the heating element 13 is rapidly reduced while the DC voltage is continuously applied until it reaches room temperature. The DC voltage applied by the DC voltage positive plate 14 and the DC voltage negative plate 15 is turned off. The cooled first electrolyte 31a has returned to solid state, but it still retains polarity. After its size and thickness are adjusted, it is used as the second dielectric 30b in the second polarization treatment.

[0036] Second polarization treatment: The second electrolyte 31b is heated by the heating element 13, while a DC voltage is applied to the second dielectric 30b and the second electrolyte 31b through the DC voltage positive plate 14 and the DC voltage negative plate 15. The second electrolyte 31b gradually changes from solid to liquid. After the second electrolyte 31b is effectively polarized, the temperature of the heating element 13 is rapidly reduced while the DC voltage is continuously applied until it reaches room temperature. The DC voltage applied by the DC voltage positive plate 14 and the DC voltage negative plate 15 is turned off. The cooled second electrolyte 31b has returned to solid state, but it still retains polarity. After its size and thickness are adjusted, it is used as the third dielectric 30c in the third polarization treatment process.

[0037] Third polarization treatment: The third electrolyte 31c is heated by the heating element 13, and a DC voltage is applied to the third dielectric 30c and the third electrolyte 31c through the DC voltage positive plate 14 and the DC voltage negative plate 15. The third electrolyte 31c gradually changes from solid to liquid. After the third electrolyte 31c is effectively polarized, the temperature of the heating element 13 is rapidly reduced while the DC voltage is continuously applied until the room temperature is reached. The DC voltage applied by the DC voltage positive plate 14 and the DC voltage negative plate 15 is turned off. The cooled third electrolyte 31c has returned to solid state, but it still retains polarity. After its size and thickness are processed, it is used as the fourth dielectric 30d in the fourth polarization treatment process.

[0038] The fourth polarization process: The fourth electrolyte 31d is heated by the heating element 13, while the fourth dielectric 30d and the fourth electrolyte 31d are subjected to DC voltage through the DC voltage positive plate 14 and the DC voltage negative plate 15. The fourth electrolyte 31d gradually changes from solid to liquid. After the fourth electrolyte 31d is effectively polarized, the temperature of the heating element 13 is rapidly reduced while the DC voltage is continuously applied until it reaches room temperature. The DC voltage applied by the DC voltage positive plate 14 and the DC voltage negative plate 15 is turned off. The cooled fourth electrolyte 31d has returned to solid state, but it still retains polarity. After adjusting its size and thickness, the final electrolyte insulating layer 6 is obtained. The electrolyte insulating layer 6 is the electrolyte insulating layer required for the fabrication of the all-solid-state physical battery mentioned in this invention. This completes the entire preparation process of the electrolyte insulating layer.

[0039] To better illustrate the process of this invention, a schematic diagram of polar molecules and positive and negative ions is used. Figure 3 Schematic diagram of electrolyte and dielectric before polarization Figure 4 Magnified schematic diagram of the polarization process of electrolyte and dielectric Figure 5 The above implementation process will be further described in detail below:

[0040] Diagram of polar molecules and positive and negative ions Figure 3 In this process, both electrolytes and dielectrics must be polar molecules. Nonpolar molecules, whether electrolytes or dielectrics, cannot be polarized, so nonpolar molecules cannot be selected. Polar molecules are composed of polar positive ions 25 and polar negative ions 26, which are connected together by positive and negative ion bonding bonds 27.

[0041] Schematic diagram of the pre-polarization states of electrolytes and dielectrics Figure 4 As can be seen, the dielectric in the pre-polarized dielectric polar state 28, which consists of countless dielectric molecules, and the electrolyte in the pre-polarized electrolyte polar state 29, which consists of countless electrolyte molecules, are both in a disordered state, and neither of them exhibits polarity as a whole.

[0042] A magnified schematic of the polarization process of electrolytes and dielectrics. Figure 5 As can be seen, the manufacturing process of the electrolyte insulating layer 6 is completed through multiple polarization processes. Through the continuous change of the functional roles of the dielectric and the electrolyte, the polarizability of the electrolyte is further improved with each polarization process. The number of polarization processes is not fixed, but is determined by the different material properties used, based on the polarizability required by the electrolyte. The electrolyte obtained from the last polarization process is also the last role conversion between the electrolyte and the dielectric, thus obtaining the electrolyte insulating layer 6 required in the manufacturing process of the all-solid-state physical battery electrolyte mentioned in this invention.

[0043] The electrolyte insulating layer produced by the above-described embodiment is used as the electrolyte insulating layer required for the all-solid-state physical battery mentioned in this invention. It is actually a type of dielectric material that has been pre-polarized. When using it to produce the electrolyte, the electrolyte polarizability can be effectively improved. At the same time, under the same applied DC voltage value, the rising edge of the electrolyte's rapid polarizability arrives earlier. This not only effectively improves the electrolyte's polarizability but also more effectively ensures its safety during the production process.

[0044] Through the above implementation process, it can also be seen that the melting point and negative temperature point of the electrolyte used in each process are lower than those of the dielectric in that process.

[0045] The above-described implementation methods are merely preferred embodiments of the present invention and are not intended to define the scope of the present invention. Without departing from the design and inventive spirit of the present invention, various modifications and alterations made by those skilled in the art to the technical solutions of the present invention in related applicable fields are all within the scope of protection defined in the claims of the present invention.

[0046] As described in the process of the electrolyte insulating layer of the present invention, the electrolyte is polarized multiple times. This does not represent a specific number of times, but only illustrates the preparation process of the electrolyte insulating layer. The specific number of times is determined by the characteristics of the electrolyte and dielectric materials used.

[0047] Regarding the above implementation method, it should be specifically pointed out that it is a production equipment and preparation process technology for the electrolyte insulating layer required for an all-solid-state physical battery. It is an important component of the technology required for an all-solid-state physical battery described in this invention, and represents a different focus of the all-solid-state physical battery.
