[0035] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0038] Figure 1 A schematic diagram of the electrolyte structure of a lithium iron phosphate or ternary lithium battery in the prior art, provided for embodiments of this application.
[0039] Figure 2 This is a schematic diagram of the electrolyte structure of a solid lithium battery provided in an embodiment of this application.
[0040] like Figure 1 As shown, the battery cells in existing portable energy storage power supplies consist of a graphite negative electrode, a solid electrolyte, and a positive electrode.
[0041] The inventors discovered the advantages of solid-state lithium batteries, such as high energy density and safety, while researching energy storage power sources. Figure 2 As shown, a solid-state lithium battery includes a lithium metal anode and a solid electrolyte uniformly distributed within the cathode material. After comparison, it was found that... Figure 1 and Figure 2 It is known that lithium iron phosphate or ternary lithium batteries have relatively low energy density, resulting in larger cell footprints in energy storage devices. This leads to heavier devices, slower charging speeds, lower safety, and flammability / explosion risks, negatively impacting user experience. In contrast, solid-state lithium batteries, with their high energy density and safety advantages, can reduce overall device weight, making them more portable, and offer faster charging speeds and greater safety and reliability, significantly improving the user experience.
[0042] To address the aforementioned technical problems, this application provides the following technical concept: The biggest difference between solid-state batteries and ordinary batteries lies in the form of the electrolyte. Solid-state batteries upgrade all or part of the electrolyte to a solid electrolyte, thereby achieving higher energy density and safety stability. Energy density exceeds 1000Wh / L. Using lithium metal as the negative electrode can increase the battery's energy storage capacity by 2 to 3 times compared to current silicon-oxygen material negative electrodes. Due to the lithium plating phenomenon of lithium metal, only the inorganic separator of solid-state batteries can prevent lithium dendrite penetration, avoid short circuits, and improve safety and stability.
[0043] Figure 3 This is a schematic diagram of a nail penetration test for a solid lithium battery provided in an embodiment of this application.
[0044] Based on the above technical concept, the inventors also conducted a nail penetration test on a solid-state lithium battery. For example... Figure 3 As shown, after the needle passes through the positive electrode material of the solid-state lithium battery, and then sequentially through the solid electrolyte, the second positive electrode material, the separator, the negative electrode, and the aluminum foil, the solid-state lithium battery remains in a safe state. This demonstrates high safety performance.
[0045] The specific structure and implementation principle of a portable energy storage power supply provided in this application will be described below with reference to the accompanying drawings and specific embodiments.
[0046] Figure 4 This is a schematic diagram of the overall structure of the portable energy storage power supply provided in the embodiments of this application.
[0047] Figure 5 An exploded view of the portable energy storage power supply provided in the embodiments of this application.
[0048] like Figure 1 and Figure 2 As shown, the portable energy storage power supply provided in this application embodiment includes: a power supply casing 1, a semi-solid battery module 2, a heat dissipation component 3, a display module 4, and a control module 5.
[0049] In this embodiment, the power supply housing 1 can be a square housing made of aluminum alloy. The power supply housing 1 has multiple threaded holes for fixing and mounting the semi-solid-state battery module 2, the heat dissipation assembly 3, the display module 4, and the control module 5. For example... Figure 1 As shown, with the installation direction of display module 4 as the front view, display module 4 is installed on the front of power supply housing 1, and control module 5 is installed inside power supply housing 1 and can be connected to the top surface of power supply housing 1 by bolts. Heat dissipation assembly 3 is fixedly installed on the left and right sides of power supply housing 1 by bolt connection.
[0050] Based on the above embodiments, in an optional embodiment of this application, the power supply housing 1 includes a main frame 11, a top plate 12, and a back plate 13;
[0051] The main frame 11 has a first notch on its first side for mounting the display module 4, and the second and third sides of the main frame 11 have through holes for mounting the heat dissipation component 3. The main frame 11 has a second notch on its fourth side for mounting the back plate. The first and second sides are arranged opposite to each other. The top plate 12 and the back plate 13 are detachably connected to the main frame 11.
[0052] In this embodiment, both the first and second notches can be U-shaped, rectangular, or concave. The display module 4 can be bolted to the main frame 11 at the position of the first notch. The through hole for mounting the heat dissipation component 3 can be rectangular. The top plate 12 and the back plate 13 can be detachably connected to the main frame 11 by bolting or snap-fitting.
[0053] In this embodiment, the control module 5 can be fixedly installed on the lower surface of the top plate using bolts. When the top plate 12 is fixedly installed on the main frame 11, the lower surface of the control module 5 is spaced apart from the upper surface of the semi-solid battery module 2. This prevents the heat generated by the electronic components in the control module 5 from being conducted to the heat generated by the semi-solid battery module 2, thus avoiding potential safety hazards.
[0054] Based on the above embodiments, in an optional embodiment of this application, the bottom surface of the main frame 11 is provided with a plurality of adjustable height support feet 14, and the adjustable height support feet 14 are threadedly connected to the main frame 11.
[0055] In this embodiment, the adjustable height support foot 14 may include a bolt and a base plate fixedly connected to one end of the bolt. When the user tightens the bolt, the base plate can be moved away from or closer to the bottom surface of the main frame 11, thereby adjusting the distance between the bottom surface of the main frame 11 and the ground.
[0056] When improved heat dissipation is needed or in use scenarios where there is standing water on the ground, the adjustable height support foot 14 can be raised to keep the entire portable energy storage power supply away from the ground, increase air circulation at the bottom and keep it away from the water surface, thereby improving heat dissipation and reducing the risk of water immersion, further enhancing safety.
[0057] The semi-solid battery module 2 is installed inside the power supply housing 1. The semi-solid battery module 2 includes a single cell 21 and a cell support 22. The single cell 21 is a semi-solid cell that is a mixture of solid electrolyte and liquid electrolyte.
[0058] In this embodiment, the single cell 21 is a semi-solid cell. The working principle of a semi-solid cell differs from that of a traditional liquid battery in that the electrolyte in a semi-solid cell is semi-solid, meaning the electrolyte includes both solid and liquid electrolytes. The cell support 22 is a component used to fix the single cell 21. The cell support 22 can be made of steel, metal, or alloy. The cell support 22 can support and fix the single cell 21, ensuring the stability of the single cell 21 within the semi-solid battery module 2 and preventing the single cell 21 from shifting or tipping over under vibration or impact conditions.
[0059] In an optional embodiment of this application, a single cell 21 includes a positive electrode material, a negative electrode material, a separator material, a semi-solid electrolyte, and a cell soft casing.
[0060] Figure 6 This is a schematic diagram of the external structure of a single battery cell provided in an embodiment of this application.
[0061] like Figure 6 As shown, a single cell 21 is wrapped with a cell soft outer casing to encapsulate the semi-solid electrolyte, positive electrode material, negative electrode material and separator material, with a portion of the positive electrode material and a portion of the negative electrode material exposed for series or parallel connection with other single cells.
[0062] In an optional embodiment of this application, the solid electrolyte content in the semi-solid cell is greater than 50% and less than 100%.
[0063] In this embodiment, the solid electrolyte content in the semi-solid cell can be 55%, 60%, 80%, 80%, or 90%. For improved safety, a higher solid electrolyte content is better. However, it should not be too high, as this would increase the production cost of the semi-solid cell.
[0064] Figure 7 This is a schematic diagram of the structure of the semi-solid battery module 2 provided in the embodiments of this application.
[0065] like Figure 7 As shown, based on the above embodiments, in an optional embodiment of this application, the number of single cells 21 is multiple, and the multiple single cells 21 are electrically connected in series and parallel within the cell support 22.
[0066] In this embodiment, there are multiple single cells 21, and the specific number can be set according to the design requirements and product model of the portable energy storage power supply.
[0067] Based on the above embodiments, in an optional embodiment of this application, the size of a single cell 21 is 170×135×12 mm.
[0068] In this embodiment, the single cell 21 is made into a thin sheet of 170×135×12 mm, which facilitates the stacking of multiple single cells 21 in series, which helps to reduce the volume of the entire semi-solid battery module, thereby reducing the weight and volume of the entire portable energy storage power supply.
[0069] Based on the above embodiments, as an optional embodiment of this application, the battery cell support 22 is provided with a plurality of heat dissipation fins 221.
[0070] In this embodiment, the heat dissipation fins 221 and the cell support 22 can be made of the same or different materials. For example, both can be made of iron, or the heat dissipation fins 221 can be made of copper, which has better heat dissipation performance than the cell support 22. Figure 7 As shown, heat dissipation fins 221 are evenly distributed on both sides of the cell support 22.
[0071] In an optional embodiment of this application, a heat sink 222 is provided on the cell support 22. The heat sink 222 can be fixedly connected to both sides of the cell support 22 by adhesive bonding or welding, for example: Figure 7 As shown, there are 8 heat sinks 222, which are arranged vertically and spaced apart on the left and right sides of the cell support 22.
[0072] Based on the above embodiments, in an optional embodiment of this application, the size of the semi-solid battery module 2 is 175×140×88 mm.
[0073] In this embodiment, as Figure 7 As shown, the individual cells 21 are stacked and fixedly installed in the cell bracket 22 to form a semi-solid battery module 2 with dimensions of 175×140×88 mm.
[0074] For example, a single cell 21 has a capacity of 38 Ah, a rated voltage of 3.2V, and a rated capacity of 121.6Wh. Then, the semi-solid-state battery module 2 obtained by connecting 7 cells in series has a capacity of 38 Ah, a rated voltage of 22.4V, and a rated capacity of 121.6V.
[0075] The heat dissipation component 3 is installed inside the power supply housing 1 on both sides of the semi-solid battery module 2.
[0076] In this embodiment, the heat dissipation component 3 can be an air-cooled radiator or a water-cooled radiator. For example... Figure 2 As shown, in this embodiment, the heat dissipation component 3 is an air-cooled heat sink. The heat dissipation component 3 can be fixedly installed inside the power supply housing 1 on both sides of the semi-solid battery module by means of bolt connection.
[0077] In this embodiment, the heat dissipation component 3 is electrically connected to the control module 5. When the entire portable energy storage power supply is started, the control module 5 sends a control command to the heat dissipation component 3 to make the heat dissipation component 3 operate, so as to draw the hot air inside the power supply casing 1 outward and allow the outside air to enter the power supply casing 1 for heat dissipation circulation, thereby achieving the purpose of reducing the temperature inside the power supply casing 1.
[0078] Based on the above embodiments, in an optional embodiment of this application, the heat dissipation component 3 includes an active heat dissipation component 31 and a heat dissipation plate 32.
[0079] The active heat sink 31 is installed on one side of the power supply housing 1 and is used to exhaust hot air inside the power supply housing 1 to the outside environment.
[0080] In this embodiment, the active heat dissipation component 31 can be a cooling fan or a liquid cooling heat pipe. There can be multiple cooling fans in the active heat dissipation component 31, which may include at least two cooling fans and a heat dissipation mounting plate for mounting the cooling fans. The cooling fans and the heat dissipation mounting plate can be connected by bolts. The heat dissipation mounting plate can be fixedly mounted on the side of the power supply housing 1 using bolts.
[0081] The heat sink 32 is installed on the other side of the power supply housing 1. The heat sink 32 is positioned opposite to the active heat sink 31. The heat sink 32 has heat dissipation holes 321.
[0082] In this embodiment, the heat sink 32 can be made of metal, alloy or plastic with good heat dissipation performance. The heat sink 32 can be fixedly installed on the other side of the power supply housing 1 by bolt connection. The side where the heat sink 32 is located is opposite to the side where the active heat sink 31 is located.
[0083] In this embodiment, the heat sink 32 is provided with heat dissipation holes 321 by stamping and punching. Multiple heat dissipation holes 321 are evenly distributed on the heat sink 32, serving to connect the interior of the power supply housing 1 with the external environment. When the active heat dissipation component 31 is working, hot air is discharged from the power supply housing 1. Under pressure, air from the external environment enters the interior of the power supply housing 1 through the heat dissipation holes 321, achieving air circulation heat dissipation.
[0084] In an optional embodiment of this application, the heat dissipation hole 321 is an elongated hole, and the area of the heat dissipation hole 321 is greater than half the surface area of the heat dissipation plate 32, thereby increasing the heat dissipation area. This allows the heat generated by the semi-solid-state battery module 2 to be transferred to the external environment more quickly through the heat dissipation hole 321 when the active heat dissipation component 31 is not in operation, improving the heat dissipation effect and thus enhancing the safety of the entire portable energy storage power supply.
[0085] Based on the above embodiments, in an optional embodiment of this application, a heat dissipation plate 32 is provided with a heat conduction element 322, which is located below the heat dissipation hole 321 and close to the semi-solid battery module 2.
[0086] In this embodiment, the heat-conducting component 322 can be a plate made of a material with better thermal conductivity than the heat sink 32, and the heat-conducting component 322 can be fixedly installed on the outer surface of the heat sink 32 by welding or bonding.
[0087] In an optional embodiment of this application, the heat sink 32 is further provided with a rectangular hole for mounting the heat-conducting component 322. After the heat-conducting component 322 is mounted in the rectangular hole, one surface of the heat-conducting component 322 is in contact with the air inside the power supply housing 1, and the other surface of the heat-conducting component 322 is in contact with the air outside the power supply housing 1, thereby quickly conducting the heat in the power supply housing 1 to the external environment.
[0088] Based on the above embodiments, in an optional embodiment of this application, the active heat sink 31 further includes a temperature sensor electrically connected to the control module 5. The temperature sensor monitors the temperature inside the power supply casing 1. When the control module 5 detects that the temperature reflected by the temperature signal monitored and sent by the temperature sensor is greater than a preset upper limit temperature, such as 45°C, the control module 5 can send a control signal to control the active heat sink 31 to operate and perform heat dissipation. When the control module detects that the temperature reflected by the temperature signal monitored and sent by the temperature sensor is less than the preset upper limit temperature, such as 45°C, it indicates that the semi-solid battery module 2 is in a safe operating state and does not require heat dissipation. At this time, the active heat sink 31 can be controlled to stop operating to save energy.
[0089] Display module 4 is mounted on the outer surface of power supply housing 1.
[0090] In this embodiment, the display module 4 includes a charging socket, a display screen, and a power-on button. The charging socket can be fixedly installed on the side of the battery casing 1 using bolts, and is used to connect the user's electrical equipment. The display screen can be used to display information such as the remaining capacity, power supply, and real-time temperature of the entire portable energy storage power supply. The power-on button allows the user to manually start the entire portable energy storage power supply, thereby enabling the semi-solid-state battery module 2 to supply power to the electrically connected user equipment. The display module 4 can be equipped with multiple interfaces such as AC, DC, Type-C, USB, and PD to match mainstream electronic devices on the market, and is suitable for various scenarios such as outdoor travel, emergency rescue, medical relief, and outdoor operations.
[0091] The control module 5 is electrically connected to the semi-solid battery module 2, the heat dissipation component 3, and the display module 4. The control module 5 is installed inside the power supply housing 1.
[0092] In this embodiment, the control module 5 can be a control board that integrates control components, such as a PCB board. The control module 5 may include power conversion components, power control components, power protection components, and intelligent management components.
[0093] Among these, the power conversion components can be current / voltage converters. These components are used to control the conversion of input power (such as AC or DC) into a stable and reliable DC power supply suitable for outdoor electronic equipment. This is achieved through internal power conversion circuitry, which can adjust the voltage and current as needed.
[0094] Power control components can be power converters, used for precise control of power supply output. They can automatically adjust the output power according to the needs of connected electronic devices to avoid overload or wasted energy, adapting to devices with different charging capacities.
[0095] Power protection components can be emergency power-off switches. Power protection components are used to quickly cut off the output or reduce the power when the power system malfunctions, so as to protect the safety of electronic equipment and users.
[0096] Intelligent management components can be chips or microcontrollers. They are used to monitor the battery status in real time, optimize the charging and discharging process, and extend the battery's lifespan.
[0097] In an optional embodiment of this application, data obtained from the inventor's experiments show that the portable energy storage power supply with two kilowatt-hours provided in this application embodiment can control the weight to within 20 kilograms, which is lower than the approximately 30 kilograms of outdoor power supplies in the prior art. Furthermore, the portable energy storage power supply with two kilowatt-hours provided in this application embodiment is also one-third smaller in volume than existing outdoor power supplies, making it more convenient to handle, transport, store, and use, thereby improving user convenience.
[0098] The portable energy storage power supply provided in this application embodiment can be used in solar energy storage. The semi-solid-state battery module 2, due to its high energy density and long cycle life, can effectively store solar energy and release it when needed, improving the efficiency of solar energy utilization. In terms of smart grids, the high security and power / capacity decoupling characteristics of the semi-solid-state battery module 2 make it a more ideal energy storage medium, helping to stabilize grid operation and improve energy utilization efficiency.
[0099] Meanwhile, due to its relatively low cost, the semi-solid-state battery module 2 also has advantages in the commercial application of smart energy storage power supplies. Through large-scale production and application, the production cost of the semi-solid-state battery module 2 will be further reduced, thereby further promoting its application in the field of smart energy storage power supplies and ultimately reducing the overall price of portable energy storage power supplies.
[0100] In summary, the portable energy storage power supply provided in this application embodiment, by using a semi-solid battery module 2, has a lower content of liquid electrolyte in the semi-solid battery, making it less prone to leakage and combustion problems. Furthermore, the semi-solid battery module 2 uses a semi-solid cell with a mixture of solid and liquid electrolytes, which reduces the weight and volume of the entire portable energy storage power supply for the same capacity, thus improving the safety and convenience of the entire portable energy storage power supply.
[0101] Meanwhile, the single cell is designed as a thin plate of 170×135×12 mm, which shortens the distance between the positive and negative electrodes, for example, to no more than 20 micrometers. This makes the entire semi-solid battery module 2 smaller and lighter, improving the convenience of the entire portable energy storage power supply.
[0102] This description is intended to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
