[0031] With the development of society and the economy, portable power supplies are being used more and more in daily life. Portable power supplies can provide temporary power to small household appliances such as mobile phones and computers. Due to the advantages of lithium-ion batteries, such as high energy density, fast charging speed, low self-discharge rate, and long cycle life, portable power supplies usually use lithium-ion batteries as energy storage modules.
[0032] However, lithium-ion batteries are quite sensitive to temperature. High temperatures accelerate the aging of lithium-ion batteries, significantly reducing their lifespan. Furthermore, thermal runaway in lithium-ion batteries can lead to fires or even explosions.
[0033] To ensure stable heat dissipation and reliable safety of portable power supplies, this invention introduces an immersion-type portable power supply device.
[0034] like Figure 1 As shown, the immersion portable power supply device mainly includes a housing structure 1, an energy storage module 2, an input module 8, and an output module 9.

[0036] The first chamber 6 is filled with supramolecular coolant 3. The energy storage module 2 is submerged below the surface of the supramolecular coolant 3. The supramolecular coolant 3 possesses properties such as thermal conductivity, insulation, and flame retardancy.
[0037] Preferably, the energy storage module 2 is connected to the bottom wall of the first chamber 6. The liquid level of the supramolecular coolant 3 is greater than the height of the energy storage module 2.
[0038] Furthermore, the energy storage module 2 is configured as a lithium-ion battery with high energy density. Moreover, unlike nickel-cadmium or nickel-metal hydride batteries, lithium-ion batteries do not have a significant memory effect. Users do not need to fully discharge and recharge the battery each time; they can charge it at any time, greatly improving user convenience.
[0039] In addition, the shell structure 1 is made of a material with good heat transfer properties. For example, the shell structure 1 is made of stainless steel, aluminum, or high-density PP material. In this way, the heat generated by the energy storage module 2 can be transferred to the shell structure 1 through the supramolecular coolant 3, and then the shell structure 1 releases the heat to the external environment.
[0040] In this embodiment, the energy storage module 2 is immersed in supramolecular coolant 3. The supramolecular coolant 3 is used to conduct heat and retard flame for the energy storage module 2, which not only improves the heat dissipation efficiency and enables the energy storage module 2 to dissipate heat stably, but also improves the safety of the energy storage module 2 in the event of thermal runaway, avoiding fire and explosion.

[0044] The first chamber 6 is isolated from the second chamber 7, and is used to seal the supramolecular coolant 3 inside the first chamber 6.
[0045] Based on the above embodiments, another embodiment of the present invention introduces an immersion portable power supply device.
[0046] The input module 8 is installed in the second chamber 7, and the input module 8 at least partially penetrates the side wall of the housing structure 1 for electrical connection with an external power supply for charging.
[0047] Based on the above embodiments, another embodiment of the present invention introduces an immersion portable power supply device.

An input module 8 is electrically connected to the energy storage module 2 for supplying electrical energy to the energy storage module 2. An output module 9 is electrically connected to the energy storage module 2 for outputting the electrical energy from the energy storage module 2.
[0052] The first chamber 6 is filled with supramolecular coolant 3. The energy storage module 2 is submerged below the surface of the supramolecular coolant 3.
[0053] Furthermore, the immersion portable power device also includes an energy storage management module 10. The energy storage management module 10 is installed in the second chamber 7 and is electrically connected to the energy storage module 2, the input module 8, and the output module 9.
[0054] Furthermore, the energy storage management module 10 collects the voltage and temperature of the energy storage module 2 in real time. Based on the voltage and temperature of the energy storage module 2, the workload of the input module 8 and the output module 9 is adjusted. Thus, the energy storage management module 10 provides control and protection functions for the portable power device, improving the thermal management efficiency of the portable power device.
[0055] In practical use, input module 8 is connected to a 220V power grid to charge energy storage module 2. Energy storage module 2 can discharge externally through output module 9. For example, it can be connected to household appliances such as mobile phones and computers through output module 9 to provide power.

Furthermore, the outer peripheral wall of the handle 5 is connected to the top surface of the housing structure 1. By providing the handle 5, it is convenient for users to carry and transfer the device.
