[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0020] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0021] The utility model provides a battery, such as Figure 1 and Figure 2As shown, the battery comprises a housing 10, a battery cell 20 disposed within the housing 10, and at least one liquid storage member 30. The housing 10 is filled with electrolyte, and the liquid storage member 30 has a sealed liquid storage chamber 31 filled with electrolyte. The liquid storage chamber 31 is capable of rupturing to release the electrolyte under predetermined conditions. The shape of the housing 10 can be customized, such as rectangular or circular, and can be made of either hard or soft materials. The battery cell 20 can be configured in a conventional manner, such as by rolling the anode and cathode into a cylindrical shape with insulating material interposed between them. After the battery cell 20 is placed within the housing 10, a space for filling the electrolyte is provided within the housing 10. The liquid storage member 30 can then be installed within this space. The shape of the liquid storage member 30 and the electrolyte storage capacity of the liquid storage chamber 31 can be customized, such as the electrolyte capacity of the liquid storage chamber 31 being 0.2 to 1 g. The liquid storage member 30 can be secured to the inner wall of the housing 10 by bonding, snapping, or other methods. Furthermore, the liquid storage member 30 is made of a material that can rupture under specific conditions (this material, upon rupture, does not damage other battery components and does not chemically react with the electrolyte). This allows the liquid storage member 30 to rupture to release electrolyte when the electrolyte capacity decreases, thereby increasing the electrolyte capacity within the outer shell 10. The rupture location can be at the end, the middle, or the entirety of the liquid storage member 30. In this embodiment, by providing the liquid storage member 30 within the outer shell 10 to store electrolyte, the electrolyte can be replenished if the electrolyte within the outer shell 10 decreases, thereby extending the battery's service life.

[0022] In a preferred embodiment, multiple liquid storage members 30 are preferably provided, and the multiple liquid storage members 30 are arranged around the battery cell 20. The liquid storage cavities 31 within the multiple liquid storage members 30 can have the same or different capacities, allowing the user to release an appropriate amount of electrolyte according to usage. The liquid storage member 30 can be positioned within the housing 10 based on design requirements or user experience, placing it in an area with a more severe electrolyte shortage, thereby achieving rapid electrolyte replenishment.

[0023] In a preferred embodiment, if Figure 1 As shown, the liquid storage member 30 is preferably tubular, with a length of 5-10 mm and a diameter of 0.2-1 mm. In this case, the housing 10 is preferably rectangular, with the battery cell 20 located in the center of the housing 10. A liquid storage member 30 is provided at each of the four corners of the housing. This increases the distance between the liquid storage member 30 and the battery cell 20, thereby preventing damage to the battery cell 20 when the liquid storage member 30 is ruptured by external force.

[0024] In a preferred embodiment, the liquid storage element 30 is preferably ruptured under ultrasonic conditions. The preferred material is polypropylene with 20%-30% glass fiber added. The ultrasonic frequency is 50-100W and the power is 20-80kHz. Under these conditions, the ultrasonic head can be aligned with the position of the liquid storage element 30 on the housing 10 to rupture the liquid storage element 30 and release the electrolyte.

[0025] In a preferred embodiment, the rupture pressure of the liquid storage element 30 is preferably 100-200 kgf, and the preferred material is silicone. After prolonged battery use, the pressure inside the outer shell 10 increases. This increased pressure can be used to rupture the liquid storage element 30 and release the electrolyte without damaging the outer shell 10. Of course, if the outer shell 10 is made of a flexible material, such as a battery pack, the liquid storage element 30 can also be ruptured by external pressure to release the electrolyte.

[0026] In a preferred embodiment, the rupture temperature of the liquid storage element 30 is preferably between 90°C and 130°C, and the preferred material is a thermoplastic elastomer. The normal operating temperature of the battery generally does not exceed 75°C, so under normal circumstances, the liquid storage element 30 will not rupture. However, when electrolyte replenishment is required, external heating can rupture the liquid storage element 30, thereby releasing the electrolyte. In this case, the housing 10 and battery cell 20 preferably have much greater high-temperature resistance than the liquid storage element 30 to avoid damage to the housing 10 and battery cell 20 when heating the liquid storage element 30.

[0027] In a preferred embodiment, the outer surface of the housing 10 preferably has a marking pattern corresponding to the position of the liquid storage member 30. The marking can be formed on the surface of the housing 10 by coating, attaching, engraving, etching, etc., so as to accurately identify the position of the liquid storage member 30 within the housing 10 when the liquid storage member 30 is ruptured. The marking can be a conventional symbol corresponding to the conditions for rupturing the liquid storage member 30. For example, when rupturing the liquid storage member 30 by temperature, the marking pattern can be a flame pattern. When rupturing the liquid storage member 30 by ultrasound or external heating, the ultrasonic head or heating element only needs to be brought close to the marking pattern.

[0028] The above are only some or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
