[0038] Recently, the application of lithium-ion batteries has become increasingly popular and is increasingly closely connected with people's daily lives. From wearable watches, headphones, glasses, daily necessary communication tools (such as mobile phones), and power tools for improving efficiency and convenience, to electric bicycles and electric cars for transportation, lithium-ion batteries are widely used. Their long life, high energy density, and high safety performance have greatly facilitated people's lives.

[0039] The safety and performance of lithium-ion batteries are receiving more and more attention. The electrolyte is the core raw material of lithium-ion batteries, and its quality directly affects the performance of lithium-ion batteries, which in turn affects the user experience. The electrolyte is a mixture, generally composed of a certain concentration of LiPF6 (lithium hexafluorophosphate) electrolyte salt and solvents such as EC (ethylene carbonate), DMC (dimethyl carbonate), DEC (diethyl carbonate), PC (polycarbonate), and some additives with different functions such as improving circulation, high and low temperature, etc.

[0040] In the industrial production process, lithium-ion batteries are generally transported from large liquid reservoirs placed in designated rooms through dedicated pipelines to the electrolyte storage reservoir body of the filling machine. When in use, a pump draws the electrolyte buffered in the reservoir body into the filling cup at the filling port, and injects it into the lithium-ion battery through circulating pressure to complete the filling action.

[0041] The electrolyte in the storage tank (whether it is a machine or a warehouse) will be deposited and crystallized due to long-term storage, resulting in the inhomogeneity of the electrolyte mixed solution, which in turn causes the performance of lithium-ion batteries to decline, and even abnormalities, such as: large differences in the first effect of the same batch, unstable interface, partial scars, large internal resistance, reduced rate performance, reduced life, swelling, etc., which affect the user experience. To a certain extent, it also causes waste of resources and environmental pollution, which is not conducive to the construction of an economical society and the requirements of sustainable development.

[0042] Figure 1 The schematic diagram of the structure of the electrolyte storage device according to the embodiment of the present invention is shown schematically. Figure 1 As shown, the present invention proposes an electrolyte storage device.

The inlet end of the liquid outlet component passes through the liquid storage container 10 and is located in the accommodating chamber 111. The outlet end of the liquid outlet component is located outside the liquid storage container 10. The deposition component includes a driving member 41 and a stirring member. The stirring member is arranged in the accommodating chamber 111. The driving end of the driving member 41 passes through the liquid storage container 10 and is connected to the stirring member so that the stirring member rotates along its own axis.

[0043] According to the technical solution of the present invention, the accommodating chamber 111 of the liquid storage container 10 is used to accommodate the electrolyte of the battery, the liquid inlet component can transport the electrolyte from the outside to the accommodating chamber 111, and the liquid outlet component can transport the electrolyte in the accommodating chamber 111 to the outside. After the electrolyte is in the accommodating chamber 111, the driving member 41 of the anti-deposition component can drive the stirring member to rotate in the accommodating chamber 111 and drive the electrolyte to rotate, so that the electrolyte in the accommodating chamber 111 flows, thereby preventing the electrolyte from being deposited and crystallized, and improving reliability.

Part of the liquid inlet pipe 20 passes through the liquid inlet hole and extends into the accommodating chamber 111 to transport the electrolyte of the battery to the accommodating chamber 111. In addition, the liquid inlet assembly also includes a first sealing ring 22, which is sleeved outside the liquid inlet pipe 20 and abuts against a side of the cover body 12 away from the liquid storage container 10, and is used to seal the position of the connection between the liquid inlet pipe 20 and the cover body 12, thereby improving the sealing performance of the liquid inlet assembly.

The inlet end of the liquid outlet pipe 30 directly reaches the bottom of the container body 11, and the inlet end of the liquid outlet pipe 30 is set at 45° to the vertical direction, and directly reaches the bottom side wall of the accommodating chamber 111 to prevent interference with the stirring blades 42, and at the same time prevent air from entering when there is no liquid at the inlet end of the liquid inlet pipe 20, thereby playing a sealing role.

[0048] Specifically, in this embodiment, if Figure 1 As shown, a second on-off valve 31 is provided on the liquid outlet pipe 30 , which can perform on-off operations on the pipeline in the liquid outlet pipe 30 .

In this embodiment, the stirring member is disposed at the bottom of the accommodating chamber 111, and can rotate from the bottom of the accommodating chamber 111 after the electrolyte is filled into the accommodating chamber 111, thereby stirring the electrolyte in the accommodating chamber 111, so that the stirring member rotates in the accommodating chamber 111, and drives the electrolyte to rotate, so that the electrolyte in the accommodating chamber 111 flows, preventing the electrolyte from being deposited and crystallized, and improving reliability. If the stirring member is disposed at the top of the accommodating chamber 111, when the electrolyte capacity is small, the electrolyte will not be in contact with the stirring member, and the purpose of stirring the electrolyte by the stirring member cannot be achieved.

[0056] Specifically, in this embodiment, if Figure 1 As shown, the stirring member includes a plurality of stirring blades, and the plurality of stirring blades are arranged at intervals along the rotation direction of the stirring blades, and can rotate with the driving end of the driving member 41, thereby driving the electrolyte in the accommodating chamber 111 to rotate.

In this embodiment, a first opening is arranged at the bottom end of the container body 11. The first end of the liquid level gauge passes through the first opening and reaches the bottom end of the accommodating cavity 111, and is used to communicate with the electrolyte in the accommodating cavity 111. The second end of the liquid level gauge is arranged outside the container body 11, and is used to display the depth information of the electrolyte in the accommodating cavity 111.

[0058] In some embodiments of the present invention, Figure 1As shown, the liquid level gauge includes a first connecting tube 513, a second connecting tube 512 and a liquid level tube 511.
