Description

Technical Field

[0001] The present invention relates to the technical field of sodium-ion batteries, and particularly relates to a high-power sodium-ion battery. Background Art

[0002] A high-power sodium-ion battery is a secondary battery that relies on the movement of sodium ions between the positive and negative electrodes to complete charge and discharge. The positive electrode of a sodium-ion battery usually uses vanadate materials, while the negative electrode uses carbon materials or titanium oxides. When charging, sodium ions migrate from the positive electrode to the negative electrode and are embedded in carbon or titanium oxides at the negative electrode. When discharging, sodium ions are released from the negative electrode and return to the positive electrode, while releasing the stored energy.

[0003] For example, a sodium-ion battery with an application number of CN217463040U and a publication date of September 20, 2022, includes a sodium-ion battery housing and a sodium-ion battery base.

[0036] Working principle: When the high-power single battery 14 bulges, it will push the contact network 18 to move. The contact network 18 will push the fixed block 23 to move. The fixed block 23 will drive the connecting rod 24 to move. Since the connecting rod 24 is rotatably connected to the fixed block 23 and the slider 20 respectively, when the connecting rod 24 moves, it will tilt and also push the slider 20 to move. The movement of the slider 20 will squeeze the contact switch 22.

When the high-power sodium-ion battery operates, it will generate heat. The cooling fan 28 blows air on the high-power single battery 14 for heat dissipation, and the heat is dissipated to the outside of the side case 2 through the heat dissipation net 35. After a period of time, during the period when the cooling fan 28 is turned off, the motor 32 is activated to drive the lead screw 33 to rotate and the guide block 31 to move. The guide block 31 will drive the cleaning brush 29 to move to clean the dust on the dust-proof net 37, avoiding the dust blocking the dust-proof net 37 and realizing the self-cleaning function. When it is necessary to repair the high-power single battery 14, pull the pull rod 11 to drive the extrusion block 10 to move. At this time, the clamping block 8 is not squeezed by the extrusion block 10, and the elastic force of the first spring 9 will push the clamping block 8 to move, enabling the clamping block 8 to move out of the inside of the connecting block 7. Pull the two side cases 2 to both sides of the bottom plate 1, and the anti-disengagement block 3 slides inside the bottom plate 1, then the side case 2 and the bottom plate 1 can be disassembled, which is convenient for repairing the high-power single battery 14.
