The battery of one embodiment of the present invention includes a battery case 10, a battery cell 20, and a conductive member 30, and the conductive member 30 electrically connected to the battery cell 20 extends to a position right below the electrolyte injection hole 11, so as to shield the electrolyte injected from the electrolyte injection hole 11, thereby reducing the flow rate of the electrolyte, and also changing the flow direction of the electrolyte, thereby preventing an active material coated on the battery cell 20 from being washed away, or causing damage to the battery cell 20, and thus improving the performance of the battery.
It should be noted that the conductive member 30 extends to just below the pour hole 11, that is, the conductive member 30 is directly opposed to at least a part of the pour hole 11, so that the electrolyte injected from the pour hole 11 can be made to directly impact the conductive member 30, thereby reducing the flow rate of the electrolyte and changing the flow direction of the electrolyte. The conductive member 30 is used to charge and discharge the battery. The conductive member 30 may include a tab portion 31, an adapter sheet 32 or a pole terminal 33, and at least one of the tab portion 31, the adapter sheet 32 and the pole terminal 33 may extend to a position right below the injection hole 11, but it is necessary to ensure that the injection hole 11 is not blocked.
The battery includes a cell 20 and an electrolyte, and is a minimum unit capable of performing electrochemical reactions such as charge/discharge. The battery cell refers to a unit formed by winding or laminating a stack including a first electrode, a separator, and a second electrode. When the first electrode is a positive electrode, the second electrode is a negative electrode. Wherein the polarities of the first electrode and the second electrode can be interchanged. The first electrode and the second electrode are coated with an active material.
In one embodiment, as shown in fig. 2 and 3, the conductive member 30 includes a tab portion 31, and the tab portion 31 is connected to the battery cell 20. The tab portions 31 extend from one side of the battery cell 20, the tab portions 31 may be two, and the two tab portions 31 may extend from two opposite sides of the battery cell 20.
In one embodiment, the tab portion 31 extends to just below the liquid injection hole 11, so that the tab portion 31 is directly opposed to at least part of the liquid injection hole 11, so that the electrolyte injected from the liquid injection hole 11 can be made to directly impact the tab portion 31, thereby reducing the flow rate of the electrolyte and changing the flow direction of the electrolyte.
In one embodiment, as shown in fig. 2 and 3, the conductive member 30 further includes an adaptor sheet 32, the adaptor sheet 32 is connected to the tab portion 31, and the adaptor sheet 32 is disposed to facilitate the connection of the tab portion 31.

Alternatively, the interposer 32 may be connected to a bus bar to achieve series and parallel connection between the batteries.
In one embodiment, the adapter sheet 32 extends to the position right below the liquid injection hole 11, so that the adapter sheet 32 is directly opposite to at least part of the liquid injection hole 11, and therefore, the electrolyte injected from the liquid injection hole 11 can directly impact the adapter sheet 32, so that the flow rate of the electrolyte is reduced, and the flow direction of the electrolyte is changed.
In some embodiments, tab 31 may extend directly below pour hole 11, and at the same time, adaptor piece 32 may extend directly below pour hole 11, where tab 31 and adaptor piece 32 may respectively block a portion of pour hole 11.

In one embodiment, at least one of the fusing part 322 and the second connecting part 323 is provided with an insulating part to prevent at least one of the fusing part 322 and the second connecting part 323 from directly contacting the tab part 31, so as to prevent the tab part 31 from being electrically disconnected from the second connecting part 323 after the fusing part 322 electrically disconnects the first connecting part 321 from the second connecting part 323, because the tab part 31 directly contacts the fusing part 322 and the second connecting part 323.
When the tab 31 is long, for example, if the tab 31 extends to just below the injection hole 11, and at this time, if an insulating portion is not provided on at least one of the fusion portion 322 and the second connection portion 323, the free end of the tab 31 may come into contact with the fusion portion 322 and the second connection portion 323, and therefore, after the fusion portion 322 electrically disconnects the first connection portion 321 and the second connection portion 323, the second connection portion 323 and the tab 31 cannot be electrically disconnected, which causes a safety problem.
The insulating part may be a coating, such as alumina (Al)2O3) Zirconium oxide (ZrO)2) And a coating layer is coated on at least one of the fusing part 322 and the second connecting part 323. The insulating part may also have other structures, such as a rubber structure, and the rubber structure may be bonded to at least one of the fusing part 322 and the second connecting part 323.
