The present invention is described in further detail below with reference to the drawings to enable those skilled in the art to practice the invention by referring to the description.
The open portion of the pouch cell described herein is a tab on the pouch cell housing that has an opening through which liquid outside the pouch cell can enter the pouch cell when the opening is open.
Example 1
As shown in fig. 1-3, a sealing mechanism for a pouch cell and a schematic view for sealing a pouch cell are provided, the sealing mechanism is a hollow and open-ended clamp 1, the clamp 1 has a slot 2, and the clamp has a certain elasticity, and can apply a clamping force to the open portion of the pouch cell by its own elasticity, as shown in fig. 3, when in use, the open portion 10 is extended into the hollow interior of the clamp 1 through the slot 2, and the open portion 10 is sealed by the resilience of the clamp due to the certain resilience of the clamp. At least a part of the clamping member is made of a material soluble in an electrolyte, for example, the upper half part or the lower half part of the slot, so long as the opening part 10 is fully or partially opened after dissolution, the clamping member is preferably fully soluble in the electrolyte, and the clamping member is made of one of polymethyl methacrylate, silicone rubber polyvinyl chloride, polycarbonate or ABS plastic, and the material is soaked in the electrolyte and can be dissolved by the electrolyte. Therefore, when the pouch battery having the clamping member 1 is placed in an electrolyte, the clamping member is immersed in the electrolyte, and the clamping member is dissolved by the electrolyte, so that the clamping force to the opening portion 10 is lost, the opening portion 10 is opened, and the external electrolyte can enter the inside of the battery through the opening portion 10.
The sealing mechanism is used for sealing the opening part, the structure is simple, the sealing mechanism is automatically dissolved by electrolyte when immersed in the electrolyte, so that the opening part is opened, the opening is opened without external mechanical operation, and the use is convenient.
Example 2
As shown in fig. 4, another sealing mechanism of the present invention includes a first clamping plate 3, a second clamping plate 4, and a plurality of bolts 5, wherein a plurality of through holes are formed on the first clamping plate 3 and the second clamping plate 4, when in use, an opening portion 10 is placed between the first clamping plate 3 and the second clamping plate 4, the bolts 5 penetrate through the through holes to connect the first clamping plate 3 and the second clamping plate 4, the opening portion 10 is sealed and clamped, and sealing gaskets 6 can be arranged between the first clamping plate 3 and the opening portion 10 and/or between the second clamping plate 4 and the opening portion 10, preferably only one sealing gasket is arranged, so that cost is saved and sealing effect can be achieved. The rivet is made of electrolyte-soluble materials, such as polymethyl methacrylate, silicone rubber polyvinyl chloride, polycarbonate or ABS plastic, which are dissolved by the electrolyte after being soaked in the electrolyte. Therefore, when the pouch battery having the sealing mechanism is placed in an electrolyte, the sealing mechanism is soaked in the electrolyte, the rivet 5 is dissolved by the electrolyte to disappear, and thus the clamping force to the opening portion 10 is lost, the opening portion 10 is opened, and the electrolyte outside the battery can enter the interior of the pouch battery through the opening portion 10.
In some embodiments, the materials of the first clamping plate 3 and the second clamping plate 4 may also be made of materials soluble in electrolyte, when the soft-packed battery with the sealing mechanism is placed in the electrolyte, the opening part is soaked in the electrolyte, and the first clamping plate 3, the second clamping plate 4 and the rivet 5 are dissolved by the battery, so that the sealing effect on the opening part is lost, the opening part is opened, and the external electrolyte can enter the interior of the soft-packed battery through the opening part.
When the first clamping plate 3, the second clamping plate 4 and the rivet 5 are made of materials which are soluble in electrolyte, the soft package battery can be opened more quickly. It will be readily apparent to those skilled in the art that one, or two or three of the first clamping plate, the second clamping plate and the rivet may be selected to be made of electrolyte-soluble materials, depending on the speed at which the pouch cell needs to be opened to open the opening.
The sealing mechanism is used for sealing the opening part, the structure is simple, the sealing mechanism is automatically dissolved by electrolyte when immersed in the electrolyte, so that the opening part is opened, the opening is opened without external mechanical operation, and the use is convenient.
Of course, the first clamping plate 3 and the second clamping plate 4 may be clamped by providing concave-convex matching parts or other matching parts on the first clamping plate 3 and the second clamping plate 4 without using the bolts 5, so that one or both of the first clamping plate 3 and the second clamping plate 4 may be made of a material soluble in the electrolyte.
The bolts 5 in the figure can be more conveniently connected and fixed by rivets (the rivets in the figure 5 are nuts).
Example 3

In order to further improve the sealability, a sealing gasket 6 may be provided between the outer clip 7 and the opening portion 10, or between the inner support and the opening 10 of the pouch cell case, or a sealing gasket 6 may be provided between the outer clip 7 and the opening portion 10, or between the inner support and the opening 10 of the pouch cell case. Under the action of the sealing mechanism, the opening 10 of the soft package battery case is sealed, and external air and liquid cannot enter the soft package battery.

Therefore, when the pouch battery having the sealing mechanism is placed in an electrolyte, the sealing mechanism is immersed in the electrolyte, the outer clip 7 is dissolved by the electrolyte, so that the sealing effect on the opening portion is lost, the opening portion is opened, and the external electrolyte enters the interior of the pouch battery.
In other embodiments, the outer collar 7 and the inner support 8 are made of materials that are soluble in the electrolyte, so that the opening portion is opened more quickly and easily, and thus when the pouch cell having the sealing mechanism is placed in the electrolyte, the sealing mechanism is immersed in the electrolyte, the outer collar 7 and the inner support 8 are dissolved by the electrolyte, the sealing mechanism loses the sealing effect on the pouch cell, the opening portion 10 is opened, and the external electrolyte enters the interior of the pouch cell.
In some embodiments, the outer band 7, the inner support 8 and the sealing gasket 6 are all made of a material that is soluble in the electrolyte, such that when the sealing mechanism is immersed in the electrolyte, the entire sealing mechanism is dissolved.
In some embodiments, the inner support may be a C-shaped hollow tube conforming to the shape of the outer collar, or may be a solid round tube as shown in fig. 6.
As will be readily appreciated by those skilled in the art, the cross-sectional shape of the outer clip may be not only a C-shaped hollow tube, but also a hollow tubular structure having a square or trapezoidal cross-section, and the inner support may be matched with the hollow shape of the outer clip to provide a supporting force against the opening portion, thereby sealing the opening portion.
The sealing mechanism is used for sealing the opening part, the structure is simple, the sealing mechanism is dissolved by electrolyte when immersed in the electrolyte, so that the opening part is opened, the opening is opened without external mechanical operation, and the use is convenient.
