Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a formation cabinet. Background Technology

[0002] In lithium battery manufacturing, the positive electrode, negative electrode, and electrolyte of the battery must undergo a formation process to activate the electrochemical reactivity of the electrode materials in order to achieve the performance required by the design.

[0003] The formation process promotes the adjustment and activation of the internal structure of electrode materials through electrochemical charge and discharge, enabling the electrode materials to fully absorb and release lithium ions. Through the formation process, the interface between the electrolyte and the electrode can be optimized, ensuring a stable ion transport path, thereby improving the battery's conductivity and charge / discharge efficiency. Optimized electrode activation and the electrolyte interface help reduce the rate of performance degradation during cyclic charge and discharge, extending the battery's lifespan. Structural adjustment and optimization during the formation process can increase the battery's energy density, enhancing its energy storage capacity for the same volume and weight.

[0004] The formation process not only helps improve the battery's electrical performance, but also effectively reduces potential safety risks during battery use. By controlling and monitoring the charging process, the risk of short circuits inside the battery can be reduced. The formation process can ensure the tight bonding and stability of the battery's internal components, reducing the possibility of battery damage under high temperature or other extreme conditions.

[0005] The lithium-ion battery formation process plays a crucial role in ensuring battery performance, safety, and product quality. It is an indispensable key step in modern battery manufacturing. Formation is a critical process step in lithium-ion battery manufacturing, requiring advanced technology and quality control to prevent short circuits. Internal short circuits can usually be eliminated through technical monitoring. However, external short circuits are also a serious safety risk, potentially leading to battery damage, combustion, or even explosion. External short circuits cannot be eliminated through monitoring technology. Therefore, there is an urgent need for a formation cabinet that protects against external short circuits to reduce the risk of external short circuits caused by incorrect battery connections during the lithium-ion battery formation process. Utility Model Content

[0006] Therefore, this application provides a formation cabinet in an attempt to solve or at least alleviate at least one of the above-mentioned problems.

[0007] According to one aspect of this application, a formation cabinet is provided, comprising:

[0008] The cabinet body, with guide rails installed on the inner side of the cabinet body;

[0009] Several charging boards are arranged in parallel inside the cabinet and connected in series on the guide rail. A first gap is reserved between any two adjacent charging boards for placing the battery to be tested. Each charging board has at least one pair of connecting contact points on one surface facing the first gap. Each pair of connecting contact points includes two connecting contact points, which are used to connect the positive and negative terminals of the corresponding battery to be tested, respectively.

[0010] An insulating assembly includes a connecting guide rod and a plurality of insulating strips connected to the connecting guide rod. The connecting guide rod passes through the charging plate and is movable along a first predetermined direction. The first predetermined direction is parallel to a surface of the charging plate facing a first gap in the book search area. The insulating strips are disposed in the first gap corresponding to the connecting contact points and are movable along the first predetermined direction under the drive of the connecting guide rod. When the connecting guide rod moves along the first predetermined direction to a first position, the insulating strips close the connecting contact points. When the connecting guide rod moves along the first predetermined direction to a second position, the insulating strips open the connecting contact points.

[0011] According to the formation cabinet of this application embodiment, an insulating barrier is provided between two adjacent charging boards. The connecting rod controls the opening or closing of the connecting contacts on the charging board by the insulating barrier. The connecting contacts can be closed (i.e. insulated) during the battery loading and unloading process, so as to avoid the positive and negative terminals of the battery under test from contacting the same connecting contact at the same time, which would cause an external short circuit of the battery. This effectively avoids serious heat and safety problems caused by rapid battery discharge.

[0012] Optionally, in the aforementioned formation cabinet, a pair of connecting contact points are respectively provided at both ends of one surface of the charging plate facing the first gap, perpendicular to the extension direction of the guide rail.

[0013] This setup allows for simultaneous formation of two batteries under test using the same charging board, which helps improve formation efficiency.

[0014] Optionally, the cabinet has two sides parallel to the surface of the charging plate facing the first gap, and each charging plate has a first sliding hole parallel to the bottom plate surface of the cabinet. The connecting guide rod passes through the first sliding hole, and the longitudinal direction of the first sliding hole is consistent with the first predetermined direction. When the connecting guide rod slides along the longitudinal direction of the first sliding hole, the insulating strip opens or closes the connection contact point.

[0015] By setting the first sliding hole, it can be ensured that the insulating strip moves more smoothly left and right in the first predetermined direction under the drive of the connecting guide rod, thereby ensuring the efficiency and quality of the closing and opening of the contact point of the insulating strip.

[0016] Optionally, the formation cabinet also includes an insulation component control mechanism, which is connected to the connecting guide rod and controls the sliding of the connecting guide rod within the first sliding hole. Compared to manually adjusting the position of the connecting guide rod by toggling it, the insulation component control mechanism makes adjusting the position of the connecting guide rod more convenient.

[0017] Optionally, the insulation component control mechanism includes two X-shaped brackets located on both sides of the cabinet. Each X-shaped bracket includes a first crossbar and a second crossbar pivotally connected together. The first crossbar and the second crossbar are provided with second sliding holes. The longitudinal direction of the second sliding hole on the first crossbar is consistent with the length extension direction of the first crossbar, and the longitudinal direction of the second sliding hole on the second crossbar is consistent with the length extension direction of the second crossbar. Each end of the two X-shaped brackets is connected to the end of the connecting guide rod through the second sliding hole.

[0018] Optionally, the insulation component control mechanism further includes a push rod and a handle, one end of the push rod being pivotally connected to any of the connecting guide rods, and the other end being connected to the handle. By employing this insulation component control mechanism including two X-shaped brackets, the cost of this component can be reduced while ensuring high reliability of the insulation component control mechanism.

[0019] Optionally, in one example, the connecting guide rod is cylindrical, and the first sliding hole and the second sliding hole are oblong holes. By setting the connecting guide rod to a cylindrical shape and setting the first and second sliding holes to oblong holes, it is possible to ensure that the sliding of the connecting guide rod within the first and second sliding holes is smoother, facilitating the adjustment of the position of the insulating strip.

[0020] Optionally, in one example, an insulating contact is provided on the other surface of the charging plate facing the first gap, and the insulating contact is correspondingly provided with the connection contact. By providing this insulating contact, external short circuits can be avoided when the positive and negative electrodes of the battery come into contact with conductive materials during battery formation and placement of the battery to be tested, and electrical connections between two adjacent charging plates can also be prevented.

[0021] Optionally, the maximum thickness of the insulating strip is less than the height of the connection contact point relative to the charging plate. This design ensures sufficient contact between the charging plate's connection contacts and the electrodes of the battery under test during formation operations, thereby establishing a reliable connection.

[0022] Optionally, the edge of the insulating strip corresponding to the connecting contact point is sloped. This structural design ensures a smooth transition when the insulating strip opens and closes the connecting contact point.

[0023] Optionally, the connection point is a rectangular protrusion structure disposed on the surface of the charging plate. By designing the connection point as a rectangular protrusion structure, the reliability of the connection between the connection point and the electrode of the battery under test can be ensured during the formation operation.

[0033] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] The formation process of lithium batteries optimizes the interface between the electrolyte and electrodes, ensuring a stable ion transport path and improving battery conductivity and charge / discharge efficiency. However, external short circuits frequently occur during formation. For example, if the two electrodes of the battery come into contact with the same contact point on the charging plate during formation, a momentary short circuit can occur, generating excessively high charging voltage or current, causing serious safety issues. Avoiding external short circuits during lithium battery formation is a crucial measure to ensure production safety and quality. The formation cabinet according to this application can effectively prevent external short circuits during battery formation.

[0035] The following will combine Figure 1-6 The embodiments of this utility model will be described.

[0036] A formation cabinet according to one embodiment of this application includes a cabinet body 110, a plurality of charging plates 120, and an insulation assembly 130. The cabinet body 110 includes a cabinet base plate 1101 and cabinet side plates 1102, and a guide rail 111 is provided inside the cabinet. Figure 2 As shown, the cabinet contains multiple guide rails 111, including edge rails and guide rods. The charging plate 120 has corresponding guide grooves 121, which connect to the guide rails 111, allowing the charging plate 120 to be positioned perpendicular to the cabinet bottom plate within the cabinet 110. All charging plates 120 are parallel to each other, with a first gap between any two charging plates 120 for placing a battery 200 to be tested. The charging plate 120 can move on the guide rails 111, thereby adjusting the size of the first gap to accommodate batteries of different specifications. Each charging plate 120 has two connecting contact points 122 at each end, perpendicular to the direction of the guide rails and parallel to the bottom plate surface. Each end of the two connecting contact points 122 can connect to a battery 200 to be tested. These two connecting contact points at each end can be referred to as a connecting contact point pair. On the reverse side of the charging plate 120 (i.e., the other surface facing the first gap), an insulating contact 123 is provided at the position corresponding to the connection contact point 122. The insulating contact 123 is used to ensure that when the battery to be tested 200 is placed during battery formation, the positive and negative electrodes of the battery are prevented from contacting conductive materials and causing an external short circuit, and also to prevent electrical connection between two adjacent charging plates.

[0037] The insulating assembly 130 includes several insulating strips 131 and connecting guide rods 132. Two insulating strips 131 are provided between any two adjacent charging plates 120 (i.e., the first gap), respectively located at the connecting contacts 122 at both ends of the charging plate 120. Figure 1-2 As shown, the insulating strips 131 located at the same end of the charging plate 120 are connected in series by two connecting guide rods 132. The insulating strips 131 can slide together with the connecting guide rods 132 along a first predetermined direction under the drive of the connecting guide rods 132, thereby controlling the opening or closing of the connecting contact points of the insulating strips via the connecting guide rods 132. In this embodiment, the first predetermined direction can be any direction parallel to a surface of the charging plate facing the first gap that allows the opening or closing of the connecting contact points of the insulating strips; it is not limited here. In this embodiment, "connected in series" means that the connecting guide rods 132 connect different insulating strips 131 in a through-type manner, specifically as follows: Figure 2 As shown. During battery formation, the insulating strip 131 is first moved along a first predetermined direction to a first position by the connecting guide rod 132 to cover the connecting contact point 122 (as shown). Figure 5 As shown in the diagram, the connection contact point is closed. Then, the battery 200 to be tested is placed in the cabinet. This effectively avoids the risk of an external short circuit caused by both electrodes of the battery 200 simultaneously contacting the same connection contact point 122. After the battery 200 is fully placed in the cabinet, the insulating strip 131 is moved along the first predetermined direction to the second position via the connecting rod 132 to open (expose) the connection contact point 122, ensuring that the electrodes of the battery 200 are fully connected to the connection contact point 122. Then, a formation operation is performed on the battery. After formation, the insulating strip 131 is closed again via the connecting rod 132 to ensure that when the formed battery 200 is removed, the positive and negative electrodes of the battery will not simultaneously contact the same connection contact point, thus avoiding safety issues caused by short circuits. Furthermore, in the formation cabinet of this embodiment, the position of the charging plate 120 is set to be adjustable. After the battery to be tested 200 is completely placed into the cabinet and the insulating baffle 131 is driven to open the connection contact point 122 again by the connecting guide rod 132, the distance between the charging plates 120 can be adjusted by adjusting the position of the charging plate 120 so that the electrode of the battery to be tested and the connection contact point 122 are more fully contacted and connected.

[0038] According to one embodiment of this application, the two cabinet side panels 1102 parallel to the surface of the charging plate 120 facing the first gap, and all charging plates 120 are provided with first sliding holes 112 parallel to the surface of the cabinet bottom plate 1101. The height of the first sliding holes 112 is the same as the height of the connecting guide rod 132. The connecting guide rod 132 passes through the first sliding holes 112, and the charging plates 120 and insulating strips 131 are alternately connected in series on the connecting guide rod 132. The two side panels 1102 of the cabinet 110 are connected in series at both ends of the connecting guide rod 132 through the first sliding holes 112. When the connecting guide rod 132 slides along the first sliding holes 112, it drives the insulating strips 131 to open or close the connecting contact points 122. In a specific example, the connecting guide rod 132 is cylindrical, and the first sliding hole 112 is an oblong hole. By setting the connecting guide rod to a cylindrical shape and the first sliding hole to an oblong shape, the sliding of the connecting guide rod 132 within the first sliding hole 112 can be made smoother, facilitating the adjustment of the position of the insulating strip.

[0039] According to one embodiment of this application, the formation cabinet further includes an insulation component control mechanism, which is controlled to connect to the connecting guide rod 132 and drives the connecting guide rod 132 to slide within the first sliding hole 112. In this embodiment, the insulation component control mechanism can be implemented using various structures capable of driving the connecting guide rod 132 to slide within the first sliding hole 112, and is not limited thereto. Compared to manually adjusting the position of the connecting guide rod 132 within the first sliding hole 112 by moving it manually, this insulation component control mechanism makes adjusting the position of the connecting guide rod 132 within the first sliding hole 112 more convenient.

[0040] like Figure 1 and Figure 2 As shown, a specific exemplary insulation component control mechanism of this utility model includes two X-shaped brackets 140, which are symmetrically arranged on both sides of the cabinet. Figure 1 and Figure 2(The X-shaped bracket on the left side is not shown). Each X-shaped bracket 140 includes a first crossbar 141 and a second crossbar 142 pivotally connected together. Both ends of the first crossbar 141 and the second crossbar 142 are provided with second sliding holes 143. The first crossbar 141 and the second crossbar 142 are connected to the connecting guide rod 132 through the second sliding holes 143. The longitudinal direction (i.e., the length direction of the second sliding holes 143) at both ends of the first crossbar 141 is consistent with the length extension direction of the first crossbar 141. The longitudinal direction (i.e., the length direction of the second sliding holes 143) at both ends of the second crossbar 142 is consistent with the length extension direction of the second crossbar 142. Each end of the two X-shaped brackets is connected to the end of the connecting guide rod 132 through the second sliding hole 143. The insulation component control mechanism also includes a handle 1441 and a push rod (not shown in the figure). The push rod is connected to the handle 1441 and pivotally connected to any one of the connecting guide rods 132. The operation process is as follows: Push the push rod towards the center of the cabinet using handle 1441. The connecting guide rod, pivotally connected to the push rod, slides towards the center of the cabinet. Under the force of the connecting guide rod 132, the angle α of the X-shaped bracket increases. Consequently, the first and second cross rods 141 and 142 drive the remaining three connecting guide rods 132 to slide towards the center of the cabinet along the first sliding hole 112. Simultaneously, they slide relative to the first and second cross rods along the second sliding hole 143. The connecting guide rod 132 drives the insulating strip 131 to cover the connecting contact point 122. When the battery 200 to be tested is placed in, because the connecting contact point 122 is covered, the positive and negative terminals of the battery to be tested will not simultaneously contact the same connecting contact point 122, preventing a short circuit and avoiding safety issues caused by external short circuits. After all batteries are placed, pull handle 1441. The push rod pulls the connecting guide rod 132, which is pivotally connected to it. This, along with the X-shaped bracket, causes the other connecting guide rods 132 to slide towards the edge of the cabinet, opening the connection contact point 122 and connecting the positive and negative terminals of the battery to it. After formation is complete, push handle 1441 again. Driven by the push rod, X-shaped bracket, and connecting guide rod 132, the insulating barrier 131 closes the connection contact point. When the battery to be tested is removed, its positive and negative terminals will not simultaneously contact the same connection contact point 122, thus preventing a short circuit. This insulating component control mechanism, including two X-shaped brackets, features a simple structure, high reliability, and low cost.

[0041] According to another embodiment of this application, the thickness of the insulating strip 131 (i.e., the distance between the two ends of the insulating strip in the direction perpendicular to the charging plate) is slightly lower than the height of the connection contact 122 relative to the charging plate 120 (i.e., the height of the connection contact in the direction perpendicular to the charging plate). When the insulating strip 131 is opened, it can ensure that the two poles of the battery under test are fully connected to the connection contact 122. Further, the edge of the insulating strip 131 corresponding to the connection contact is sloped (see...). Figure 6 This allows for a smooth transition when opening and closing contact points.

[0042] The above descriptions are merely some specific embodiments of this application. In other embodiments, variations or modifications can be made to the various components. For example, the charging board may have two connection electrodes at only one end, in which case one charging board can only be used to perform formation operations on one battery at a time. As another example, the connecting rods may be cuboid structures or other suitable structures, and correspondingly, the shapes of the first sliding hole and the second sliding hole are adapted to the shape of the connecting rods. Furthermore, the number of connecting rods at one end of the charging board can be... Figure 2 The two shown in the embodiment can also be one, three, or any other feasible number.

[0043] According to the formation cabinet of this application embodiment, by setting an insulating component, that is, setting an insulating strip between two adjacent charging boards, and controlling the opening or closing of the connecting contacts on the charging board by connecting guide rods, the connecting contacts can be closed during the battery loading and unloading process, avoiding the positive and negative terminals of the battery under test from contacting the same connecting contact point at the same time, which would cause an external short circuit in the battery, thereby effectively avoiding serious heat and safety problems caused by rapid battery discharge.
