[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the increasing popularity and application of electric vehicles, power batteries as power energy storage devices are gaining more and more attention. The main power batteries currently used are square aluminum shell batteries. In the process of developing square aluminum shell batteries, it is often necessary to disassemble and analyze the batteries to conduct in-depth research on the evolution of the physical and chemical properties of the positive electrode, negative electrode, electrolyte and diaphragm. Therefore, the disassembly effect of lithium-ion batteries will directly affect the accuracy of subsequent data analysis.

[0004] Currently, the main way to disassemble square aluminum shell batteries is to disassemble the battery shell and take out the internal core for analysis. During the disassembly process, a ceramic knife is first used to cut the battery shell, and then pliers and other tools are used to tear the battery shell along the opening to take out the core. Since the core is wrapped with electrolyte, active substances and other materials, heavy metals such as lead, lithium, nickel and organic solvents may be exposed to harmful substances during the disassembly of the battery shell using only ceramic knives, pliers and other tools. In addition, improper disassembly methods may lead to extreme situations such as explosions and fires. Therefore, the above disassembly methods are neither safe nor efficient. Utility Model Content

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] Example 1

[0029] In a typical implementation of the present invention, Figure 1 As shown, a square aluminum shell battery disassembly auxiliary tool is provided, including a base, a battery accommodating groove 2 and a battery accommodating top cover 1, wherein the battery accommodating groove 2 is fixed on the base, a square aluminum shell battery is placed in the battery accommodating groove 2, and the battery accommodating top cover 1 is placed on the upper part of the square aluminum shell battery, the upper surface of the battery accommodating groove 2 and the lower surface of the battery accommodating top cover 1 are separated by a certain distance, a notch is provided at the center position of the long side of the battery accommodating top cover, and the contour line formed by the battery accommodating top cover on the square aluminum shell battery is used as the marking trajectory.

[0030] In this embodiment, the width and length of the battery accommodating groove 2 match the length and width of the square aluminum shell battery, so that the square aluminum shell battery can be placed in the battery accommodating groove, and the height of the battery accommodating groove is less than the height of the square aluminum shell battery. Specifically, the height of the battery accommodating groove is less than half the height of the square aluminum shell battery, so that the upper half of the square aluminum shell battery can be exposed from the battery accommodating groove, so as to facilitate the cutting of the square aluminum shell battery.

[0031] In this embodiment, the length and width of the battery housing cover 1 match the length and width of the square aluminum shell battery. Figure 2 and Figure 3 As shown, the battery containing top cover 1 is formed by connecting two right-angled triangle shells, and the notch 6 is located at the position where the two right-angled triangle shells are connected.

[0032] Furthermore, two notches 6 are provided, respectively located at the center positions of the two long sides on the upper surface of the battery containing top cover, the shape of the notch is semicircular, the height of the highest point of the battery containing top cover is less than one quarter of the height of the square aluminum shell battery, and when the battery containing top cover 1 is placed on the upper part of the square aluminum shell battery, the position of the square aluminum shell battery located between the battery containing top cover 1 and the battery containing groove 2 can be exposed, so that the battery shell can be cut open with a ceramic knife.

[0033] Furthermore, the top surface of the battery containing top cover 1 is provided with two rectangular grooves 5, and an insulating sheet is attached to the rectangular grooves. The two rectangular grooves 5 correspond to the positive electrode column and the negative electrode column of the square aluminum shell battery respectively, so that when the battery containing top cover is placed on the top of the square aluminum shell battery, the battery containing top cover is fixed to prevent the battery containing top cover from shifting when marking.

[0034] In this embodiment, the two long sides of the upper surface of the battery accommodating groove 2 are arc-shaped structures, which increases the wrapping area of ​​the battery accommodating groove 2 for the square aluminum shell battery and improves the stability when the shell of the square aluminum shell battery is cut open.

[0035] In this embodiment, the base includes a bottom plate 4 and two slide plates 3 sleeved on the bottom plate, and the battery accommodating groove 2 is placed on the bottom plate 4 and is clamped and fixed by the two slide plates 3 .

[0036] The method of using the square aluminum shell battery disassembly auxiliary tooling provided in this embodiment is as follows:

[0037] Place the battery accommodating groove 2 on the bottom plate 4 and clamp it with two slides 3, put the battery into the battery accommodating groove 2, and then place the battery accommodating top cover 1 on the top of the battery, use a ceramic knife to cut a notch at the center notch position on the battery accommodating top cover 1, then scratch along the edge of the triangle, remove the battery accommodating top cover 1, use pliers to open the aluminum shell from the notch along the scratched line, then take the battery cell out of the aluminum square shell, and then take the aluminum square shell out of the groove to complete the preliminary disassembly.

[0038] Compared with the method of marking along the width of the battery or marking by hand, the utility model makes an innovation in the marking trajectory. The trajectory is to cut a small notch at the center point of the top of the two large surfaces of the battery and then mark the aluminum square shell along the shape of the battery housing top cover. This marking trajectory reduces the probability of the aluminum shell being easily broken during disassembly and improves the disassembly efficiency.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
