[0068] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the workpiece 20 is an electrode assembly. The electrode assembly includes a main body 21, a first pole ear 22 and a second pole ear 23. The first pole ear 22 and the second pole ear 23 have opposite polarities, and the first pole ear 22 and the second pole ear 23 protrude from the same end of the main body 21 along the first direction. The plurality of protrusions include a first protrusion 123 and a second protrusion 124 arranged opposite to each other along the first direction. A resisting block 1231 is provided on one side of the first protrusion 123 facing the second protrusion 124. The resisting block 1231 is used to resist and position the main body 21 together with the second protrusion 124. Along the second direction, a first avoidance groove 1232 and a second avoidance groove 1233 are formed on both sides of the resisting block 1231, respectively. The first avoidance groove 1232 is used to avoid the first pole ear 22, and the second avoidance groove 1233 is used to avoid the second pole ear 23. The second direction intersects with the first direction.

[0069] The electrode assembly is the part in the battery cell where the electrochemical reaction occurs. A battery cell may contain one or more electrode assemblies. The electrode assembly is mainly formed by winding or stacking the positive electrode sheet and the negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet.

The positive pole ear and the negative pole ear may be located together at one end of the main body. During the charge and discharge process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte.

[0070] The polarities of the first pole tab 22 and the second pole tab 23 are opposite. When the first pole tab 22 is a positive pole tab, the second pole tab 23 is a negative pole tab. When the first pole tab 22 is a negative pole tab, the second pole tab 23 is a positive pole tab.

[0071] The first electrode tab 22 and the second electrode tab 23 are located at the same end of the main body 21 along the first direction. Figure 1 , Figure 2 and Figure 3 , the first direction is the X direction shown in the figure.

[0072] The first protrusion 123 and the second protrusion 124 are arranged opposite to each other along the first direction.

[0073] Please refer to Figure 1 , Figure 2 and Figure 3 , the second direction may be the Y direction shown in the figure. In the embodiment shown in the figure, the second direction is perpendicular to the first direction.

[0074] A first avoidance groove 1232 and a second avoidance groove 1233 are respectively formed on both sides of the abutting block 1231 along the second direction, wherein the first avoidance groove 1232 can avoid the first pole ear 22, and the second avoidance groove 1233 can avoid the second pole ear 23. Optionally, the size of the first avoidance groove 1232 is larger than the size of the first pole ear 22, so that the first pole ear 22 does not contact the groove side wall of the first avoidance groove 1232 when it is accommodated in the first avoidance groove 1232. The size of the second avoidance groove 1233 is larger than the size of the second pole ear 23, so that the second pole ear 23 does not contact the groove side wall of the second avoidance groove 1233 when it is accommodated in the second avoidance groove 1233.

[0075] The abutting block 1231 can not only abut the positioning main body 21 together with the second protrusion 124, thereby limiting the movement of the main body 21 and realizing the positioning of the electrode assembly, but also play a separating role, thereby separating the first pole ear 22 and the second pole ear 23, so that the first pole ear 22 and the second pole ear 23 are respectively accommodated in the first avoidance groove 1232 and the second avoidance groove 1233, thereby reducing the risk of short circuit caused by the overlap of the first pole ear 22 and the second pole ear 23.

[0076] The main body 21 includes a plurality of corner portions 24 . The first avoidance groove 1232 can avoid one corner portion 24 , and the second avoidance groove 1233 can avoid another corner portion 24 .
