AI Technical Summary
In existing technologies, the width of the electrode post is relatively large, which is not suitable for battery cells with small thickness. This results in weak overcurrent capacity, affecting the battery's charge and discharge performance and safety performance, and increasing the difficulty of processing.
A pole post is designed, including at least one first connecting part, at least two second connecting parts, and a transition part. The transition part is connected between the first connecting part and the second connecting part. The length of the transition part is less than the length of the first connecting part and the second connecting part. By optimizing the structure of the pole post to adapt to the limited design space of the top cover assembly, the current carrying capacity and safety performance are improved.
The size of the electrode post in the width direction was reduced, the welding surface width was increased, the current flow area of the battery was optimized, the safety performance of the battery was improved, and the processing difficulty was reduced.
