AI Technical Summary

⚠Technical Problem

The battery tabs are prone to overlapping with the terminals, which affects the welding quality between the terminals and the adapter, leading to poor or incomplete soldering and affecting battery performance and safety.

⚗Method used

A protrusion is designed on the adapter plate, facing the pole, to block the extension of the tab and prevent the tab from interfering with the welding point between the pole and the adapter plate, ensuring that the tab is welded in the correct position.

🎯Benefits of technology

Reduce the occurrence of incomplete or poor welding, improve welding stability and consistency, reduce welding defects and overheating risks, and enhance the electrical performance and safety of batteries.

Abstract

The application provides a battery and a power utilization device. The battery comprises a shell with a receiving cavity, a pole is arranged on the shell; a battery cell is located in the receiving cavity, the battery cell has a tab; a transition piece is located between the pole and the battery cell, the transition piece has a first surface, the first surface faces the pole, and the tab is connected to the first surface; a protrusion is arranged on the transition piece, the protrusion is located on the first surface and protrudes towards the pole, and the projection of the protrusion and the projection of the pole at least partially coincide in the thickness direction of the battery. The application avoids virtual welding, thereby improving the electrical performance and safety of the battery.
