AI Technical Summary

Technical Problem

The welding process of existing battery cells is prone to causing the insulating material to melt through, which affects the safety and sealing performance of the battery. In addition, the traditional welding process is cumbersome and reduces the energy density of the battery.

Method used

A support structure is set between the pole base plate and the insulation component to act as a heat buffer layer to absorb welding heat, and a three-dimensional structure is used to form a heat-barrier cavity to ensure that gas can diffuse to the sealing ring installation area, thus achieving efficient and reliable welding.

Benefits of technology

This effectively avoids the problem of insulation material melting through, improves welding speed and the accuracy of sealing inspection, and enhances battery safety and energy density.
