AI Technical Summary
The connecting piece cannot effectively dissipate heat during the charging and discharging process of the battery cell, especially when the temperature rises significantly during high-rate charging and discharging, resulting in low charging and discharging capacity of the battery cell.
A thermally conductive colloid is placed between the grooves of the connecting piece and the cover plate. The heat generated by the connecting piece is conducted to the protrusions of the cover plate through the thermally conductive colloid, and the heat is transferred to the outside through the protrusions of the cover plate. At the same time, the thermally conductive colloid is placed between the cover plate and the connecting piece to ensure the stability of the heat conduction path.
It achieves effective heat dissipation of the connecting piece, improves the battery cell's ability to charge and discharge at high rates, and prevents the thermally conductive colloid from contaminating other areas through insulation, ensuring the stability of the heat conduction path.
