| Zusammenfassung: | The utility model provides a battery cell and power equipment, the battery cell comprises a shell, a pole group body and a cover plate, at least one end of the shell is provided with an opening, the pole group body is accommodated in the shell, the cover plate is used for blocking the opening, an explosion-proof device is arranged on the cover plate, and an insulating heat-conducting layer is filled between the pole group body and the shell. And the insulating heat-conducting layer is provided with an exhaust channel which is arranged along the length direction of the pole group body in a penetrating manner. According to the battery cell disclosed by the utility model, the insulating heat-conducting layer is filled between the periphery of the pole group body and the shell, so that the heat dissipation effect of the pole group body is improved, the temperature of the pole group body is reduced, the probability of thermal runaway of the battery cell is reduced, and the safety performance of the battery cell is |
