Abstract
The utility model discloses a pole space ring, battery cell, battery pack and electric equipment, pole space ring includes heat storage part and insulating heat conduction layer, heat storage part is used for absorbing the heat of the tab of naked battery cell to reduce the temperature of tab during electric conduction, the insulating heat conduction layer is covered outside the heat storage part, and the insulating heat conduction layer is covered outside the heat storage part. The insulating heat-conducting layer is suitable for being in heat conduction contact fit with the tab of the naked battery cell. The pole space ring can absorb heat at the tabs and conduct the heat out, so that the temperature of the whole structure of the naked battery cell is uniform, the heat dissipation problem of the single battery is improved, the use safety and the use performance of the battery cell are improved, and the service life of the battery cell is prolonged.
