Abstract: A thermal management device and a battery pack are provided. The thermal management device applied in a battery pack. The battery pack includes a case and a plurality of cells received in the case. The thermal management device includes: a thermal management loop attached to each cell and at least partially covering a part of a vent of each cell; a heat exchange member communicating with the thermal management loop; and a power component connected between the thermal management loop and the heat exchange member. A heat exchange medium with a fire-extinguishing function is provided within the thermal management loop. The thermal management loop is broken in a condition where at least one cell is subjected to thermal runaway such that the heat exchange medium flows into an explosion-proof port of the at least one cell.

Abstract: This application relates to a heating assembly, a battery, and an electrical device. A heating sheet is affixed to a surface of a battery cell to heat the battery cell. When the battery cell thermally expands, cracks can break under an expansion force of the battery cell, so that the heating sheet deforms synchronously with the battery cell to prevent the heating sheet from being detached from the battery cell, thereby improving the efficiency of the heating sheet in heating the battery cell.

Abstract: The present application relates to the technical field of batteries, and in particular to a current collector, an electrode sheet, an electrode assembly, a battery cell, a battery and an electric apparatus. The current collector includes: a support layer; and a conductive layer on at least one of two opposite sides of the support layer, where when the support layer is heated and shrinks, the conductive layer shrinks with the support layer to form a hole around a heated portion, the conductive layer includes a first conductive layer in contact with the support layer, and the first conductive layer is a granular conductive layer. On this basis, the safety performance can be improved.

Abstract: The present application provides a heatable battery pack, a heatable battery system and a vehicle having thereof. The heatable battery pack includes a battery, a first switch module, and a heater that are connected in series to form a heating loop. The first switch module turns on the heating loop after a drive signal is received. Compared with the related art in which heaters in various battery packs are connected in series to both ends of a drive module in a high-voltage box, so as to perform high-voltage power supply on the heaters by the high-voltage box through a series loop, the present application directly performs low-voltage power supply on respective heaters by batteries in the battery packs, and the high-voltage power supply by the drive module is not required, which significantly improves the safety of power supply.
