The invention provides a heat insulation assembly and a battery, and belongs to the technical field of batteries. The heat insulation assembly comprises a frame and a heat insulation unit arranged on the frame; the heat insulation unit is of a sealed bag-shaped structure, the heat insulation unit is arranged in the frame, and the edge of the heat insulation unit is connected to the frame; the heat insulation unit is filled with a flowing heat insulation material and can absorb heat generated by the battery cell; the heat insulation unit located in the frame is provided with at least one sunken area, the sunken area is expanded after being heated, and the surface of the expanded sunken area protrudes outwards. According to the heat insulation assembly and the battery provided by the invention, the heat insulation assembly expands when being heated, so that the thermal runaway battery cells can be effectively isolated, the heat insulation performance among the battery cells is improved, and the thermal runaway phenomenon of the whole battery is avoided.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a heat insulation component and a battery. Background technique [0002] With the rise of electric vehicles, the safety of automotive batteries has gradually become the focus of attention, among which the risk of thermal runaway has attracted attention, so how to reduce the thermal runaway of batteries has become a research hotspot. [0003] At present, the means to prevent thermal runaway of the battery is: adding heat insulating material between the cells in each battery module, and setting the above heat insulating material between each battery module or above the battery module, To protect the entire battery from thermal runaway. The heat insulation material can be airgel felt, mica board, ceramic pad and other materials or composite materials. [0004] However, when the heat insulation layer made of the above heat insulation material is used to protect the battery from h...
