The invention discloses a battery module capable of delaying heat diffusion, which comprises a module body; the module body comprises at least two battery cells and a heat insulation plate, the heat insulation plate is clamped between two adjacent battery cells, each battery cell comprises a battery cell body and a tab, and the heat insulation plate extends out of the battery cell body and at least shields part of the tab. According to the battery module, the heat insulation plate extends out of the battery cell body and shields part of the tabs, and the area, covering the battery cells, of the heat insulation plate is increased, so that the heat radiated by the thermal runaway battery cells to the adjacent battery cells is reduced, the other battery cells are protected, heat diffusion iseffectively delayed, and the safety of the battery module is improved. 本发明公开一种可延缓热扩散的电池模组，包括模组本体，模组本体包括电芯和隔热板，电芯设置有至少两个，相邻两个电芯之间夹设隔热板，电芯包括电芯本体以及极耳，隔热板延伸出电芯本体外并至少遮挡部分极耳。将隔热板延伸出电芯本体外并遮挡部分极耳，通过增大隔热板对电芯覆盖的区域，减少热失控的电芯向相邻的电芯辐射的热量，对
