description A high voltage battery module includes a plurality of battery cells, a plurality of cooling fins dispersed between the battery cells, and a frame for holding the plurality of battery cells and the plurality of fins. An intumescent layer is proximate to at least one battery module component selected from the battery cells, the plurality of cooling fins, and the frame. The intumescent layer includes sodium silicate having formula Na2SiO3, pentaerythitol, a resin that is cross-linked by melamine, boron nitride particles, and triammonium phosphate. 种高压电池模块包括多个电池单元、分散在电池单元之间的多个冷却片以及用于保持多个电池单元和多个片的框架。膨胀层邻近选自于电池单元、多个冷却片和框架的至少个电池模块部件。膨胀层包括分子式为NaSiO的硅酸钠、季戊四醇、三聚氰胺交联的树脂、氮化硼颗粒以及磷酸三铵。
