The operating state of the power battery directly affects the operating conditions of the mobile device. An important factor affecting the performance of the power battery is the temperature of the power battery. When the power battery is working, the battery generates a large amount of heat under high-rate discharge, which causes the temperature of the battery itself and the surrounding environment to rise rapidly. The high temperature environment will reduce the battery work efficiency, affect the battery power output and even burn the battery, causing hidden dangers. In order to improve the heat dissipation efficiency of the power battery, people will put the solid-liquid phase heat-conducting material into the power battery, and absorb the heat generated by the power battery through the phase change of the heat-conducting material.
然而,由于要满足电芯之间串联的需求,传统的动力电池的壳体上通常会设置有供多个电芯的极耳穿设或收容的部位,导致所述动力电池的密封性不佳。当所述固液相变导热材料在其温度升高达到一定值时,会产生固态-液态的转换,其容易自所述动力电池的壳体内渗漏,造成安全隐患。However, due to the need to meet the series connection between the cells, the housing of the conventional power battery is usually provided with a portion for the tabs of the plurality of cells to be worn or received, resulting in poor sealing of the power battery. . When the solid-liquid phase change heat conductive material reaches a certain value when its temperature rises, a solid-liquid transition occurs, which easily leaks from the casing of the power battery, posing a safety hazard.
