Experimental study on composite flame-retardant microencapsulated phase change materials for battery thermal management
开发了一种兼具高导热性、阻燃性与结构稳定性的阻燃复合相变材料,用于动力电池热管理.以聚乙二醇为基体,三聚氰胺氰尿酸盐微胶囊化磷酸三苯酯作阻燃剂,膨胀石墨增强导热,环氧树脂提升力学强度.实验表明,当膨胀石墨添加量为3%、微胶囊阻燃剂含量为29%时,PEE/MTPP2性能优异.在1 C、2 C、3 C放电倍率下,电池最高温度分别为33.5、42.6和48.8℃,最大温差分别为0.3、1.0和0.5℃,控温均温效果良好,为动力电池热管理提供了高性能安全方案,在新能源汽车等领域应用前景广阔.
A flame-retardant composite phase change material with high thermal conductivity,flame retardancy,and structural stability was developed for power battery thermal management.Polyethyl-ene glycol served as the matrix,while melamine cyanurate microencapsulates triphenyl phosphate as the flame retardant.Expanded graphite enhanced thermal conductivity,and epoxy resin improved mechanical strength.Experiments show that with 3%expanded graphite and 29%microencapsu-lated flame retardant,PEE/MTPP2 demonstrates excellent performance.Under 1 C,2 C,and 3 C dis-charge rates,the battery's maximum temperatures are 33.5,42.6,and 48.8℃,with maximum tem-perature differences of 0.3,1.0,and 0.5℃,respectively.This material offers a high-performance and safe solution for power battery thermal management,with promising application prospects in new en-ergy vehicles and other fields.
