微胶囊阻燃型复合相变材料在电池热安全中的机理研究
Experimental study on composite flame-retardant microencapsulated phase change materials for battery thermal management
摘要
Abstract
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.关键词
