摘　　要：研究了聚合物锂离子电池软包装用轻薄铝塑复合膜的热封条件。根据复合膜内层聚丙烯(PP)的DSC曲线、热封后封印处的PP状态及PP间的剥离力,得出当热封86μm厚的复合膜时,封头温度为170℃、时间为3 s,效果最好。Heat-sealing parameter of thin aluminum laminated foil for soft pack polymer Li-ion battery was studied. Based on the DSC curve of polypropylene（PP） of laminated foil inner layer,PP status of seal after heat sealing and peel strength between PP,it was found when hot sealing laminate foil with thickness of 86 μm,the optimum hot sealing temperature was 170 ℃ and time was 3 s.
