摘　　要：制备了一种具有超薄、高吸液率和良好热稳定性的Li/SOCl_2电池用聚酰亚胺(PI)/聚四氟乙烯(PTFE)复合隔膜。通过SEM、同步热分析(STA)、吸液率及恒电流放电等方法,研究PI、玻璃纤维(GF)和PTFE隔膜的结构、热稳定性和吸液性能,以及复合隔膜对Li/SOCl_2电池输出电压的影响。相对于采用GF/GF隔膜的电池,采用PI/PTFE复合隔膜的电池输出电压提升了0.130 V,热生成速率降低了39.4%。A polyimide （PI）/polytetrafluoroethylene （PTFE） composite membrane for Li/SOC12 battery was made, which was a ultra thin membrane with high absorption rate and good thermal stability. The structure, thermal stability and electrolyte uptake property of PI, glass fiber（GF） and PTFE membranes and effect of composite membrane on output voltage of Li/SOC12 battery were studied by simultaneous thermal analysis （ STA）, SEM, electrolyte uptake and galvanostatic discharge experiments. In comparison with the battery using GF/GF membrane, the output voltage of the battery using PI/PITE composite membrane was raised 0. 130 V, the heat generation rate was reduced 39. 4%.
