中文摘要	P(acrylonitrile-methyl methacrylate)[P(AN-MMA)] was synthesized by emulsion polymerization method. The P(AN-MMA) copolymer microporous membrane composited SiO/sub 2/ was prepared by in situ composition and phase inversion methods. The P(AN-MMA) gel electrolyte was obtained by soaking with electrolyte. The porous size of this membrane was 1 ~ 5 mu m, the porosity was 70% , the thermal stability was fine. Compared with the membrane without composited SiO/sub 2/, the tensile performance of this membrane in situ composited SiO/sub 2/ was improved. The button cell with LiFePO/sub 4/ as working electrode, lithium tablet as counter electrode and the P(AN-MMA) gel electrolyte in situ composited SiO/sub 2/ was assembled.Its specific discharge capacity and discharge efficiency at the initial cycle were 148.2 mAh/g and 84.4%. The specific discharge capacity was 132.2 mAh/g and the capacity retention was 89.2% at the 95th cycle.
