【摘要】：以負(fù)載Al_2O_3的無紡布為支撐膜,浸涂PEO-LAGP-SN-Li TFSI的乙腈共混液干燥后制得新型復(fù)合固態(tài)電解質(zhì)膜(CLASP)。該膜的熱穩(wěn)定性好,即使在170℃的高溫下依然不發(fā)生形變。當(dāng)浸涂共混液中PEO:LAGP:SN:Li TFSI為3:1:1:1,固含量為10wt%時,室溫電導(dǎo)率可以達(dá)到3.66×10~(-5) S/cm,100℃時電導(dǎo)率可達(dá)2.52×10~(-4) S/cm.CLASP膜的電化學(xué)窗口寬,以該膜代替液態(tài)電解質(zhì)裝配的全固態(tài)LiFePO_4/CLASP/Li電池,在55℃循環(huán)時表現(xiàn)出良好的循環(huán)穩(wěn)定性,高的庫倫效率,有望成為電化學(xué)性能優(yōu)越的全固態(tài)電解質(zhì)。
[Abstract]:A novel composite solid-state electrolyte membrane (clasp) was prepared by drying the acetonitrile blend solution of PEO-LAGP-SN-Li TFSI with the non-woven Al2O3 bearing fabric as the supporting membrane. The film has good thermal stability and does not deform even at 170 鈩，
