【摘要】：以负载Al_2O_3的无纺布为支撑膜,浸涂PEO-LAGP-SN-Li TFSI的乙腈共混液干燥后制得新型复合固态电解质膜(CLASP)。该膜的热稳定性好,即使在170℃的高温下依然不发生形变。当浸涂共混液中PEO:LAGP:SN:Li TFSI为3:1:1:1,固含量为10wt%时,室温电导率可以达到3.66×10~(-5) S/cm,100℃时电导率可达2.52×10~(-4) S/cm.CLASP膜的电化学窗口宽,以该膜代替液态电解质装配的全固态LiFePO_4/CLASP/Li电池,在55℃循环时表现出良好的循环稳定性,高的库伦效率,有望成为电化学性能优越的全固态电解质。
[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，
