主　　题：quasi solid state electrolytes Li1.4Al0.4Ti1.6(PO4)3 conductivities 

摘      要：The composite quasi solid state electrolytes（CQSE） is firstly synthesized with quasi solid state electrolytes（QSE） and lithium-ion-conducting material Li1.4Al0.4Ti1.6（PO4）3（LATP）, and the QSE consists of [LiG4][TFSI] with fumed silica nanoparticles. Compared with LATP, CQSE greatly improves the interface conductance of solid electrolytes. In addition,it has lower liquid volume relative to QSE. Although the liquid volume fraction of CQSE is droped to 60%, its conductivity can also reach 1.39 × 10^-4S/cm at 20℃. Linear sweep voltammetry（LSV） is conducted on each composite *** results show the possibility that CQSE has superior electrochemical stability up to 5.0 V versus Li/Li^＋1. TG curves also show that composite electrolytes have higher thermal stability. In addition, the performance of Li/QSE/Li Mn2O4 and Li/CQSE/Li Mn2O4 batteries is evaluated and shows good electrochemical characteristics at 60℃.
