外文摘要：It is of significance to construct continuous multiphase percolation channels with fast lithium-ion pathway in hybrid solid electrolytes.3D ceramic nanostructure frameworks have attracted great attention in this field.Herein,the three-dimensional perovskite Li0.33La0.557TiO3 nanotubes framework(3D-LLTO-NT)is fabricated via a facile coaxial electro-spinning process followed by a calcination process at 800 ℃.The hybrid polymer electrolyte of 3D-LLTO-NT framework and poly(ethylene carbonate)(3D-LLTO-NT@PEC)shows improved ionic conductivity of 1.73 × 104 S cm-1 at ambient temperature,higher lithium-ion transference number(tLi+)of 0.78 and electrochemical stability window up to 5.0 V vs Li/Li+.The all-solid-state cell of LiFePO4/3D-LLTO-NT@PEC/Li delivers a high specific capacity of 140.2 mAh g-1 at 0.1 C at ambient temperature.This outstanding performance is attributed to the 3D ceramic nanotubes frameworks which provide fast lithium ion transfer pathway and stable interfaces.
