摘要：

An all solid-state lithium-ion battery with high energy density and high safety is a promising solution for a next-generation energy storage system. High interface resistance of the electrodes and poor ion conductivity of solid-state electrolytes are two main challenges for solid-state batteries, which require operation at elevated temperatures of 60-90 degrees C. Herein; we report the facile synthesis of Al3+/Nb5+ codoped Cubit Li2La3Zr2O12 (LLZO) nanoparticles and LLZO nano particle decorated porous carbon foam (LLZO@C) by the onestep Pechini sol-gel method. The. LLZO nanoparticle-filled poly(ethylene oxide) electrolyte shows Unproved conductivity compared with filler-free samples. The sulfur composite cathode based on LLZO@C can deliver an attractive specific capacity of >900 mAh g(-1) at the human body teniperature 37 degrees C and a high capacity of 1210 and 1556 mAh g(-1) at 50 and 70 degrees C, respectively. In addition, the solid-state Li-S batteries exhibit high Coulombic efficiency and show remarkably Stable cycling performance.
