摘要：

Polymer/garnet solid oxide composite electrolyte has been regarded as a promising solution for solid-state lithium metal battery. It has many advantages such as higher flexibility, lower density, relatively higher ionic conductivity and better contact with electrodes as compared to pure oxide electrolytes and pure polymer electrolytes. In this work, we report a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) / Li6.4La3Zr1.4Ta0.6O12 (LLZTO) composite electrolyte with a facile synthesis route and all commercially available raw materials. This hybrid electrolyte exhibits overall outstanding properties, including wide electrochemical stability window (similar to 5 V), superior mechanical properties with tensile strength over 13 MPa and Young's Modulus >50 MPa, relatively good room temperature ionic conductivity (3.2 x 10(-4) S.cm(-1)) and good electrochemical performance (similar to 150 mAh g(-1) at 0.1C and 99% coulombic efficiency after 50 cycles).
