Abstract

Taking into account of high energy density and safety, solid-state lithium-ion batteries (LIBs) are promising for next-generation energy storage devices and high-performance power sources, and the inorganic solid electrolyte is a key component in LIBs. Here, a new system of solid oxide electrolyte with a nominal composition of Li29Zr9Nb3O40 (LZNO) and Al-doped LZNO are prepared through a sol-gel method and the related ionic conductivities are firstly investigated. All the prepared compounds have an orthorhombic structure. The pure LZNO shows a bulk conductivity of 1.75
