Abstract
Several research activities have been focused towards using lithium-ion batteries to act as an all solid-state battery. This requires a highly lithium-ion conducting solid to play the role of a solid electrolyte. This has been a major barrier towards the realization of a high efficiency all solid-state lithium-ion battery, which is why our research is focused on discovering new materials that can potentially serve as a solid state lithium electrolyte. We have synthesized a lithium-borate composition and solved the structure using single-crystal x-ray diffraction. The structure of this compound, Li3B5O8(OH)2, crystallizes in the Pnc2 space group, indicates good lithium-ion conduction and is built with BO3 and BO4 polyhedra and forms a layered topology. This project details the synthesis, structure, powder X-ray diffraction, and IR and NMR spectroscopic characterization as well as lithium-ion conduction measurements of the new composition.
