December 2011The figure shows a part of the crystal structure of Li7La3Zr2O12 garnet (LLZO), showing the 3D connected channels responsible for Li+-transport in LLZO. The 3D-connected space consists of interstitial octahedral sites (yellow) sharing two opposite faces with neighbouring “LiO4” tetrahedral sites (orange). The inset shows LLZO grains with a novel Li+-conducting phase in the grain boundaries. The interfacial Li+-conducting phase enhances the Li+-conductivity of LLZO, reaching a value of 5.4 ⋅ 10−4 S⋅cm−1 at 20 °C. Since August 2011 Dr. Hany El-Shinawi works as Fellow of the Alexander-von-Humboldt Foundation at the Institute of Physical Chemistry in the group of Prof. Janek. Dr. El-Shinawi studied chemistry at the Mansoura University in Egypt and obtained his PhD at the University of Birmingham. He is a specialist in the preparation and characterization of functional oxides and currently studies a number of solid lithium-ion conductors. As a member of the solid-electrolyte team in Prof. Janek group, Dr. El Shinawi is particularly trying to develop and characterize novel garnet-type lithium electrolytes. The study also aims to optimize the structural and electrochemical properties of these garnets for their use as electrolytes in all-solid-state batteries.
