Atomic-resolution STEM-EDS studies of cation ordering in Ti-Nb oxide crystals

Abstract Ternary metal oxide compounds, such as Ti-Nb and Nb-W oxides, have renewed research interest in energy storage materials because these oxides contain multivalent metal ions that may be able to control the ion transport in solid lithium batteries. One of these oxides is Ti2Nb10O29, which is...
