Intermetallic lithium compounds with two‐ and three‐dimensional polyanions—synthesis, structure, and lithium mobility

Abstract

Abstract Intermetallic lithium compounds are potential candidates as anode materials for battery applications. We report on the synthesis, crystal structures, and chemical bonding of lithium–transition metal–stannides and indides. These structures are composed of two‐ or three‐dimensionally infinite polyanions formed by the transition metal and tin (indium) atoms. Besides the crystal chemistry we report on magnetic properties, 7 Li solid state NMR, and 119 Sn Mössbauer spectroscopy data in order to elucidate structure‐property relations for this family of intermetallics. © 2002 Wiley Periodicals, Inc.
