New Lithium Ion Conductor Li3InBr6 Studied by 7Li NMR

Abstract Super ionic conductor Li3InBr6 (σ=10−3Scm−1 at 297 K) due to lithium ions was synthesized and characterized by temperature dependence of the 7Li NMR T1. The substitution effect of the cation and the temperature behavior of T1 suggested that the high ionic conductivity resulted from the considerably disordered state of the cationic sublattice.
