New P2-Type Honeycomb-Layered Sodium-Ion Conductor: Na 2 Mg 2 TeO 6

A novel solid sodium-ion conductor, Na Mg TeO (NMTO) with a P2-type honeycomb-layered structure, has been synthesized for the first time by a simple solid-state synthetic route. The conductor of NMTO exhibits high conductivity of 2.3 × 10 S cm at room temperature (RT) and a large electrochemical win...

Description
Summary:A novel solid sodium-ion conductor, Na Mg TeO (NMTO) with a P2-type honeycomb-layered structure, has been synthesized for the first time by a simple solid-state synthetic route. The conductor of NMTO exhibits high conductivity of 2.3 × 10 S cm at room temperature (RT) and a large electrochemical window of ∼4.2 V (versus Na /Na). The conductor is remarkably stable, both in the ambient environment and within its metallic Na anode. This facile sodium-ion conductor displays potential for use in all-solid-state sodium-ion batteries (SS-SIBs).
