Na3 Co2 Sb1 O6

Na₃Co₂SbO₆ is a layered sodium cobalt antimonite oxide semiconductor, synthesized as a research compound in the broader family of mixed-metal oxides and double perovskites. This material is being investigated for electrochemical energy storage and conversion applications, particularly as a potential cathode material or electrochemically active phase due to its complex layered structure and mixed-valence transition metal chemistry. The compound exemplifies the ongoing research into sodium-based alternatives to lithium-ion systems, offering potential cost and abundance advantages, though it remains primarily in the experimental stage with properties and performance still under characterization.
