Summary
- What is new: The research introduces an innovative method of synthesising magnesium and calcium battery materials — previously achievable only at very high temperatures and pressures — at ambient pressure and significantly lower temperatures.
- Why this is important: The development of magnesium and calcium batteries is hindered by the scarcity of viable electrode and electrolyte materials.
- What the research proposes: Utilizing solid-state metathetical reactions with alkaline-earth halides/nitrates and chalcogen- and pnictogen-based honeycomb layered oxides to create advanced battery materials at lower temperatures and ambient pressure.
- Results: Successful synthesis of $\rm Mg_3TeO_6$ polymorphs, ilmenite-type $\rm CaMg_2TeO_6$, and double perovskite $\rm Ca_2MgTeO_6$, demonstrating significant bulk ionic conductivity at room temperature, and extending the method’s applicability to create various advanced materials like bismuthates, antimonates, and phosphates.
