| Abstract Scope |
Na Super Ionic Conductors (NASICONs) are polyanionic materials with a general formula NaxM2(AO4)3, where M represents a main group or transition metal and AO4 represents a polyanion. Due to their high ionic conductivity and superior chemical and electrochemical stability, NASICON materials are extensively studied as important solid-state electrolytes/cathodes for high-energy/power-density and safe batteries, and have other interesting membrane applications, such as desalination, gas sensing, and caustic recovery from nuclear waste. However, the Na-ion conductivity of most existing NASICON materials still needs to be further increased to improve their application performance. However, NASICON materials inherently have complex compositions, making it difficult to synthesize phase-pure NASICON materials and to manufacture them into fully densified membranes, especially mechanically robust thin films. Here, we report a solid-state reactive method to fabricate NASICON with a desired microstructure for high Na-ion conductivity. |
