This product, the NASICON Solid Electrolyte Sheet (Na₃Zr₂Si₂PO₁₂), is developed for solid-state battery research, particularly in the development of all-solid-state sodium-ion batteries. As an oxide-type solid electrolyte with the NASICON structure, it offers inherent chemical stability and moderate ionic conductivity suitable for laboratory-scale electrochemical testing. The sheet is available in a standard size of 16 mm diameter and 1 mm thickness, making it convenient for coin-cell assembly and impedance spectroscopy measurements. Produced by Canrd under the model MA-EN-SS-0005, this electrolyte material supports investigations into interface engineering, ion transport mechanisms, and the integration of solid electrolytes with electrode materials. Its crystalline NASICON phase enables consistent performance in solid-state device prototypes, serving as a reliable platform for evaluating next-generation battery chemistries.
