| Abstract Scope |
The development of solid-state batteries has garnered attention as a feasible energy storage solution for the next generation of energy devices due to their high energy density, safety, and improved longevity. Among all solid electrolytes, NASICON (Sodium Ion Super Conductors) offers good thermal and electrochemical stability, and high ionic conductivity. However, it remains challenging to manufacture doped-NaSICON solid electrolytes with high ionic conductivity at room temperature while remaining low electronic conductivity. This study investigated yttrium dopant and its doping strategy to enhance the ionic conductivity. Y-doped NaSICON were synthesized using mechanical activation with one high temperature reaction. The resulting Y-doped NaSICON exhibited a total ionic conductivity of 8.03x10-4 S/cm, which is nearly 2.5 times higher than the very best ionic conductivities synthesized via solid-state reaction and sol-gel method. This study provides an alternate solution for synthesizing high ionic conductive NaSICON at low cost for many energy storage systems. |
