Sodium-doped electrolyte for advanced energy storage devices

Abstract

A sodium oxide-doped oxynitride glass-ceramic electrolyte includes Na3.6K1.4Ca5.7Mg3.6Al12.6Si16.5O50N6.8 and Na2O, where the sodium oxide-doped oxynitride glass-ceramic is formed by spark plasma sintering a mixture including the Na3.6K1.4Ca5.7Mg3.6Al12.6Si16.5O50N6.8 and the Na2O. The amount of Na2O present in the mixture is in a range from 3 wt. % to 12 wt. % of the total weight of the mixture. The sodium oxide-doped oxynitride glass-ceramic has an alternating current (AC) conductivity greater than or equal to 5×10−11 siemens per centimeter (S·cm−1) measured at 295-degree kelvin (K) and a frequency of 100 Hertz (Hz).
