Abstract:
Since the last decades, Lithium-ion batteries, the most common type of secondary rechargeable batteries, have gained wide attention in electrical energy storage and almost in all portable electronic devices. The demand for lithium-ion batteries as a major power source is rapidly increasing. However, their high price discourages the large-scale energy storage. Therefore, in order to use abundant source of sodium based compound, researchers are focusing on Na+ based rechargeable batteries. In the present study, glass samples have been synthesized with composition xNa2S + (100-x) P2S5 at different x. These glass samples have been further heat treated above their crystallization temperatures under Argon atmosphere to get glass-ceramics. These glass/glass-ceramic samples have been characterized by various techniques XRD, DTA/TG, FT-IR, Dilatometer, Raman spectroscopy and Impedance spectroscopy. The XRD patterns of all samples showed a broad halo indicating its amorphous nature. The synthesized glasses show different glass transitions and crystallization temperatures at different compositions. Synthesized glasses show that x = 45 and x = 55 mol % Na2S have minor structural changes as compared to other samples. At room temperature, synthesized glasses show a conductivity in the range of (10-8-10-5)S/cm-1, which is comparable to that of Li ion based solid electrolyte. Present glass/glass-ceramic samples might be used as an electrolyte in Na-ion batteries and can substitute lithium-ion batteries at room temperature.
