$ TiS_{2} $ As Negative Electrode Material for Sodium-Ion Electric Energy Storage Devices

Abstract Titanium disulfide ($ TiS_{2} $) was synthesized by a simple solid phase method. The physical properties of $ TiS_{2} $ were investigated using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and energy dispersive X-ray spectroscopy (EDX). Scanning and transmission electron microscopy (SEM and TEM) were used to study the structural and morphological characteristics. The synthesized $ TiS_{2} $ was applied as negative electrode material for $ TiS_{2} $/graphite electric storage devices with organic electrolytes based on $ Na^{+} $-ions. The electrochemical methods were used to characterize the charge storage mechanism of $ TiS_{2} $. The $ TiS_{2} $/graphite electric energy storage device possessed a working voltage of 3.5 V. The fabricated device showed relatively high performance rate and excellent cycle stability in electrochemical tests..
