TiS2 as negative electrode material for sodium-ion supercapattery
Titanium disulfide (TiS 2 ) was adopted as a negative electrode material for the asymmetric sodium-ion supercapattery of TiS 2 /activated carbon using Na + -based organic electrolytes. This type of supercapattery possesses a working voltage as high as 3 V. The physical properties of the negative ele...

-based organic electrolytes. This type of supercapattery possesses a working voltage as high as 3 V. The physical properties of the negative electrode were characterized by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. The electrochemical performance tests revealed that the supercapattery had a relatively high rate performance and good cycle stability, displaying 77% capacity retention after 1000 cycles at a current density of 0.2 A g
