Sulfur-Doped TiO2 Anchored on a Large-Area Carbon Sheet as a High-Performance Anode for Sodium-Ion Battery
Source abstract
Abstract
Well-tailored sulfur-doped anatase titanium dioxide nanoparticles anchored on a large-area carbon sheet are designed, where the in situ sulfur-doped titanium dioxide directly comes from titanium oxysulfate and the large-area carbon sheet is derived from glucose. When applied as an anode material for sodium-ion batteries, it exhibits an excellent electrochemical performance including a high capacity [256.4 mA h g–1 at 2 C (1 C = 335 mA h g–1) after 500 cycles] and a remarkable rate of cycling stability (100.5 mA h g–1 at 30 C after 500 cycles). These outstanding sodium storage behaviors are ascribed to the nanosized particles (about 8–12 nm), good electronic conductivity promoted by the incorporation of carbon sheet and sulfur, as well as the unique chemical bond based on the electrostatic interaction.
