title: Glycol Derived Carbon- TiO2as Low Cost and High Performance Anode Material for Sodium-Ion Batteries.
abstract: Carbon coated TiO2(TiO2@C) is fabricated by a convenient and green one-pot solvothermal method, in which ethylene glycol serve as both the reaction medium and carbon source without the addition of any other carbon additives. During the solvothermal process, ethylene glycol polymerize and coordinate with Ti4+to form the polymeric ligand precursor, then the polymer brushes carbonize and convert to homogeneous carbon layer firmly anchored on the TiO2nanoparticles (~1 nm thickness). The polymerization and carbonization process of the ethylene glycol is confirmed by FT-IR, Raman, TG and TEM characterizations. Benefiting from the well-dispersed nanoparticles and uniform carbon coating, the as-prepared TiO2@C demonstrate a high reversible capacity of 317 mAh g-1(94.6% of theoretical value), remarkable rate capability of 125 mAh g-1at 3.2 A g-1and superior cycling stability over 500 cycles, possibly being one of the highest capacities reported for TiO2.
