Synthesis Of Titanium Compounds And Their Electrochemical Properties

Titanium compounds have attracted general attention for their applications in the fields of energy storage,electrocatalysis and photoelectric conversion due to their unique physical and chemical properties.They have been considered as the most promising candidates for the present anode materials of li-ion batteries?LIBs?because of their low cost,environment-benignity,high specific capacity,excellent conductivity and stable structure.In this work,TiN0.30 and TiN nanomaterials were synthesized by high temperature solid-state method.The discharge capacity of TiN0.30 and TiN are 136.8 and 140.5 mAh·g-1 at current density of 100 mA·g-1.The TiN0.30 nanomaterial was synthesized by nitriding method.The discharge capacity of TiN0.30 is 209.9 mAh·g-1 at current density of 100 mA·g-1,TiO nanoparticles which are obtained via solvothermal method show excellent cycling performance and discharge capacity of 382 mAh·g-1 after 800 cycles at current density of 50 mA·g-1,TiN/TiO₂ composites with 25% TiN own the best electrochemical performance and discharge capacity of 560.3 mAh·g-1 after 150 cycles,TiO₂/TiN nanofibers with reversible specific capacity of 366.9 mAh·g-1 after 100 cycles at current density of 100 mA·g-1.The structure,morphology and chemical elements of the synthesized samples were characterized and tested by XRD,SEM,EDS.The electrochemical properties of the synthesized samples were tested by means of battery test system and electrochemical workstation.
