Effect of annealing on electrochemical performance of anodized Tio2 nanotubes for lithium ion batteries

Journal Article


Abstract


  • The effect of annealing on TiO2 nanotube arrays as anode for lithium ion batteries by X-ray diffraction, field

    emission scanning electron microscopy, cyclic voltammetry, galvanostatic charge-discharge testing, and electrochemical

    impedance spectroscopy was investigated. The crystalline structure of TiO2 nanotube can be changed

    by controlling the annealing temperature and the crystallization also has considerable effect on electrochemical

    performance. Amorphous TiO2 annealed at 250 C shows the highest discharge capacity in coin cell tests with

    a discharge capacity of about 67 Ah cm−2 and good cycling stability during 50 charge-discharge cycles. The

    electrochemical impedance spectroscopy results show the smallest resistance compared to the other samples.
