Study of Counter Electrodes as an Effective Controlling Factor of Crystal Orientation of TiO2 Nanoarrays Used as the Anode in Lithium-Ion Batteries

Abstract

In this paper, we report the synthesis of titanium dioxide nanoarrays (TNAs) by an anodizing process using different counter electrodes including Pt, Ni, Ti, Cu, Al, and graphite. The synthesized TNAs are studied as anode material for lithium ion batteries. Crystallographic structure and surface morphology of the TNAs are studied using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The electrochemical tests of the TNAs-Li half-cells are carried out using cyclic voltammetry (CV), charge/discharge analysis, and electrochemical impedance spectroscopy (EIS). These results show the TNAs morphologies and crystallography strongly depend on the type of counter electrode. The synthesis of TNAs using Pt and Al as a counter electrode leads to the highest and lowest crystal growth in the preferred 001 direction, respectively, in comparison with other counter electrodes. The anodized TNAs using Pt counter electrode illustrate an acceptable cycleability and rateability up to 100 cycles.
