Electrochemical synthesis and research of nanotubes of titanium dioxide as an anode material for lithium-ion battery
Abstract
Electrochemical synthesis of TiO2-nanotube performed in electrolytes of different composition when applied to a cell potential of 60 V for 5 hours. Titania nanotube obtained were examined by scanning electron microscopy (SEM). Electrochemical characteristics of nanotubes determined by chronopotentiometry and voltammetry methods in a three-electrode cell with a platinum counter electrode and Li/Li+ reference electrode in an electrolyte of 1M LiClO4 in propylene carbonate (PC). On the polarization curves of these materials have been several waves of lithium intercalation in the potential range from 2.0 V to 0 V, indicating that the stepwise mechanism of the process of lithium intercalation. Also in the anode area is allocated a distinct peak deintercalation of lithium ranging from 2.0V to 3.0V. Enough good repeatability of cycles shows a good reversibility of the process and the stability of the material during cycling. It has been found that the best electrochemical characteristics have material synthesized in the electrolyte №2 an electrochemical method and has capacity 78.6%.References
