Electrochemical performance of TiO2–C nanocomposite as an anode material for lithium-ion battery

Abstract

The Titanium dioxide–Carbon (TiO2–C) nanocomposite (NC) was fabricated by a hydrothermal method. The present work is to introduce the carbon material in Li-ion batteries for optimizing it to better electrical performance and to enhance its property. Lithium-ion battery is prepared by using titanium tetrachloride and commercial filter paper as the carbon source. The battery performance is highly influenced by the weight ratio of TiO2–C in the sample. For this work, a new method is adapted to tune the weight percentage of TiO2 and carbon in the composite while elevating calcination temperatures. Optimized battery performance of TiO2 nanocomposite was analyzed by 150 cycles at various calcination temperatures viz., 400 °C, 450 °C, and 500 °C, the charge capacities have existed at 301 mAh g−1, 352 mAh g−1, and 402 mAh g−1 at a current density of 100 mA g−1. The first discharge capacity was achieved for three prepared samples (400 °C, 450 °C, and 500 °C) to be 1068 mAh g−1, 1271 mAh g−1, and 1467 mAh g−1 at a current density of 100 mA g−1. The prepared electrode shows high charge and discharge capacity during long cycling.
