摘要

Titanium slag is a highly important slag resource generated during the iron smelting process, containing valuable metals such as titanium, vanadium, and aluminum. The efficient recovery and high value utilization of titanium slag is an urgent problem to be solved in this field. This study proposes an innovative method to prepare b-TiO2 doped with trace amounts of Fe and V using high-titanium slag as the raw material. Theoretical calculations show that the doping of Fe and V enhances the conductivity of the material. By utilizing the dispersing effect of cetyltrimethylammonium bromide (CTAB) and the supporting effect of carbon nanotubes (CNT) as a "skeleton," a three-dimensional network composite negative electrode material, bc-TiO2/CNT, with a high electrochemical performance is obtained. It exhibits excellent rate performance, with a capacity retention rate of 76.07% after 500 cycles at 2C. This study is of great significance for exploring the use of metallurgical industry slag resources as energy storage materials.
