Abstract

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.

基于含钛高炉渣的高稳定性二氧化钛/碳纳米管负极材料的构建

钛渣是炼铁过程中产生的重要矿渣资源，含有钛、钒、铝等贵重金属。钛渣的高效回收和高价值利用是该领域亟待解决的问题。本研究提出了一种以高钛渣为原料制备掺微量Fe和V的b-TiO2的创新方法。理论计算表明，Fe和V的掺杂提高了材料的导电性。利用十六烷基三甲基溴化铵（CTAB）的分散作用和碳纳米管（CNT）作为“骨架”的支撑作用，获得了具有高电化学性能的三维网状复合负极材料bc-TiO2/CNT。表现出优异的倍率性能，在2C条件下循环500次后容量保持率为76.07%。本研究对探索利用冶金工业渣资源作为储能材料具有重要意义。
