氢气还原制备一氧化钒试验研究
Experimental study of vanadium monoxide synthesis via hydrogen reduction
摘要
Abstract
Vanadium monoxide(VO),recognized as a potential anode material for high-energy and high-power lithium-ion batteries(LIBs),is limited in its application as an electrode material due to its low purity,high cost and complex process in existing synthesis process.The authors propose a novel hydro-gen reduction process for VO synthesis using V2O3 as the raw material and H2 as the reducing agent.The key parameters such as reduction temperature,reaction duration,and others were systematically in-vestigated.The preparation of VO is achieved through the V-H-O multiphase reaction,and the resulting VO powder particles have relatively smooth surfaces,presenting an approximating spherical or ellips-oidal shape.The XRD diffraction pattern closely matches with the reference diffraction pattern,with ac-curate peak positions,sharp profiles,and narrow full widths at half maximum,indicating excellent crys-tallinity.By optimizing parameters,the optimal reduction conditions were determined.When the reduc-tion temperature is 1 500℃,the reaction time is 5.5 h,hydrogen flow rate is 0.264 cm/s,the vanadium content is about 78.27％,which is consistent with VO0.80-VO1.20.关键词
