| 摘 要： | 针对氢气焙烧还原偏钒酸铵（AMV）制备全钒液流电池V2O3的试验条件、晶相和微观结构的影响展开研究。结果表明，优选试验条件为：氢气还原温度575 ℃、氢气还原时间1 h、氢气气流速率100 mL/min、还原后随炉冷却。通过上述试验方案获得的样品基本全部为V2O3，主晶相为V2O3，微观结构上晶粒饱满且以片状物或块状物的形式紧密堆积在一起。最终可生产电池级V2O3，并制备出合格的全钒液流电池电解液。

| Abstract: | The effects experimental conditions, crystal phase and microstructure of V2O3 for vanadium redox battery prepared by hydrogen roasting and reduction of ammonium metavanadate (AMV) were studied. The results show the optimal test conditions include hydrogen reduction temperature of 575 ℃, hydrogen reduction time of one hour and hydrogen gas flow rate of 100 mL/min, and cooling with furnace after reduction. The samples obtained by the above test scheme are basically all V2O3, the main crystal phase is V2O3, and the grains are full in microstructure and tightly packed together in the form of flake or block. Finally, the battery grade V2O3 can be produced, and qualified vanadium redox battery electrolyte can be prepared. |
