以LiNO3为反应介质，通过低温熔盐法制备了纳米Ag2V4O11粉末。这些粉末已通过 X 射线衍射和透射电子显微镜进行了表征。粉末的放电特性已通过使用 CR2016 纽扣电池的恒电流放电测试进行了评估。在300℃下2h制成的粉末由尺寸约为40nm的近球形颗粒组成。放电测试表明，低温熔盐法制备的粉末表现出较高的放电容量。
Nanosized Ag2V4O11 powders have been prepared via the low-temperature molten salt method using LiNO3 as a reaction medium. The powders have been characterized by x-ray diffraction and transmission electron microscopy. The discharge properties of the powders have been assessed by the galvanostatic discharge test using CR2016 coin cells. The powder made at 300 degrees C for 2 h is composed of nearly spherical particles about 40 nm in size. The discharge test shows that the powders prepared by the low-temperature molten salt method exhibit high discharge capacities.
