An electrolyte was prepared using ammonium metavanadate (AMV) to apply in the all-vanadium redox flow battery (VRFB). The component and composition of the prepared electrolyte by AMV were analyzed by X-ray diffraction (XRD) and inductively coupled plasma (ICP). It was confirmed from the analysis results that the component was almost the same as that of vanadyl sulfate and the composition was almost the same as that of prepared by 2.1 mol of the vanadyl sulfate dissolved in 3 M H2SO4. The cell performance of VRFB using the prepared electrolyte by AMV was measured at current density of 60 mA cm−2. The efficiency of VRFB using the prepared electrolyte by AMV was 97.66%, 86.31%, 84.30% for an average current efficiency, average voltage efficiency and average energy efficiency, respectively. It was expected that the prepared electrolyte by AMV was usable as the electrolyte of VRFB from the viewpoint of the cell performance.

偏钒酸铵电解液全钒液流电池的特性

使用偏钒酸铵 (AMV) 制备电解质,用于全钒氧化还原液流电池 (VRFB)。采用X射线衍射(XRD)和电感耦合等离子体(ICP)分析了AMV制备的电解液的成分和组成。由分析结果确认,其成分与硫酸氧钒几乎相同,组成与将2.1mol的硫酸氧钒溶解在3 MH 2 SO 4中的组成也几乎相同。在 60 mA cm -2的电流密度下测量使用 AMV 制备的电解质的 VRFB 的电池性能. 使用AMV制备的电解液的VRFB的平均电流效率、平均电压效率和平均能量效率分别为97.66%、86.31%、84.30%。从电池性能的角度来看,预计通过AMV制备的电解质可用作VRFB的电解质。
