摘要
Abstract
To address the issues of poor hydrophilicity,insufficient active sites,and low electrochemical activity of graphite felt elec-trodes,this study develops a novel SrCo0.33Ni0.33Mn0.34O3 perovskite-type catalyst for vanadium redox reactions by optimizing the A-site element in the perovskite structure,substituting Sr2+for the conventional La3+.A perovskite/carbon felt composite electrode is subsequently fabricated.Electrochemical test results show that the vanadium redox flow battery(VRFB)assembled with the SrCo0.33Ni0.33Mn0.34O3 perovskite/carbon felt composite electrode achieves an energy efficiency of 82.5%at a current density of 150 mA/cm2.Moreover,even when the current density is increased to300 mA/cm2,the energy efficiency remains at66.4%,which is114.1%of that of LaCo0.33Ni0.33Mn0.34O3.In addition,after 300 charge-discharge cycles,the assembled single cell retains 95.9%of its initial energy efficiency,demonstrating excellent cycling stability.关键词
