ability. In this work, FeFe(CN)6 (FeHCF) is synthesized as a cathode material for aqueous NH4+ batteries and Fe2(SO4)3 is utilized as a kind of functional additive in the electrolyte based on the “common ion effect” to enhance its electrochemical performance. The results indicate that the initial capacity of FeHCF is about 80 mA h g−1 with a coulombic efficiency of 97.8%. The retention rate can attain 96
为了满足不断增长的电网储能需求,
水性NH 4 +电池由于其对环境的重要性,丰富的资源和快速的扩散能力,作为一种有前途的替代品正受到越来越多的关注。在这项工作中,合成了FeFe(CN)6(FeHCF)作为用于NH 4 +
水性电池的正极材料,并且基于“共离子效应” ,Fe 2(SO 4)3被用作电解质中的一种功能添加剂。以增强其电
化学性能。结果表明,FeHCF的初始容量约为80 mA hg -1库仑效率为97.8%。在近1000个周期内保留率可达到96.3%。进行了多变量分析方法以表征NH 4 +
水溶液中FeHCF的机理。从实际的角度来看,FeHCF具有出色的循环稳定性和倍率性能,使其在电网中的应用变得可行。
