The feasibility of developing a rechargeable iron ion battery is demonstrated for the first time. A rechargeable iron ion battery using mild steel as the anode and vanadium pentoxide as the cathode is demonstrated to deliver a specific capacity of 207 mA h g-1 at 30 mA g-1. Using ex situ characterisation techniques, reversible intercalation of iron ions into a host structure is confirmed.
首次证明了开发可充电铁离子电池的可行性。一种以低碳钢为阳极、五氧化二钒为阴极的可充电铁离子电池,在30 mA g-1的电流密度下,比容量达到207 mA h g-1。通过非原位表征技术,证实了铁离子可在主体结构中可逆嵌入。
