ABSTRACT
Given these advantages of widely designable structures and environmentally friendly characteristics, organic electrode materials (OEMs) are considered to be promising electrode materials for alkaline metal-ion batteries. However, their large-scale application is hampered by insufficient specific capacity and rate performance. Here, Fe2+ is coupled to the anhydride molecule NTCDA to form a novel K-storage anode Fe-NTCDA. In this way, the working potential of Fe-NTCDA anode is reduced, which makes it more suitable to be used as an anode material. Meanwhile, the electrochemical performance is significantly improved due to the increase in K-storage sites. Moreover, electrolytes regulation is implemented to optimize the K-storage behavior, resulting into a high specific capacity of 167â
mAh/g after 100 cycles at 50â
mA/g and 114â
mAh/g even at 500â
mA/g in the 3â
M KFSI/DME electrolytes.
