Hybrid-ion strategy enables ultra-long life aqueous iron-organic batteries

Rechargeable iron-ion (Fe-ion) batteries: recent progress, challenges, and perspectives

“…The reversible electroplating and stripping processes are higher for three molar Fe(OTF) 2 than for the other electrolytes. 99 A comparison between FeSO 4 and Fe(OTF) 2 was also performed based on the VOPO 4 -based cathode, where the Fe(OTF) 2 electrolyte showed high cyclic performance along with high cycling stability, as shown in Fig. 3(g).…”

“…A detailed computational study also showed the interaction between the PANI and CF 3 SO 3 − ions, substantiating the experimental findings. 99…”

“…103–105 High-purity iron foil, iron plates, Fe foam, or iron sheets are widely used as anode materials in various aqueous Fe-ion batteries. 96,98–100,108,111,113,114,127 Iron nanoparticle powder was also used as the anode material after mixing with a binder and carbon-based conducting agent, as reported in various findings for aqueous Fe-ion batteries. 92–94 All the anode materials used in Fe-ion batteries for the non-aqueous and aqueous electrolytes are also summarized in Tables 1 and 2, respectively.…”
