Abstract

Prelithiated, electrospun α-Fe₂O₃ nanofibers display an exceptional cycleability when it is paired with commercial LiMn₂O₄ cathode in full-cell assembly. The performance of such α-Fe₂O₃ nanofibers is mainly due to the presence of unique morphology with porous structure, appropriate mass balance, and working potential. Also, synthesis technique cannot be ruled out for the performance.
