Abstract
Supermolecular complexation with cyclodextrins by non-covalent host-guest interaction is used for various applications. In this work, we fabricated the freestanding and flexible core-shell MnO/carbon nanofiber (CNF) composite thin films by host-guest interaction and high-voltage electrospining technique. The as-prepared composite thin film with dual carbon layer nanofibers showed smaller MnO particle size, lower electron-transfer resistance, and faster lithium ion migration, which were attributed to intermolecular non-covalent assembling behavior among polyacrylonitrile (PAN), β-cyclodextrin (β-CD) and Mn ion. As expected, the composite film as anode in Li-ion battery showed impressive performance: a high reversible capacity (∼1025 mAh g−1 at ∼0.1 A g−1), excellent rate capability (∼376 mAh g−1 at ∼5 A g−1), and superior cyclability (∼844 mAh g−1 at the current density of ∼1 A g−1 after 800 cycles). Such outstanding electrochemical performance endows the MCNFs composites with great potential as anode material for LIBs.
