Self-Standing Hybrid Film of SnO₂ Nanotubes and MXene as A High-Performance Anode Material for Thin Film Lithium-Ion Batteries

A self-standing hybrid film was fabricated, which consists of SnO₂ nanotubes sandwiched by MXene nanosheets through alternate vacuum filtration. As an anode for lithium ion batteries (LIBs), the self-standing hybrid film delivers a reversible capacity of 663 mAh g⁻¹ after 100 cycles at 100mAg⁻¹ and exhibits excellent rate capability with a reversible capacity of 327mAhg⁻¹ at 5Ag⁻¹. The superior cycle stability and rate performance are achieved through the synergetic effect between SnO₂ nanotubes and MXene nanosheets, which provides a reference for the development of flexible batteries.
