Flexible Free-Standing MoO₃/Ti₃C₂T _z MXene Composite Films with High Gravimetric and Volumetric Capacities.

ABSTRACT: Enhancing both the energy storage and power capabilities of electrochemical capacitors remains a challenge. Herein, Ti₃C₂T _z MXene is mixed with MoO₃ nanobelts in various mass ratios and the mixture is used to vacuum filter binder free, open, flexible, and free-standing films. The conductive Ti₃C₂T _z flakes bridge the nanobelts, facilitating electron transfer; the randomly oriented, and interconnected, MoO₃ nanobelts, in turn, prevent the restacking of the Ti₃C₂T _z nanosheets. Benefitting from these advantages, a MoO₃/Ti₃C₂T _z film with a 8:2 mass ratio exhibits high gravimetric/volumetric capacities
