## Description

- description: Multiwalled carbon nanotubes (MWCNTs) have shown effectiveness in improving
    MXenes’ accessibility for energy-related applications. However, the ability of
    individually-dispersed MWCNTs to control the structure of MXene-based macrostructures
    is unclear. Here, the correlation among composition, surface nano- and microstructure,
    MXenes’ stacking order, structural swelling, and Li-ion transport mechanisms and
    properties in individually-dispersed MWCNT-Ti3C2 films is investigated. The compact
    surface microstructure of MXene film, characterized by prominent wrinkles, is
    dramatically changed as MWCNTs occupy MXene/MXene edge interfaces. The 2D stacking
    order is preserved up to 30 wt% MWCNTs despite a significant swelling of ~400%.
    Such alignment is completely disrupted at 40 wt%, and a more pronounced surface
    opening and internal expansion of ~770% are realized. Both 30 wt% and 40 wt% membranes
    show stable cycling performance under a significantly higher current density due
    to faster transport channels. Notably, for the 3D membrane,　over-potential during
    repeated Li deposition/dissolution reactions is further reduced by ~50%. Ion-transport
    mechanisms in the absence and presence of MWCNTs are discussed. Furthermore, ultralight
    yet continuous hybrid films comprising up to ~0.027 mg/cm2 Ti3C2 can be prepared
    using aqueous colloidal dispersions and vacuum filtration for specific applications.
    The potential application of such ultralight membranes as interlayers for Li-O2
    batteries is briefly examined.
