MXenes are a class of two-dimensional (2D) transition-metal carbides and nitrides that are currently at the forefront of 2D materials research. In this study, we demonstrate the use of metallically conductive free-standing films of 2D titanium carbide (MXene) as current-collecting layers (conductivity of ∼8000 S/cm, sheet resistance of 0.5 ω/sq) for battery electrode materials. Multilayer Ti 3 C 2 T x (T x : surface functional groups -O, -OH, and -F) is used as an anode material and LiFePO 4 as a cathode material on 5 μm MXene films. Our results show that the capacities and rate performances of electrode materials using Ti 3 C 2 T x MXene current collectors match those of conventional Cu and Al current collectors, but at significantly reduced device weight and thickness. This study opens new avenues for developing MXene-based current collectors for improving volumetric and gravimetric performances of energy-storage devices.
