Abstract: Freestanding and bendable film fabricated by 2D materials has demonstrated great potential as an electrode for energy storage devices, owing to their paramount flexibility, structural stability and high conductivity. Nevertheless, the unavoidable restacking of 2D material sheets substantially limits their electrochemical performance. Here, two dimensional-based film electrodes were fabricated through the different methods with mechanically shearing 2D Material sheets that are in liquid crystalline discotic lamellar phase assembly of liquid crystal, and intercalating 2D material interlayers with spacers/dopant methods. The introduced active materials provide abundant active sites to augment the electrode storage capacity. The enlarged interlayer spacing facilitates the transport of electrolyte ions. As a result, the optimized film electrodes exhibit a high specific capacitance, impressive rate capability and ultrastable cycling. Those works provide the effective routes for assembling 2D material sheets for high-performance energy storage devices.
