In article number 2100216, to solve the restacking problem of Ti3C2Tx MXene sheets, Haitao Huang and co-workers, develop a simple method using an ester reaction between ethanol and phosphoric acid to uniformly expand the interlayer space of the flexible Ti3C2Tx MXene film at the molecular scale to achieve enhanced ionic diffusion and high volumetric energy storage for supercapacitor applications.
