摘要: The lengthened ion pathway in restacked 2D materials greatly limits the electrochemical performance of practically dense film electrodes (mass loading> 10 mg cm− 2). Typical strategies such as the insertion of nanomaterials and 3D‐structure design is expected to reduce the volumetric capacitance of Ti3C2Tx electrodes, diminishing the dominating advantage of Ti3C2Tx over other electrode materials. Here, a novel, facile, and controllable H2SO4 oxidation method is developed for alleviating the restacking issue of Ti3C2Tx film …
