Developing an advanced transparent conductive electrode (TCE) as a substitute for the fragile and high-cost indium tin oxide (ITO) is top priority in coming smart electronics era. Although two-dimensional transition metal carbides nitrides (MXenes) have revealed great potential competition, figure of merits (FoMe, defined ratio direct current conductivity to optical conductivity) reported MXenes TCEs are far below minimum industrial requirement. Herein, we report on breaking FoMe limitation by hybrid nanoimprint-blading technique construct embedded MXene grids, where fine slot channels filled with flakes space beyond left empty, allowing more visible light pass through, thus substantially improving transmittance. Such strategy decouples correlation between transmittance sheet resistance achieves their individual regulation. As result, obtain ultrahigh (∼84) surpassing most other nonmetal even being competitive ITO. We demonstrate application grid TCE electrochromic device, showing satisfactory switching time excellent stability (>38,000 cycles). This work opens vast opportunities flexible applications.
