Summary: Two-dimensional MXenes are efficient electrochemical capacitors with high energy and power densities. V2CTx MXene, as one of the lightest members, is limited in its effective use due to restacking. A composite of ZrO2-MXene was reported, where ZrO2 nanparticles were grown on V2CTx MXene sheets. The interconnected structure boosted conductivity and suppressed restacking. This composite showed outstanding capacitance and cyclic stability.
