A Novel Strategy of In Situ Trimerization of Cyano Groups Between the Ti₃C₂T_x (MXene) Interlayers for High-Energy and High-Power Sodium-Ion Capacitors.

ABSTRACT: 2D MXenes are attractive for energy storage applications because of their high electronic conductivity. However, it is still highly challenging for improving the sluggish sodium (Na)-ion transport kinetics within the MXenes interlayers. Herein, a novel nitrogen-doped Ti₃C₂T_x MXene was synthesized by introducing the in situ polymeric sodium dicyanamide (Na-dca) to tune the complex terminations and then utilized as intercalation-type pseudocapacitive anode of Na-ion capacitors (NICs). The Na-dca can intercalate into the interlayers of Ti₃C₂T_x nanosheets and simultaneously form sodium tricyanomelaminate (Na₃TCM) by the catalyst-free trimerization. The as-prepared Ti₃C₂T_x/Na₃
