Two-dimensional (2D) carbide Ti 3 C 2 was synthesized by exfoliating Ti 3 AlC 2 in HF solution and used for supercapacitive performance investigation in 3 M KOH electrolyte. The specific surface area (SSA) of as-synthesized Ti 3 C 2 was 22.35 m 2 /g. Ti 3 C 2 -based supercapacitor electrodes exhibited good energy storage ability and had a volumetric capacitance 119.8 F/cm 3 at the current density of 2.5 A/g. Moreover, the addition of carbon black into Ti 3 C 2 powders greatly improved the performance of Ti 3 C 2 -based capacitors because carbon black restrained the preferred orientation of 2D Ti 3 C 2 , providing fast ion transport channels, and in turn, decreasing electrical resistance from 16.7 Ω to 3.5 Ω.

“…41 A more perfect straight line (a bigger straight-line slope rising from low frequency) for NiMoO 4 /PPy than for PPy and NiMoO 4 proves that the capacitive properties for the composite have been enhanced. 42,43 On the contrary, NiMoO 4 /PPy exhibits smallest R ct apart from the small R s , indicative of the best electrical conductivity and electroactivity. Tightly coated PPy promotes both the electrical conductivity of each NiMoO 4 nanorod and the electrical contact of NiMoO 4 with Ni foam current collector, resulting in the upmost utilization of NiMoO 4 in the course of the electrochemical reactions.…”

Electrodes of rationally designed composite nanostructures can o®er many opportunities for the enhanced performance in electrochemical energy storage. This paper attempts to illustrate the design and production of NiMoO 4 /polypyrrole core-shell nanostructures on nickel foam to be used in supercapacitor via a facile hydrothermal and electrodeposition process. It has been veri¯ed that this novel nanoscale morphology has outstanding capacitive performances. While employed as electrodes in supercapacitors, the composite nanostructures showed remarkable electrochemical performances with a great areal capacitance (3.2 F/cm 2 at a current density of 5 mA/cm 2 ), and a signi¯cant cycle stability (80% capacitance retention after 1000 cycles). The above results reveal that the composite nanostructures may be a likely electrode material for high-performance electrochemical capacitors.
